Answer:
Top row, third one from left to right
Step-by-step explanation:
Use test points:
when x = 0 , y = 2(0) - 4 = 0 - 4 = -4
(0, -4)
when y = 0, 0 = 2x - 4, 4 = 2x, 2 = x
(2, 0)
Top row, third one from left to right
A teacher writes the following product on the board:
(5x + 2)(x + 4) = 5x^2 +22x +8
Palesa says that 5x^2 +22x + 8 is a factor of 5x +2.
Nune says that 5x+ 2 is divisible by 5x^2 +22x +8.
Who is correct?

Answer:
-7/45
-4/15+1/9 (two negatives make a plus or addition)
least common multiple of 15 and 9 = 45
45 is the denominator
15*3=45 , 9*5 = 45
-4*3 = -12 ,1*5 = 5
-12+5 = -7/45
Answer:
-7/45
Step-by-step explanation:
find lowest common denominator: 45 (9 x 5 = 45, 15 x 3 = 45)
[tex]-\frac{4}{15} = \frac{(4*3)}{(15*3)} =-12/45\\\\\frac{1}{9}=\frac{(1*5)}{(9*5)} =5/45[/tex]
subtracting a negative = addition
[tex]-\frac{12}{45} +\frac{5}{45}\\\\=\frac{-12+5}{45} \\\\=-\frac{7}{45}[/tex]

What is the median of this set of data?
362, 187, 211, 298, 331, 250, 347, 199
Answer:
187, 199, 211, 250, 298, 331, 347, 362
[tex]median = {( \frac{n}{2} + 1) }^{th} \: value \\ = ( \frac{8}{2} + 1) {}^{th} \: value \\ = {5}^{th} \: value \\ median = 298[/tex]
Answer:
The median is the middle number in a set of data when the data is arranged in ascending (this is more common) or descending order. If there are an even number of values in the data set, the median is the arithmetic mean of the two middle numbers. Thus, the median separates the lower and higher half of a data set.
Step-by-step explanation:
ascending order : 187, 199, 211, 250, 298, 331, 347, 362
answer: 250, 298 .

What single decimal multiplier would you use to increase by 5% followed by a 20% increase?
Answer:
The desired single multiplier is 1.26.
Step-by-step explanation:
A 5% increase results in the original amount PLUS 5% of the original amount:
1.05(original amount)
If a 20% increase follows, we must multiply the above 1.05(original amount) by 1.20:
1.20(1.05)(original amount), or (after multiplying), 1.26.
The desired single multiplier is 1.26.

Suppose that the monthly salary can be modeled by the function p(x) = 20,000 + 50x. In the formula, 20,000 represents the base salary, and the person gets an additional $50 for every sale. The variable x represents the number of sales. How many items does the salesperson need to sell to earn $30,000?
Answer:
$50 is the earned for every sales
$30000 is earned for 30000/50=600
He has to made 600 sales to earn 30000
Find the value of x.
Answer:
Step-by-step explanation:
This is a right triangle; so you can use the Pythagorean Theorem ([tex]a^2 + b^2 = c^2[/tex]), where a and b are the lengths of the legs and c is the hypotenuse.
You get: [tex]5^2 + 12^2 = c^2[/tex]
Simplify the expression: [tex]25 + 144 = c^2[/tex]
Combine like terms: [tex]169 = c^2[/tex]
Take the square root of both sides: [tex]\sqrt{169} = \sqrt{c^2}[/tex]
Evaluate: 13 = c
So the answer is letter c ... x = 13

A and B are 2 cylinders that are mathematically similar the area of the cross section for cylinder A is 18cm squared. find out the volume of cylinder b
Answer:
Volume of cylinder B = 720 cm³
Step-by-step explanation:
Given:
A and B are similar cylinder
Height of cylinder B = 10 cm
Height of cylinder A = 5 cm
Area of the cross section for cylinder A = 18 cm²
Find:
Volume of cylinder B
Computation:
Area of the cross section for cylinder B = a
So,
(10/5)² = (a/18)
4 = a/18
Area of the cross section for cylinder B = 72 cm²
Volume of cylinder B = Area of the cross section for cylinder B x Height of cylinder B
Volume of cylinder B = 72 x 10
Volume of cylinder B = 720 cm³

