Answer:
X=16
Step-by-step explanation:
according to the diagram above in the attached file
(8x-8)=(7x+8)
8x-7x=8+8
X=16
She would get 4 dollars back because 15 times 4 is 60 and 18 tomes 2 is 36 add them and you get 96 subtract 96 from 100 and 4
Since ∠1 is 63 than ∠2 is 63 too because they are alternate interior. To find ∠3 you subtract 180 by the measure of ∠2 because both of these angles create a straight line.
180 - 63 = ∠3
117 = ∠3
Hope this helps :)

Answer:
Real values of x where x < -1
Step-by-step explanation:
Above the x-axis, the function is positive.
The function is decreasing when the gradient is negative.
The function has a positive

coefficient, therefore the vertex is a local minimum;
This means the gradients are negative before the vertex and positive after it;
To meet the conditions therefore, the function must be before the vertex and above the x-axis;
This will be anywhere before the x-intercept at x = -1;
Hence it is when x < -1.
