Answer:
<h2>x = 1</h2>
Step-by-step explanation:
![-2+4(-x+4)=10\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\-2+(4)(-x)+(4)(4)=10\\\\-2-4x+16=10\qquad\text{combine like terms}\\\\-4x+(-2+16)=10\\\\-4x+14=10\qquad\text{subtract 14 from both sides}\\\\-4x+14-14=10-14\\\\-4x=-4\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4x}{-4}=\dfrac{-4}{-4}\\\\x=1](https://tex.z-dn.net/?f=-2%2B4%28-x%2B4%29%3D10%5Cqquad%5Ctext%7Buse%20the%20distributive%20property%3A%7D%5C%20a%28b%2Bc%29%3Dab%2Bac%5C%5C%5C%5C-2%2B%284%29%28-x%29%2B%284%29%284%29%3D10%5C%5C%5C%5C-2-4x%2B16%3D10%5Cqquad%5Ctext%7Bcombine%20like%20terms%7D%5C%5C%5C%5C-4x%2B%28-2%2B16%29%3D10%5C%5C%5C%5C-4x%2B14%3D10%5Cqquad%5Ctext%7Bsubtract%2014%20from%20both%20sides%7D%5C%5C%5C%5C-4x%2B14-14%3D10-14%5C%5C%5C%5C-4x%3D-4%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%20%28-4%29%7D%5C%5C%5C%5C%5Cdfrac%7B-4x%7D%7B-4%7D%3D%5Cdfrac%7B-4%7D%7B-4%7D%5C%5C%5C%5Cx%3D1)

Step-by-step explanation:
<u>Step 1: Define</u>
d(x) = 5x - 12
d(-4) is x = -4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: d(-4) = 5(-4) - 12
- Multiply: d(-4) = -20 - 12
- Subtract: d(-4) = -32
Answer:
15

Answer:
13
Step-by-step explanation:
add 3/4 and 3/4 to get 6/4 then get 1/2 times the bottom and the top but 2 to get 2/4 so then do 6/4 - 2/4 to get 4/4 or 1
add 10,8 to get 18 then subtract 6 to get 12 then all the 1 and you get your answer. Hope this helped
