Step-by-step explanation:
This is the associative property of addition because the grouping of addends does not change the some no matter where you place the numbers in the parenthesis.
Answer:
A. 5.8
Step-by-step explanation:
From the given graph d has two coordinates;
the first coordinates of d = (0, 0)
the second coordinate of d = (-3 , -5), that is x = -3 when traced up and y = -5 when traced horizontal
The distance between the two coordinates = distance of d;

Option A is correct
Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
Answer:
do we have to solve it or what cause I'm confused
