Answer:
5/21
Step-by-step explanation:
1. 5/7 divided by 3 is the same as 5/7 divided by 3/1
2. when dividing a fraction, multiply by the reciprocal, so it would be 5/7 times 1/3
3. multiply the numerator and denominators, so 5x1 and 3x7
4. the answer is 5/21
hope this helped!
Pick an x-value between the interval givens. I’ll choose “1”. If you sub in one for both f(x) and g(x) you get that f(1) = -1.5 and g(1) = -0.5. Now you can divide f(1) by g(1) to get average rate of change. -1.5/-0.5 = 3.
Ab = (7x-6) → b = (7x-6)/a (1)
bc = (12-2x) → b = (12-2x)/c (2)
Since (1) = (2) → (7x-6)/a = (12-2x)/c OR a/c = (7x-6)/(12-2x) (3)
Multiply both numerators of (3) by the SQUARE of their respective denominators;
(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:
ac = (7x-6)(12x-2x) or ac = -14x² + 96x - 72
