Solve for the value of Y using the first equation, 3x-7, and then plug in 3x-7 wherever you see Y, because Y=3x-7. You can find X and then use that value of X and plug it into the equation to solve for Y
Answer:
x + 46

Step-by-step explanation:
<u>Step 1: Define expression</u>
4(-8x + 5) - (-33x - 26)
<u>Step 2: Simplify</u>
- Distribute: -32x + 20 + 33x + 26
- Combine like terms (x): x + 20 + 26
- Combine like terms (Z): x + 46
Answer:
y > 6 or y < -3
Step-by-step explanation:
y² - 3y > 18
Complete the square.
y² - 3y + 9/4 > 18 + 9/4
y² - 3y + 9/4 > 81/4
(y - 3/2)² > 81/4
y - 3/2 > 9/2, or y - 3/2 < -9/2
y > 6 or y < -3
B is the answer because the value of x does not repeat
Answer:
f(e - 9) = 8e - 67
Step-by-step explanation:
To evaluate f(e - 9) substitute x = e - 9 into f(x)
f(e - 9) = 8(e - 9) + 5 = 8e - 72 + 5 = 8e - 67
