Step-by-step explanation:
x^2 + 2y^2
Let x=3 and y =2
3^2 + 2 ( 2)^2
Exponents first
9 + 2* 4
Then multiply
9+8
Then add
17
Answer:
Step-by-step explanation:
Let’s start seeing what happens to the left. It stops before x = -1, but it continues to do down
so as x approaches -1, y approaches -oo
Now we have to see what happens to the right. In the case the graph doesn’t stop and it keeps to go up
so as x approaches oo, y approaches oo
First, you need to substitute the value of x in all of the x spots.
2x+3
2(3)+3. Us PEMDAS to solve the problem.

Answer:
KL = 10
Step-by-step explanation:
JK + KL = JL
2x – 2 + x – 9 = 2x + 8
Combine like terms
3x -11 = 2x+8
Subtract 2x from each side
3x-2x -11 = 2x+8-2x
x-11 = 8
Add 11 to each side
x-11+11 = 8+11
x = 19
KL = x – 9
= 19-9
= 10
