Answer:
it is d took the test
Step-by-step explanation:
1) x² - 13x + 30 = 0
x² ⇒ x * x
-13x ⇒ -10x - 3x
30 ⇒ -10 * -3
(x-10) (x-3) = 0
x - 10 = 0 ⇒ x = 10
x - 3 = 0 ⇒ x = 3
Answer is Choice D:) x = 3 or x = 10
2. P(x) = 480x - 2x²
a) P(100) = 480(100) - 2(100²) = 48,000 - 20,000 = 28,000
b) P(120) = 480(120) - 2(120²) = 57,600 - 28,800 = 28,800
c) P(240) = 480(240) - 2(240²) = 115,200 - 115,200 = 0 THIS IS THE ANSWER.
Answer:
x = 9
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (9, - 8) with x- coordinate 9, thus
x = 9 ← equation of vertical line
