Answer:
n=3
Step-by-step explanation:
combine like terms
put 5n to the other side by subtracting it
4n-7=5
no add 7 to other side
4n=12
divide 4 by the 12
n=3
Answer:
It is the second answer
Step-by-step explanation:
The standard form of an ellipse is
x^2/a^2 + y^2/b^2 or x^2/b^2 + y^2/a^2 = 1
If the x is the main axis we use the first form. If the y is the main axis we use the second form. We will use the second form.
our a is 3 and our b is 4
x^2/3^2 + y^2/4^2
Answer:
6
Step-by-step explanation:
Use the given functions to set up and simplify f(-3).
<span>3(x + 1) = −2(x − 1) + 6
3x + 3 = -2x + 2 + 6
5x = 5
x = 1
answer
x = 1</span>
Answer:
Step-by-step explanation:
given f(x)=|x+2 |
after reflection f'(x)=-|x+2|
domain is same.
domain is all real numbers.
