Answer:
Step-by-step explanation:
hello :
y= x² + x + 1 ....(*)
and
y= -x - 2....(**)
(**)-(*) : 0 = (x²+x+1) -(-x-2)
x²+2x+3 = 0
(x²+2x+1)+2 = 0
(x+1)² = -2 ...... no solutions in R
Answer:
40
Step-by-step explanation:
If Whitney was driving x speed, her mother was driving x+5. Multiply that by the distance each traveled, and you have an equation that looks like this:
8(x+5) = 7(x)
Simplify it and you get:
8x + 40 = 7x
Now solve regularly:
8x-8x + 40 = 8x - 7x
40 = 1x
40 = x
Whitney's speed: 40
Her mother's speed: 45
