Answer:
-3x+y should not change as it is parallel what should change is the result as you know x = 2 & y = 5 so the result is -3 × 2 + 5 = -1
There will be one solution. To solve that:
1. Get the y alone by switching the places.
6x+y=2 > y=2-6x
-18x+3y=12 > 3y=12-18x > Then divide 3 on each number > y=4-6x
After doing that, you can solve this in graphing or algebra way.
Ima do the algebra way:
SO we have 2 system of equations. Now pick one equestion.
I will pick, y=2-6x. Now Ima replace the Y with the other equation y=4-6x >
4-6x=2-6x.
Now solve. And get > 0 aka Infinite Solution.
Answer:
75
Step-by-step explanation:
3×(5) squared becomes 3× 25=75
Answer:
Step-by-step explanation:
Given
Length is increasing at the rate of 
Width is decreasing at the rate of 
Area is given by
So rate of area is
So, area is changing at the rate of
n=5
Proof:
(n-1)(n+3)=32 Now, substitute n with 5
(5-1)(5+3)
(4)(8)
=32
