Set each equation to get Y by its self
Then set the equations equal to each other and solve for X
Easy(:
Answer: its 8
Step-by-step explanation: 5 x is equal too 5 times x and if you do 5 x 8 wich is 40, 40 + 15 =55
Answer:
x = -8 please mark brainliest
Step-by-step explanation:
Pull out like factors :
-x - 8 = -1 • (x + 8)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-8 = 0
Add 8 to both sides of the equation :
-x = 8
Multiply both sides of the equation by (-1) : x = -8
f(x) = x^2 -3x +2
Replace x with 2:
f(2) = x^2 -3(2) +2
f(2) = 4-6 +2
f(2) = 0
g(x) = 4x-5
replace x with -1
g(-1) = 4(-1) -5
g(-1) = -4-5
g(-1) = -9
Now subtract
f(2) - g(-1) = 0 - (-9) = 0+9 = 9
The answer is 9.
