-5(r - 6) + 3(-8 + 8r) = -32
STEP 1: Simplify both sides of the equation.

<span><span><span>19r</span>+6</span>=<span>−32</span></span><span><span><span>19r</span>+6</span>=<span>−32
</span></span>
STEP 2: Subtract 6 from both sides.
<span><span><span><span>19r</span>+6</span>−6</span>=<span><span>−32</span>−6</span></span><span><span>19r</span>=<span>−<span>38
STEP 3: Divide both sides by 19.
19r/19 = -38/19
r = -2

Answer:
In order to factor you have to use the distributive property, for the first example you would distribute the 3 to 2x and 1 meaning that you would multiply both 2x and 1 by 3. To distribute negatives you would just pretend that the negative is negative 1 and do the distributive property, for the problems like 4x+2, you would find the gcf or what the two have in common while multiplying and make that the distributor and put what times that equals what the problem is. 4 and 2 have 2 in common because 2x2 is 4 and 2 x 1 is 2. 2 would be outside of the () and then you would put the what times 2 is equal to your original problem so, 2(2+1) to check use the distributive property and you should get your original problem.
Step-by-step explanation:
Replace X with 0 and solve the equation, then replace x with 8 and solve the equation again.
Then find the difference between the 2 answers and divide that by the difference in the 2 X values.:
f(0) = 2(0) + 33(0) -3 = -3
f(8) = 2(8) +33(8) - 3 = 16 + 264 - 3 = 280-3 = 277
Difference: 277 - (-3) = 277+3 = 280
Difference between the X values 8 - 0 = 8
Average rate of change: 280 / 8 = 35
