The cost of 18 slices of pizza is $18.
The monthly cost for x slices of pizza is $25 + x
What is the monthly cost?The equation that represents the amount of money that Ava would have to pay when she buys 18 slices of pizza is a linear equation. A linear equation is an equation that has one variable raised to the power of one. The linear equation increases by a fixed amount. When drawn on a coordinate plane, a linear equation is a straight line.
The total monthly cost is a function of the membership fee, the cost per pizza and the number of pizzas bought.
The form of the linear equation is :
fx = mx + b
b = slope m = interceptTotal amount paid = membership fee + total cost of pizzas
Total amount paid for 18 pizzas = cost per pizza x number of pizzas bought
$18 x 1 = $18
Total monthly cost for x pizzas = membership fee + (discounted price x number of pizzas bought)
$25 + ($1 x x)
$25 + $1x = $25 + $1x

The following figure is made of a square and a rectangle.
What is the perimeter of the figure?
Consequently, the combined perimeter of the square and rectangle in the previous diagram is 36 cm.
What is the perimeter of the quadrilateral?We combine each side's value.
For instance, the typical solution is to multiply the length by two and the width by two, then add the results to determine the perimeter if the quadrilateral is a square, rectangle, parallelogram, or any other shape with two equal opposite sides and angles.
In the given diagram, we can infer that
the diagram is a combination of a square and a rectangle
so for the rectangle:
the perimeter is =2(l+b)
=2(8+5)
=26 cm
so for the square :
the perimeter is =2(side +side):
=2(5+5)
=20cm
to get the total perimeter ,we will add both the perimeters but subtract one side (5cm) because it is common in both the quadrilaterals twice:
so we get:
20+26-10=36cm
Therefore, the perimeter of the preceding diagram of a square and a rectangle combined is 36cm.

In the following exercise, two sides and an angle are given. First determine whether the information results in no triangle, one triangle, or two triangles. Solve the resulting triangle.
a=229,b=244, and A = 37.8°
By the Law of Sines,
[tex]\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \sin B=\frac{b \sin A}{a} \\ \\ =\frac{244\sin 37.8^{\circ}}{229} \\ \\ B \approx 37.42^{\circ}, 142.58^{\circ}[/tex]
Of these, only 37.42° is a possible value of B (sum of angles of a triangle is 180°).
So, we have that:
[tex] a=229, b=244, A=37.8^{\circ}, B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]
Angles of a triangle add to 180°, so:
[tex]C=180^{\circ}-A-B=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)
[/tex]
Using the Law of Sines again,
[tex]\frac{c}{\sin C}=\frac{a}{\sin A} \\ \\ c=\frac{a \sin C}{\sin A} \\ \\ =\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}}[/tex]
So, there is one possible triangle, where:
[tex]a=229 \\ \\ b=244 \\ \\ c=\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}} \\ \\ A=37.8^{\circ} \\ \\ B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right) \\ \\ C=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

Find the equation of the line.
a line that is perpendicular to the graph of y=-3x +2 and
contains the point (3,-3)
Answer: y = -3x + 6
Step-by-step explanation:
If it is perpendicular to the line -3x + 2, then it's slope should also be -3.
The standard form of a line is y = mx + b. As our slope is -3, we have that our line is y = -3x+b. Now, let's put the given point into the line. x = 3 and y = -3, so -3 = -3*3 + b. Hence, b = -3+9 = 6. The equation of the line is y = -3x + 6.

In two or more complete sentences, describe the transformation(s) that take place on the parent function f(x)=log(x) to achieve the graph of g(x)=log(-3x+9)+4.
The transformation that takes place on the parent function ( f (x) = log (x) ) to achieve the graph of g(x)=log(-3x+9)+4 can be described as a reflection across the y-axis. Then you horizontally shrink a factor of three; shift three units to the right, and shift four units upwards.
The explanation is as follows:Step 1: The parent graph is to be translated 3 units to the right side to achieve: y = log (x-3)
2. Shrink the graph by a factor of three by multiplying x by three:
⇒ y = log 3(x-3)
3. Reflect the function y = log 3(x-3) across line -3 = x to achieve:
y = -3(x-3)
4. Translate the function y = log 1-3(x-3) four units upwards to achieve
y = log (-3 + 9) +4

