That is correct because it’s a real high school
Answer:
(8, 72)
Step-by-step explanation:
Here we have two separate equations for y: y = 9x and y = 2x + 56.
Equating these equations eliminates y temporarily; we get:
9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.
Then, by the first equation, y = 9(8) = 72.
The solution is (8, 72).
I figured out that number 4 is probably alternate angles. Sorry I couldn't be much help :)
Answer:
See below ~
Step-by-step explanation:
<u>X-intercept(s) : Take y = 0</u>
- 0 = x² - 2
- x = ±√2
- X-intercepts are : (-√2, 0) and (√2, 0)
<u>Y-intercept : Take x = 0</u>
- y = (0)² - 2
- y = -2
- Y-intercept is : (0, -2)
