Answer:
5a -4
Step-by-step explanation:
Given
(2a + 3) + (3a - 7) ← remove parenthesis
= 2a + 3 + 3a - 7 ← collect like terms
= (2a + 3a) + (3 - 7)
= 5a + (- 4)
= 5a - 4
Cant see it its too blurry bro rip :(
Answer: The temperature that separates the top 7% with the bottom 93% is 99.12 degrees.
The z-score that corresponds to 93% is about 1.48. If we write the equation for the z-score, we can solve for the missing temperature.
The equation would be:
(x - 98.2) / 0.62 = 1.48
x - 98.2 = 0.9176
x = 99.12 degrees
Two numbers that add up to 2 and multiply to -35
-5 and 7
Rewrite the expression using the above;
<u>(x - 5)(x + 7)</u>
Answer:
m = -1/2
Step-by-step explanation:
Recall that slope = (change in y) / (change in x).
Going from (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and
y decreases by 1. Thus, the slope here is
m = (change in y) / (change in x) = (-1) / 2 = -1 / 2
m = -1/2
