Exponent rule added:
12xx^2 -9x^2
rewrite 9 as 3 x 3, rewrite 12 as 3 x 4
3 * 4xx^2 - 3 * 3x^2 ( * is multiply)
factor common terms:
3x^2(4x-3) - answer.
Answer:
Step-by-step explanation:
- 2(4 - 1/3u) = - u + 2
- 8 - 2/3u = - u + 2
- u - 2/3u = 2 - 8
- 1/3u = -6
- u = -6*3
- u = -18
I assume that the equation is supposedly written as, y = (76)(1.013^x). This means that the population of the United States increases by 1.3% every year. If we substitute 0 to the value of x,
y = 76(1.013^0) = 76(1) = 76
I assume that the unit for y in the equation is million. Therefore, the answer is letter B. 76 million.
