-5y-50
Answer:
(0,-9)
Step-by-step explanation:
The image of a point
over a line
is given by the co-ordinate rule:
→ 
So, when we reflect a point over the line
, the x co-ordinate and y co-ordinate change their places.
Here,
is
. So, from the above rule, after reflection over the line
, the image has the following co-ordinates:

Answer:
Communative: 12 x 5= 5 x 12 Associative: (5) + 6 = (8) + 3 Identity: 5 x 1= 5
Step-by-step explanation:
The first one is 21.93 rounded up to 22.
The answer for the first box is 90
Why? Because this is from the expression 90x+1500. The 90x means the slope is 90. So each time x goes up by 1, the value of y goes up by 90
----------------------------
The answer to the second box is 1500
If you were to plug in x = 0, then
y = 90x+1500
y = 90*0+1500
y = 1500
So he earns $1500 for selling 0 copies
