Answer: x=4

given equation: 8 - 2x= 5(x-4)

STEP 1: distribute the 5 with ONLY the parenthesis which is (x-4)

so it will be 5x-20 (-20 because 5 x -4= -20)

Now the equation is 8 - 2x= 5x - 20

STEP 2: ADD 20 on both SIDES

8+20= 28

New equation: 28 - 2x= 5x

STEP 3: ADD 2x on both sides 2x+5x= 7x

STEP 4: Now divide 28 by 7

28/7= 4

Therefor x= 4

F(x) = 4x2 – 10x + 2<br> Find f(-7)

eimsori [14]

Answer:

f(-7) = 268

Step-by-step explanation:

f(x) = 4x^2 – 10x + 2

Let x = -7

f(-7) = 4(-7)^2 – 10(-7) + 2

Exponents first

f(-7) = 4(49) – 10(-7) + 2

Multiply

f(-7) = 196 + 70 + 2

f(-7) = 268

Y=x-2+3
I put x-2 because when graphing it's the opposite so it would technically be x+2
Then the +3 for the y chords which go up by 3 ! if this is wrong then try Y= (x-2)+3
