Answer:
X^2 -2x-35 =0
Step-by-step explanation:
For equation with solution X= -5 and 7
It implies
X+5 =0 or X-7=0
(X+5)(X-7)=0
x2 -7x + 5x -35=0
X^2-2x-35=0

Answer:
Caleb arrived first 2 hours before Alyssa
Step-by-step explanation:
To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.
Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.
Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.
Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.
He arrived in 210/42 = 5 hours.
Alyssa arrived in 210/30 = 7 hours.
He arrived 2 hours before her.
Answer:
(-3, 2)
Step-by-step explanation:
If we are dealing with vertical movement up/down, we manipulate the x-axis.
If we are dealing with horizontal movement left/right, we manipulate the y-axis.
We are trying to move the point right 4 units (horizontal movement) and down 4 units (vertical movement).
(1, -2) → (1 - 4, -2 + 4) → (-3, 2)