The owner of a smoothie company wants to rent a kiosk in the new mall. He is choosing between two spaces. Both have floor plans shaped like parallelograms. The first space is 12 feet wide and 16 feet long. The second space is 13 feet wide and 15 feet long. Which is the larger space? Explain.
Answer:
The second space (13 feet wide & 15 feet long) is the larger space.
Step-by-step explanation:
According to the question,
Given, The owner of a smoothie company wants to rent a kiosk in the new mall. He is choosing between two spaces. Both have floor plans shaped like parallelograms. The first space is 12 feet wide & 16 feet long ( Rectangle, A Type of Parallelogram).Thus, The Area Of Rectangle = Length x Width ⇒ 12 × 16 ⇔ 192 Feet² .
The second space is 13 feet wide & 15 feet long( Rectangle, A Type of Parallelogram) .Thus, The Area Of Rectangle = Length x Width ⇒ 13 × 15 ⇔ 195 Feet² . Hence it is Clearly Shown here the The second space (13 feet wide & 15 feet long) is the larger space .
Two angle in a triangle equal 120°. What is the measure of the third angle?
a) 60°
b) 70°
c) 80°
d) 90°
e) 120°
Answer:
a) 60, because in every triangle, the angles always add up to 180. there are three angles in a triangle, and you k is two add to 120, so of you and 60 to 120 you get 180
Daisy's mom is 4 times as old as she.The sum of their ages 6 years ago was 28.How is her mother now?
Answer:
32
Step-by-step explanation:
Daisy's mom is 4 times as old as she.
m = 4d
The sum of their ages 6 years ago was 28.
(m - 6) + (d - 6) = 28
Substitute for m = 4d
(4d - 6) + (d - 6) = 28
Combine like terms
5d - 12 = 28
5d = 40
Divide by 5
d = 8
m = 4d
m = 4 * 8
m = 32

(50 points) A diameter of a circle has endpoints P(-10, -2) and Q(4,6)
A. Find the center of the circle
B. Find the radius. if your answer is not an integer, express it in radical form.
C. Write an equation for the circle
Answer:
Step-by-step explanation:
The center of the circle is the midpoint of the two end points of the diameter.
Formula
Center = (x2 + x1)/2 , (y2 + y1)/2
Givens
x2 = 4
x1 = - 10
y2 = 6
y1 = - 2
Solution
Center = (4 - 10)/2, (6 - 2)/2
Center = -6/2 , 4/2
Center = - 3 , 2
So far what you have is
(x+3)^2 + (y - 2)^2 = r^2
Now you have to find the radius.
You can use either of the endpoints to find the radius.
find the distance from (4,6) to (-3,2)
r^2 = ( (x2 - x1)^2 + (y2 - y1)^2 )
x2 = 4
x1 = -3
y2 = 6
y1 = 2
r^2 = ( (4 - -3)^2 + (6 - 2)^2 )
r^2 = ( (7)^2 + 4^2)
r^2 = ( 49 + 16)
r^2 = 65
Ultimate formula is
(x+3)^2 + (y - 2)^2 = 65
The radius is √65 = 8.06

A car collection has ¼ black cars, ⅝ red cars ond 7 white cars. Draw model of the car collection?
answer below.
mark me brainlist
Answer:
Step-by-step explanation: Let the total no of cars in the collection be X
Number of black cars = (1/4)X
Number of red cars = (5/8)X
Number of white cars= 7
Summation of all the cars,
(1/4)X + (5/8)X + 7 = X
X= 56
Therefore,
Number of black cars = (1/4) of 56 = 14
Number of red cars = (5/8) of 56 = 35
Number of white cars = 7
