Answer:
A) x = .9y
B) x + .9y = .038
Substituting A) into B)
.9y + .9y = .038
1.8y = .038
y = .038 / 1.8
y = 0.0211111111
From equation A)
x = .038 -.9*.02111111111111111111111
x = .038 -.019
x = .019
CHECK
x * .9 = .019
.019 + .9 * .021111111111111 = .019 + .019 = .038

Answer:

Step-by-step explanation:
Recall the formula:

We apply this formula to simplify 
This implies that:



This simplifies to


C
Because the graph of the line is y = 2x + 2
The graph is shaded above the line, so we want y values above the line and since it is shaded in (red and not dashed), we want the values above and on the line (aka greater than or equal to SIGN)
