7+ (x+5)
You write it exactly how you say it.

7+(x+5) would be the answer because sum means addition and it says x and 5. then it says 7 plus that so you put 7. In reality you wouldn't need parenthesis, but if you want it to match the phrase, you can put it in parenthesis.

The average basketball has a diameter of 9.5 inches. What is the volume of an average basketball?

Elodia [21]

the formula for volume of sphere is 4/3||r^3

diameter=2radius

in the formula we need to have radius but we have been given diameter so we convert diameter to radius

d=2r

r=d/2

9.5÷2

A system of equations consists of a line s of the equation y = x – 5 and a line t that passes through the points (0, 2) and (8,

GenaCL600 [577]

Answer:

$\text{The slope of the line t:}\ m=-\dfrac{3}{4}\\\\\text{The y-intercept of the line t:}\ b=2\\\\\text{The equation of a line t in the slope-intercept form:}\ y=-\dfrac{3}{4}x+2$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (8, -4) and (0, 2) → b = 2.

Calculate the slope:

$m=\dfrac{2-(-4)}{0-8}=\dfrac{6}{-8}=-\dfrac{3}{4}$

Therefore the equation of a line t in the slope-intercept form is:

$y=-\dfrac{3}{4}x+2$
