Answer:
The answer is B
you should still invest in a calculator (:
1/2÷ 3/8=4/3. To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
Maybe it the mixed number form. 2 1/2?
Answer: y = +/- [√x+4) ] / 3
Explanation:
1) To find the inverse of the function y = 9x^2 - 4, exhange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 - 4 → x = 9y^2 - 4
3) Solve for y:
9y^2 = x + 4
y^2 = [x + 4] / 9
y = +/- [ √ (x + 4) ] / 3
X=10 y=5 would be the answers I'm not sure on the equation
