Answer:
25%
Step-by-step explanation:
The formula to find percent increase is 
. We're given the initial value as 120 and the final value as 150.
Therefore, the percent increase is 25%.
When exponents are separated by a parenthesis it means you need to add them. Because the parenthesis is around the entire number then you raise everything inside the parenthesis to the outside exponent. Then anything raised by 0 as an exponent is automatically 1.
You think of this visually as 3a*3a*3a= 27a^9 is your answer
I believe the answer is 4.
The given point is (0,-12).
It is required to tell whether the point is an x-intercept or a y-intercept.
Recall that the first coordinate of a coordinate point represents the x-coordinate, while the second coordinate represents the y-coordinate.
The x-intercept is the point where the y-coordinate is zero.
The y-intercept is the point where the x-coordinate is zero.
Notice that the given point has an x-coordinate of zero; this means that the given point is a y-intercept.
The point is a y-intercept.
Answer:
1
Step-by-step explanation:
Let x represent the number. The given relation is ...
x² +(x+3)² = 17
2x² +6x +9 = 17 . . . . simplify
x² +3x -4 = 0 . . . . . . subtract 17 and divide by 2
(x +4)(x -1) = 0 . . . . . factor
The solutions make these factors zero: -4 and +1. The positive solution is 1.
The number is 1.
