Substitute into second equation:
x+3=2x-3
put variables on one side:
3x=6
x=2
Substitute to find y:
y=2+3
y=5
So (x, y) = (2, 5)
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
Answer: 22
Step-by-step explanation:
The area of the picture =l×b = 20×16=320
The length of the frame is 16
If the width is x ( and it's uniform)
672- 320= 352
Area of the frame = 16× x=352
x=352/16
x = 22
Answer:
He did the equation backward. He did 
, which is wrong.
The actual equation for average rate of change is:
Answer:
Use a line graph with multiple lines.
Step-by-step explanation:
Since line graphs show data over time, and you have multiple people, this is a perfect choice. Put the days or however amount of time on the x axis, and the gallons or a different water amount on the y-axis. Color-code the lines to each family member.
