Mathematics

→Answer:

y = -17

→Step-by-step explanation:

Well first off the f(x) in the equation f(x) = 3x + 7 can also be written as y,

y = 3x + 7

So if x is -8 we need to plug it in for x and solve, simple as that :)

y = 3(-8) + 7

y = -24 +7

y = -17

Please help, I have redone this problem a million times and i cant get it right. Time sensitive!!
Advocard [28]

Answer:

D

Step-by-step explanation:

This should be easy one unless you're making silly mistake like forgetting to take reciprocal of \frac{3}{2x}

lets do it:

\frac{x+2}{x-1} ÷ \frac{3}{2x} first: we take the reciprocal of 3/2x now its

\frac{x+2}{x-1} * \frac{2x}{3} now just multiply top and bottom by using distributive method

\frac{2x^2 +4x}{3x-3} this is your answer.

What's the slope of (-4,7)(-2,17)
yaroslaw [1]
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:

m=(y₂-y₁)/(x₂-x₁)

Data:
The points are (-4,7) and (-2,17), then the slope will be:
m=(17-7)/(-2+4)=7/2

Answer: the slope of the line passes through these points would be 7/2
