The questions are asking what percent it changed, not what amount.
Answer:
A
Step-by-step explanation:
5 and 7 are both common factors of 35 and 40
Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.
This leaves A and B. Looking at the equation the difference between the two are the + and -
Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer
Answer:
(0,-7)
Step-by-step explanation:
In this question, we need to find an ordered pair of (x,y)
First we need to solve the equation for Y. It will be:
y-3=5(x-2)
y=5x-10 +3
y= 5x -7
Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be
y= 5x-7
y= 5(0) - 7
y=-7
The ordered pair will be: (0,-7)
