Expand 6(x-8)= x- (8) = help me

maksim [4K]

Answer:

x = 8

Step-by-step explanation:

6(x-8)= x- (8)

6x - 48=x - 8

6x- 48 + 48 = x - 8 + 48

6x = x + 40

6x - x = x + 40 - x

5x = 40

5x/5 = 40/5

x = 8

Write an equation of the line passing through the points (4,6) and (-2, - 18).

olga_2 [115]

Answer:

y = 4x – 10

Step-by-step explanation:

slope formula: $m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

point-slope formula: $y-y_{1}=m\left(x-x_{1}\right)$

Use slope formula and plug in your numbers: $m = \frac{-18-6}{-2-4 }$
Solve for slope $m = 4$
Use the point-slope formula to solve for the equation: $y-6=4\left(x-4\right)$
Solve and find equation: $y=4x-10$

Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!

Given that (-3,7) is on the graph of f(x), find the corresponding point for the function f(x + 5).

Stella [2.4K]

We have that
<span>(-3,7) is on the graph of f(x), find the corresponding point for the function
f(x + 5)

we know that
in the transformation f(x)-------> f(x+5)
the point (x.y) in f(x) becomes a point (x-5,y) in f(x+5)
so
(-3,7)-----------> becomes a point (-3-5,7)------> (-8,7)

the answer is
</span>(-8,7)<span>

</span>
