Answer:
5
Step-by-step explanation:
(3,8) (0,4)
X1 = 3 X2 = 0
Y1 = 8 Y2 = 4


Do what's in the parentheses so...
- 3-0= 3
- 8-4= 4
Now plug it in!

Now you are going to finish the parentheses so...
- (3)^2= 9
- (4)^2= 16
Plug that in so that you have this...

Add 9+16 to get...

Then you are going to find the number or numbers that make this a perfect square...

So 5 is your answer
Answer:
x = .5
Step-by-step explanation:
4 / x = 8
4 / .5 = 8
x = .5
For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
The correct answer would be Yes, because the number of wheels in the parking lot is specific to the number of cars in the parking lot.
