Answer:
Step-by-step explanation:
In exponent multiplication, if base are same just add the powers.

28x - 2 = 26x + 6
2x = 8
x = 4
The answer should be H= 7.9
Answer:
A) -0.3 of an inch per second
Step-by-step explanation:
You'll have to put (2, 8.4) and (4, 7.8) into the slope formula.
It's represented as (∆y)/(∆x) = m
(y1 + y2)/(x1 + x2) = m
You subtract both y's in the numerator and subtract both x's in the denominator.
Like this:
(8.4-7.8)/(2-4) = m
(0.6)/(-2) = m
-0.3 = m
