Answer:
x=-2
Step-by-step explanation:
step 1 -5x-1-5=4
step 2 -5x-6=4
step 3 -5x=10 cause you add 6 on both sides
step 4 and then divide both sides by -5 to get x=-2
x= -2
-0.2(25x+5)-5 = 4
We move all terms to the left:
-0.2(25x+5)-5-(4) = 0
We add all the numbers together, and all the variables
-0.2(25x+5)-9 = 0
We multiply parentheses
-5x-1-9 = 0
-5x-10 = 0
We move all terms containing x to the left, all other terms to the right
-5x= 10
x= 10/-5
The intersection is when both functions have same coordinates
Substitute to get
The y- coordinate is
So the intersection point is (1, 14)
