Answer:
20x + 15 = 11
Step-by-step explanation:
First you need to add the like terms:
-7+2=-5
Now you need to expand the brackets:
-5*-4x=20x
-5*-3=15
Now you have 20x + 15 = 11. So if you want you can rearrange the formule to find x.
20x=-4
x= -5
Answer:
The parallel line would be y = -x - 6
Step-by-step explanation:
In order to find the parallel line, we must first start with the slope. The slope of parallel lines must be equal. The first line has a slope of -1. Using this and the new point in slope intercept form, we can solve for the intercept.
y = mx + b
2 = -1(-8) + b
2 = 8 + b
-6 = b
Now we can model the equation using that slope and the intercept.
y = -x - 6
