Answer:
- x² = y + 16
- 4y - 1 = 7x
- (5, 9)
Step-by-step explanation:
Writing equations from words is mostly a matter of understanding what the English words mean.
If the first number is x, then the square of the first number is x². That is said to be equal to the sum of the second number (y) and 16:
x² = y + 16 . . . . the first equation
The wording "the difference of A and B" is usually intended to be interpreted to mean A-B. Here, we have the difference of 4 times the second number (4y) and 1, so ...
4y -1
This is equal to the first number (x) multiplied by 7, so ...
4y -1 = 7x . . . . the second equation

These can be solved a variety of ways. When no method is specified, I like to use a graphing calculator. It shows the only integer solution for this pair of equations is ...
(x, y) = (5, 9)

Find f(-5) by substituting x = -5 in the equation.

Therefore, the answer is f(-5) = 16
Answer:
P'(4, 9)
Step-by-step explanation:
Add the translation vector to the point:
P' = P +(6, 5) = (-2, 4) +(6, 5) = (-2+6, 4+5)
P' = (4, 9)
