For h(x) = -7x + 10, x =1
For r(x) = 4/5x+ 7 , x = -15
Step-by-step explanation:
in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values
So,
<u>h(x) = -7x + 10; h(x) = 3</u>

Dividing both sides by -7

<u>r(x) =  4/5x+7; r(x) = -5</u>

Answer:
y = 4/5x-18/5
Step-by-step explanation:
First we find the slope from the given points (-3,-6) (2,-2)
m = (y2-y1)/(x2-x1)
m = (-2 - -6)/(2 - -3)
    (-2+6)/( 2+3)
   4/5
The slope intercept form of an equation is 
y = mx +b  where m is the slope and b is the y intercept
y = 4/5 x +b
Substitute a point into the equation to find b
-6= 4/5(-3) +b
-6= -12/5 +b
Add 12/5 to each side
-6 +12/5 = -12/5 +12/5 +b
Get a common denominator
-30/5 + 12/5 = b
-18/5 =b
The equation is 
y = 4/5x-18/5

The factors for given equation f(x)= .
.
- (x-1) - No
- (x-3) - No
- (x+3) - Yes
- (x-5) - Yes
- (x+5) - Yes
<u>Step-by-step explanation:</u>
The given equation is f(x)= .
 .
Add 0 at the end of the equation.
 = 0.
 = 0.
Let us group the given equation,
 =0.
 =0.
⇒ Group 1:  .
 .
Group 2:  .
 .
Pull out factor from each group,
⇒ Group 1:  .
.
Group 2: (x+3) (-25).
Join the two group since both (x+3) is common in both groups.
 =0.
 =0.
One of the factor is (x+3).
Other factors are solved by the formula,  .
 .
 = (x+5) (x-5) .
 = (x+5) (x-5) .
The other factors are (x+5) and (x-5).
