Step-by-step explanation:
x-55 =25
x=80
Answer:
20
Step-by-step explanation:
4/7 is the same as 4 divided by 7. When you do that you get a really long decimal, I made sure I was right by using a calculator and multiplying that by 35 to get 20.
Hope that helps and have a great day!
Isolate the variable by dividing each side by factors that don't contain the variable.
x= 13/4 - y/4
If you are solving for x (only)
X = 45/4 - y/4
If you are solving for y (only)
Y= 45- 4x
Answer:
Step-by-step explanation:
It is given that the leading coefficient of the polynomial is 1.
We need to find a polynomial function f of the least degree.
If c is a root of a polynomial then (x-c) is a factor of the polynomial.
The given zeros are -1, 1, -4i, 4i. So,
![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)
Therefore, the required polynomial is .
Yes, this is a function because all the inputs only has one output or every x value only has one y value
