When you are multiplying 2 numbers with exponents, you need to add the exponent. When you multiply an exponent with an exponent, you multiply them.
So,
(3^2 x 7^4) ^9
First multiply the base and add exponents = ( 21^6) ^9
= 21 ^6x9
21^54
The same rule applies for variables, just pretend there is an imaginary 1.
Answer:
First one is not possible
Second one is possible, and would be an isocèles triangle
Third one is possible, would be scalene
Last one is not possible

Answer:
function g is positive over (-∞, ∞)
function g has a y-intercept of (0,4)
function g decreasing over the interval (-∞, 0)
Step-by-step explanation:
First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
Answer:
y = -1
Step-by-step explanation:
A horizontal line is of the form
y =
The y coordinate of the point (-2,-1) is -1
The equation is y = -1
