Answer:
50+50=100
180-100=50
The answer is 40
Step-by-step explanation:
The function is given.
To find :
The input for the function f(x) is (a + 1).
Replace x with (a + 1).
Expand brackets.
Simplifying.
y = 1x + 3, also y = 1x + 4 both of those are parallel
1. y=5-2x
2. -y=5-2x
3.
1. 2x+y=5
y=5-2x
2. 2x-y=5
-y=5-2x
3. x+2y=5
2y=5-x
Distribute the to the .
Rearrange the terms.
Combine the like terms.
Add on both sides.
This statement is false, so the equation has .
