<u>Answer:</u>
45
<u>Step-by-step explanation:</u>
We are given an equation <em>x - y = 30 </em>which we are to solve for x when the value of y is 15.
To solve this linear equation for x, we just need to substitute the given value of y into the equation to get the value of x.
x - y = 30
x - 15 = 30
x = 30 + 15
x = 45
Therefore, the value of x is 45 when y = 30.
Unfortunately this value is not in the given options but 45 is the correct answer.
First you need to find the other sode length of the desktop and because its a rectangle the two other sides will be equal. you know the area is 15 and to find area you multiply length and width so to get the other side dived 15 by 3 to get 5 and then do 3+3+5+5 which would give you the perimeter = 16
Hiiiiiii sorry Im not sure if u already got it but its
Answer:
2
Step-by-step explanation:
{(-6, -4), (4, -8),(-6,9), (1, -3)}
These ordered pairs are not a function.
-6 has 2 outputs.
The sum function is defined exactly as the sum of the two functions:
So, you simply have to sum the expressions:
