2. What is the value of x when y = 17 for the quadratic function
f(x) = x² + 6x + 10?
A. -7 only
B. 1 only
C. 7 only D. -7 and 7
E. -7 and 1
Value of x when y = 17 for the quadratic function f(x) = x² + 6x + 10 is -7 and 1. That is option E.
Given, y=17 :
17 = x² + 6x + 10
Move 17 to RHS (right-hand side) :
0 = x² + 6x - 7
Using the Middle Splitting method:
0 = x² + (7x - 1x) - 7
0 = x(x + 7) - 1(x+7)
0 = (x - 1) (x + 7)
Now, equate both the equations (x-1) and (x+7) separately with 0.
The first value of x is
(x - 1) = 0
x = 1
The second value of x is
(x + 7) = 0
x = -7
∴ The values of x are -7 and 1. According to the question, that is option E.

what is the following solution to this absolute value equation?
6|-f + 3| + 7 >7
The solution of this absolute value equation is f<3
What is absolute value?Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.
On subtracting 7 from both sides
=6|-f + 3| + 7 - 7 > 7 - 7
=6|-f + 3| > 0
Now diving both sides by 6
|-f + 3| > 0
Now, this results in two condition

2.) -(-f+3)<0
So,

2 If x and y vary directly and y=32 when x=18, then which of the following equations correctly represents
the algebraic relationship between x and y?
(A)y=16/9x
(B)y=x+14
(C) x+y=50
(D)y=9/16x
The equation would be y = 16/9x which represents the algebraic relationship between x and y which is the correct answer would be an option (A).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that x and y vary directly and y = 32 when x = 18
Direct variation equation can be written as:
y = kx where "k" is a constant.
Substitute the values of y = 32 and x = 18 in the direct variation equation and solve for k:
⇒ 32 = k(18)
⇒ k = 32/18
⇒ k = 16/9
The direct variation equation :
⇒ y = 16/9x
Therefore, the equation would be y = 16/9x which represents the algebraic relationship between x and y.

If m = 8 and 3m + 72=4y – 56, then by the Substitution Property of Equality, 3(8) + 72 = 4y − ???
Answer:
56
Step-by-step explanation:
3m + 72 = 4y - 56
3(8) + 72 = 4y - 56
24 + 72 = 4y - 56
96 = 4y - 56
4y = 152
y = 38
3(8) + 72 = 4y - x
24 + 72 = 152 - x
96 = 152 - x
-56 = -x
x = 56
An artist has been commissioned to make a stained glass window in the shape of a regular octagon. the octagon must fit inside an square space. determine the length of each side of the octagon. round to the nearest hundredth of an inch.
Using an assumed value that the octagon must fit inside an 11 inch square space, tthe length of each side of the octagon would be 8.23 inches.
Since an assumed side of the square is 11 inches
Here, y is the two equal sides of the right-angle triangle
So y + x + y = 11
Using Pythagoras's theorem for the right angle triangle
y² + y² = x²
2y² = x²
y² = (x²)/2
y = x /√2
So substitute the value of y = x /√2 in the equation
x /√2 + x + x /√2 = 11
2x /√2 + x = 11
2x /√2 + x√2 /√2 = 11
x[2/√2 + √2 /√2] = 11
x[(2 + √2) /√2] = 11
x(2 + √2) = 11√2
x = 11√2/(2 + √2)
x = 15.5563/3.4142 = 12.1421

What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
In order to determine the total cost, we would add all of the costs incurred by Tiny family as follows:
Total cost = 1.3 × 10⁻⁵ + 2.1 × 10⁻⁵ + 7.6 × 10⁻⁶
Total cost = (1.3 + 2.1) × 10⁻⁵ + 7.6 × 10⁻⁶
Total cost = 3.4 × 10⁻⁵ + 7.6 × 10⁻⁶
Total cost = $41.6 × 10⁻⁶
Next, we would calculate the change as follows:
Change = Amount paid - Total cost
Change = $5.0 x 10⁻⁴ - $41.6 × 10⁻⁶

