Answer: D. contradicted the claims of supply-side economists and the Laffer Curve
Step-by-step explanation: In 1993 the federal government boosted income tax rates. The change in tax revenue that occurred in the seven years that followed: contradicted the claims of supply-side economists and the Laffer Curve.
Let the first number be 'x' and the second number is 'y'
Equation 1: x + y = 52
Equation 2: x - y = 38
Rearranging equation 2 to make either x or y the subject
x = 38 + y
Substituting x = 38 + y into equation 1
x + y = 52
(38+y) + y = 52
38 + 2y = 52
2y = 52 - 38
2y = 14
y = 7
Substitute y = 7 into either equation 1 or equation 2 to find x
x + y = 52
x + 7 = 52
x = 52 - 7
x = 45
x = 45
y = 7
Answer:
that puts the solution in the form ...
variable is ...
Step-by-step explanation:
It isn't always.
__
Often, we like to have a solution be in the form ...
variable is ...
So, for an inequality, that puts the variable on the left:
x > 3
y < 27
__
Personally, I like to see the answer in a form that has the variable and its values in the same relation as on a number line. This means, my preferred inequality symbols are < or ≤, since those have the smaller numbers on the left. I would write the first example above as ...
3 < x
showing that the shaded portion of the number line (representing possible values of the variable) is to the right of the open circle at 3. For me, it is more mental effort to translate x > 3 to the same image.

I DONT UNDERSTAND YOUR LANGUAGE IM SORRY ILL TRY TO TRANSLATE
Answer:
C. (-2,4)
Step-by-step explanation:
We have been given a function 
and we are asked to find the vertex of our absolute value function.
The rules for the translation of a function are as follows:
Upon comparing our absolute function with above transformations we can see that our function is shifted to two units right of the origin(0,0) so x coordinate of our absolute function will be -2.
Our function is shifted upward from origin by 4 units, therefore, y-coordinate of our absolute value function will be 4.
Therefore, the vertex of our absolute value function will be on point (-2,4) and option C is the correct choice.
