If the three integers are , then we have
We can combine the fractions on the left side:
The formula of a slope:
We have the points (0, -2) and (6, 0).
Substitute:
<h3>Answer: A. 1/3</h3>
Your equation: 4x² - 100 = 0
Factor the left side: (2x + 10) · (2x - 10) = 0
This equation is true if either factor is zero.
-- One factor: 2x + 10 = 0
Divide each side by 2: x + 5 = 0
Subtract 5 from each side: x = -5 .
-- The other factor: 2x - 10 = 0
Divide each side by 2: x + 5 = 0
Add 5 to each side: x = 5 .
Answer:
r=56
Step-by-step explanation:
252= r * 4.5
r * 4.5 = 252
r * 4.5 * 10 = 252 * 10
45r = 2520
r = 56
