1. it helps you by being the first number you use to divide
2 you can multiply the quotient and dividend to check your answer so you can check if the quotient is right, to see if its right it should equal the divisor.

Answer:
m=0
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
- vertical scaling by a factor of -4
- horizontal translation 5 units left
- vertical translation 11 units up
Step-by-step explanation:
We notice that the multiplier of the squared term in f(x) is 0.5; in g(x), it is -2, so is a factor of -4 times that in f(x).
If we scale f(x) by a factor of -4, we get ...
-4f(x) = -2(x -2)² -12
In order for the squared quantity to be x+3, we have to add 5 to the value that is squared in f(x). That is, x -2 must become x +3. We have to replace x with (x+5) to do that, so ...
(x+5) -2 = x +3
The replacement of x with x+5 amounts to a translation of 5 units to the left.
We note that the added constant after our scaling changes from +3 to -12. Instead, we want it to be -1, so we must add 11 to the scaled function. That translates it upward by 11 units.
The attached graph shows the scaled and translated function g(x):
g(x) = -4f(x +5) +11
Answer:
Kay sold 67 cell phones and Allen sold 50 cell phones.
Step-by-step explanation:
Let k = # cell phones Kay sold and a = # cell phones Allen sold.
k + a = 117
k = 17 + a
So:
(17 + a) + a = 117
2a = 100
a = 50
Plug this back into 2nd equation:
k = 17 + a
k = 17 + 50
k = 67
Kay sold 67 cell phones and Allen sold 50 cell phones.
