Answer:
G = -4x - 4
x = -1
Step-by-step explanation:
step 1: flip your equation and turn G into zero
ex: -4x - 4 = 0
step 2: add 4 to both sides
ex: -4x - 4 + 4 = 0 + 4 (-4x = 4)
step 3: divide both sides by -4
ex: -4x/-4 = 4/-4 (x = -1)
step 4: plug -1 into x then solve to check your answer
ex: -4(-1) - 4 = 0
4 - 4 = 0
0 = 0 (when this says 0 = 0 then that means your answer is always true)
Answer:
d= 90 degrees
e= 99 degrees
f= 81 degrees
Step-by-step explanation:
To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees

9e + -7 = 7e + -11
Reorder the terms:
-7 + 9e = 7e + -11
Reorder the terms:
-7 + 9e = -11 + 7e
Solving
-7 + 9e = -11 + 7e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation.
-7 + 9e + -7e = -11 + 7e + -7e
Combine like terms: 9e + -7e = 2e
-7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0
-7 + 2e = -11 + 0
-7 + 2e = -11
Add '7' to each side of the equation.

2e = -4
Divide each side by '2'.
e = -2

e = -2</span>
The answer is b. The others don’t make sense
