I’m pretty sure that it is b
1/4 * x + 1/4 * 4
(the * are multiplication signs)
We have the equations:
x + 3 = 15 and 3y - 1 = 2x - 4
x + 3 = 15 |-3
x = 12
Put the value of x to the second equation:
3y - 1 = 2(12) - 4
3y - 1 = 24 - 4
3y - 1 = 20 |+1
3y = 21 |:3
y = 7
<h3>Answer: x = 12 and y = 7.</h3>
The parabola opens downward
The correct answer is <u>B. 700,000</u>
