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
it should be 6x^2-6x if you wrote it right.
Answer:
101,250
Step-by-step explanation:
100,000 * (1 + 5%/(12/3)) = 100,000 * (1.0125) = 101,250
By definition, the area of a square is given by:
A = L ^ 2
Where,
L: side of the square.
Substituting
90 = L ^ 2
Clearing L we have:
L = root (90)
L = 9.486832981 in
Answer:
The side length of the square is:
L = 9.486832981 in
To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