Write the vertex form of the following function. (fill in each blank with the correct numerical
value: include the sign where needed)
An absolute value function with a vertex of (-12,10) and passes through the points (4, 6) and
(-8, 9).
Answer:
-1/4 Abs(x+12) + 10
Step-by-step explanation:
The vertex form of an absolute function is of the form
y = a|x -h| + k here |x-h| is the absolute value
where (h, k) are the coordinates (x, y) of the vertex
The vertex is given as (-12, 10)
So h = -12, k = 10
Plugging these in we get the vertex form as
y = a|x - (-12)| + 10
y = a|x + 12| + 10
All it remains is to find a
Given point (4, 6) as a point on the graph, plug these values
y = 6 = a|4 + 12| + 10
6 = a|16| + 10
6 = 16a + 10 since absolute value of a positive number is the number
Switch sides
16a + 10 = 6
Subtract 10 from both sides:
16a + 10 - 10 = 6 - 10
16a = -4
a = -1/4
So the equation of the function is
y = -1/4|x + 12| + 10
The second point is not needed to derive the function equation but let's use it to verify our calculated equation
Point (-8, 9)
Plug x = -8, into y = -1/4|x + 12| + 10
=> y = -1/4|-8+12| + 10
=> y = -(1/4)·4 + 10
=> y = -1 + 10
= y = 9 which matches with the y -coordinate of the second point
So everything looks cool
Final Solution
-1/4 Abs(x+12) + 10
For - 1/4 if it does not accept fractions, enter -0.25

Nara wants to determine how much ice it will take to fill her cooler . If the cooler has a length of 22 inches, a width of 12 inches, and a height of 1012 inches, how much ice will her cooler hold?
Answer:
267,168 inches
Step-by-step explanation:
If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.
Volume = L × W × H
Where,
L means lengthW means widthH means heightVolume = 22 inches × 12 inches × 1012 inches
Volume = 267,168 inches
So, her cooler can hold 267,168 inches of ice

The greatest possible integer value for the mean is calculated as 59.
What is defined as the consistent solution?A system is said to be consistent if it has at least one solution. A consistent system is independent if it has exactly one solution. It is dependent if a consistent system has had an infinite number of solutions.Assume that the three piles contain A,B,C rocks, that mean of pile C is x, and the mean of a combination of B and C is y. We will maximize y if the following conditions are met:
40A + 50B = 43(A+B)
40A + xC = 44(A+C)
50B + xC = y(B+C)
that can be reorganized as follows:
7B = 3A
(x - 44)C = 4A
(x - y)C = (y - 50)B
Let's see if y=59 is possible. If so, it's already the solution. Otherwise, there will be an inconsistency. As a result, the third equation is as follows:
(x - 59)C = 9B.
So, 15C = (x-44)C - (x-59)C = 4A - 9B
45C = 4(3A) - 27B = 28B - 27B,
105C = 28A-9(7B) = A
Thus,
A = 105C, B = 45C, Put the values
x = 4(105) + 44 = 464, That gives consistent solution.
Therefore, the value of y is found to be 59, the greatest possible integer value for the mean.

In late 1897, Amos Dolbear published an article called “The Cricket as a Thermometer." He had determined that the outside temperature (in Fahrenheit) shared a linear relationship with the number of times the snowy tree cricket would chirp per . If you count the number of cricket chirps per (while sitting inside your warm house), then you can find the temperature outside. In his research, Dolbear concluded that for every extra cricket chirp per second, the temperature was 1/4*F higher. Furthermore, he found that when the number of cricket chirps per minute was 120, the temperature outside was 70*F.
What are the quantities in this scenario?

Please mark as brainliest
Step-by-step explanation:
the area of a rectangle is
length × width = 300 ft²
length = width + 5
(width + 5) × width = 300
width² + 5×width = 300
width² + 5×width - 300 = 0
the general solution to such a quadratic equation is
width = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 5
c = -300
width = (-5 ± sqrt(5² - 4×1×-300))/(2×1) =
= (-5 ± sqrt(25 + 1200))/2 =
= (-5 ± sqrt(1225))/2 = (-5 ± 35)/2
width1 = (-5 + 35)/2 = 30/2 = 15 ft
width2 = (-5 - 35)/2 = -40/2 = -20 ft
negative lengths for an actual object don't make sense, so width = 15 ft is our solution.
length = width + 5 = 15 + 5 = 20 ft

The unknow angles are as follows:
m∠1 = 108 degreesm∠2 = 72 degreesm∠5 = 108 degrees.m∠7 = 108 degreesm∠8 = 72 degreesHow to find angles in parallel lines?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
Therefore,
m∠4 = 72 degrees
Hence,
m∠1 + m∠4 = 180 (angle on a straight line)
m∠1 = 180 - 72
m∠1 = 108 degrees
m∠2 = m∠4 (vertically opposite angles)
Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.
Therefore,
m∠2 = 72 degrees
m∠5 = m∠1 (corresponding angles)
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.
m∠5 = 108 degrees.
m∠7 = m∠5(vertically opposite angles)
m∠7 = 108 degrees
m∠8 = m∠2 (alternate exterior angles)
Alternate exterior angles are congruent.
