Answer:
d. x = 4 and x = –10
Step-by-step explanation:
(x+3)^2=49
Take the square root of each side
sqrt((x+3)^2)=±sqrt(49)
x+3 = ±7
Separate into 2 equations
x+3 = 7 x+3 = -7
Subtract 3 from each side
x+3-3=7-3 x+3-3 = -7-3
x =4 x =-10
Answer:
x=y+v/b
Step-by-step explanation:
So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
