Mathematics

Answer:

the answer should be x = -6

Step-by-step explanation:

-9x + 6y = 18

-9x + 6(-6) = 18

-9x - 36 = 18

-9x - 36 + 36 = 18 + 36

-9x = 54

-9x ÷ -9 = 54 ÷ -9

x = -6

Suppose the function f(x) = 2x + 12

First figure out how much it costs to rent seven movies a month. f(7)=2(7) + 12–> 14 + 12–> $26 Now we need to find the difference between 26 and 10. 26 - 10= 16. So Casey needs $16 more to rent 7 movies a month

Please help I’m honestly gonna cry lol

Answer: 2z-15

Step-by-step explanation

Based on the visual image, AD is a line where a point O intersects somewhere on the line. AD is represented as 3z-11, while the segment from AO is represented as z+4.

In order to find the answer, we must subtract the entire line (AD) from AO in order to find the missing segment OD.

AD    -  AO   = OD

(3z-11) -  (z+4) = OD

Distribute the negative sign so it becomes:

(3z-11) -z - 4 = OD

Now combine like terms.

(3z-z) +(- 11 -4)= OD

2z - 15 = OD

And that is your answer!

Answer:

D. 116

Step-by-step explanation:

V=(\frac{1}{3})\pi r^{2}h

V = (1/3)π(4)²(6.9)

V = 36.8π

V ≈ 115.55

<em>Note: You will NEVER use slant height to calculate the area, only to calculate the normal height if unknown. In this problem, we did not use it at all so try not to get confused!</em>
