Answer: Y=-5x+30
Step-by-step explanation:
First, you have to find the slope of graph so you find the rise over run Y/X. Since the X values are being measured by 1’s, and the Y values are being measure by 5’s, your slope would be -5 (not 5 as the graph line is decreasing therefore it is negative). To find b, you find the Y intercept of the graph (where Y is when X=0) and in this case, the y intercept is 30. So the equation that describes what is occurring in the graph is Y=-5x+30 as a linear equation is written as Y=mx+b. You can check If the equation is correct by substituting the x and y values of a specific coordinate point on the graph. For example: 25= -5(1)+30. This gives you 25=25 so the equation is correct.
Answer:subtract by 4x on each side first
Step-by-step explanation:
When you do so you'll get 5x on the left side of the equal sign and -5 on the right side. Next you would divide by 5 on both sides and this gives you x on the left side and -1 as your answer on the right side.
Answer:
10,000
Step-by-step explanation:
9564
9=thousands
5=hundreds
6=tens
4=ones
the number behind the thousands (5) must be 5 or higher to be able to round up. Because the number in the hundreds place is 5, the 9 can round up to 10, making it ten thousand (10,000).
Divide the paper which is 21 inches (12+9) by 1.5 and you have your answer which is 14
Answer:
X=Y
Step-by-step explanation:
5x-5Y=
+5y=5y
5x=5y
divide both sides by 5
x=y
