Given:
The system of equations is


To find:
The missing value for which the given system of equations have infinitely many solutions.
Solution:
Let the missing value be k.
We have,


Taking all the terms on the left side, the given equations can be rewritten as


The system of equations
and
have infinitely many solutions if

We have,


Now,



On cross multiplication, we get


Therefore, the missing value is -10.
The function is y=x+2 so the slope of this function is 1
Answer:
48m squared
Step-by-step explanation:
- cut the problem in half horizontally
you get two squares one square is 4 by 4 and the other 8 by 4
4 times 4=16 8 times 4=32 32+16=48
the answer is C, I think because parallel lines never touch