Using algebraic expression and equation, the hotel charge before tax in each city is $5749.60 and $6249.60, respectively.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Let x = hotel charge before tax in the first city
If the hotel charge before tax in the second city was $500 higher than in the first, then
hotel charge before tax in the second city = $500 + x
If the tax in the first city was 6.5% and the tax in the second city was 6% and the total hotel tax paid for the two cities was $748.7, then
x(0.065) + ($500 + x)(0.06) = $748.7
Solving for x,
x(0.065) + ($500 + x)(0.06) = $748.7
0.065x + $30 + 0.06x = $748.7
0.065x + 0.06x = $748.7 - $30
0.125x = $718.7
x = $5749.60
hotel charge before tax in the first city = $5749.60

In the question, It is stated that a photo collage is made by arranging 7 square shaped photos in a row. The arrangement is done in such a way that it forms a rectangle. The total area of the collage is 567 square inches. We have to find out the length of the Collage.
Given that, the photos arranged are of square shape then their length and breadth must be equal. So,
Side of square photo: x
Now, seven photos were arranged, So,
Length of collage = 7x
Breadth of collage = x
We know the Area of the Rectangle is Length*Breadth
Putting Area A = 567, l = 7x, and b = x, we get:
=> Area = l*b
=> 567 = 7x*x
=> 567 = 7x²
=> x² = 81

After how many minutes is the destination reached?
In 400 minutes, it will reach the destination.
What is distance?
Distance is a measurement of how far apart two objects or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in everyday language (e.g. "two counties over"). The term is also frequently used metaphorically to refer to a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between strings of text) or a degree of separation, as spatial thinking is a rich source of conceptual metaphors in human thought (as exemplified by distance between people in a social network). The concept of a metric space is used in mathematics to formalise the majority of these notions of distance, both literal and figurative.
Distance is equal to speed × time. Time is equal Distance/Speed.
we have given, d(t)=340-0.85t
where, t is the time and d(t) is the distance.
when t = 0 we get,
d(t)=340
If we set d(t)=0 we get, 0= 340- 0.85t
add with 0.85t on both side
0.85t=340
t= 340/0.85

In this question, we have been given a rectangular based pyramid PQRST.
A pyramid has height of 10 cm.
We need to find the angle between the line PT and the plane PQRS.
We know that the angle made by triangular plane TPS with the rectangular plane PQRS is same as the angle between the line PT and the plane PQRS.
If we draw a perpendicular through point T and intersects the plane PQRS at point M.
Let R be the midpoint of side PS
Consider a right triangle RMT.
We need to find angle TRM.
Here, MT = 10 cm, MR = 5 cm (1/2 × length of the rectangle)
Consider the tangent of the angle TRM
tan(∠TRM) = TM / RM
tan(∠TRM) = 10 / 5
∠TRM = tan^(-2)[2]

Which ordered pair could you remove from the relation {(–1, 0), (1, 3), (2, 2), (2, 3), (3, 1)} so that it becomes a function
Answer:(3,1)
Step-by-step explanation:
Because you cant have (1,3) and (3,1).
Answer:
(2,3)
or (2,2) if the function does not need to be continuous.
Step-by-step explanation:
For a set of points to be considered a function, it must be true that for every X value, you have only a single Y value solution.
In other words, looking through your points listed, you would remove any point where an X value appears twice with different Y values.
[tex](X,Y)\\(-1,0)\\(1,3)\\(2,2) < -\\(2,3) < -\\(3,1)\\\\[/tex]
Notice the two points with arrows, both have 2 as their X value, but different Y values. Removing either one of them would make this a function. Although, by removing (2,3) the function has the potential to also be continuous, because having two of the same Y value for different X values would cause a piece-wise function which is generally non-continuous.
