Answer:
Multiply the first equation by 3 and multiply the second equation by -2.
This is justified by the multiplication property of equality
Step-by-step explanation:
we have
----> first equation
----> second equation
step 1
Multiple the first equation by 3 both sides
-----> by multiplication property of equality
----> new first equation
step 2
Multiple the second equation by -2 both sides
-----> by multiplication property of equality
----> new second equation
step 3
Solve the system of equations by elimination
Adds new first equation and new second equation
Find the value of x
substitute the value of y in any equation and solve for x
The solution is the point 
therefore
Multiply the first equation by 3 and multiply the second equation by -2.
This is justified by the multiplication property of equality
Answer:
The first picture's answer would be (6, 21)
Step-by-step explanation:
You have to find the points on the 8th and the 9th day, and then you would add them together, and then divide by two finding the average, which would be 24 and 18, so when added, you get 42, divided by 2 you get 21. You look on the graph for the point with 21, and you find it is on 6.
Answer:
X = 14.48528137
Step-by-step explanation:
- ADD 72 TO BOTH SIDES
- SQUARE ROOT 72
- ADD 6
- X = 14.48528137
Answer:
2.5; 2.5
Step-by-step explanation:
slope m = (y2-y1)/(x2-x1) (or use the graph and count rise over run)
m = (10-5)/(4-2) = 5/2 or 2.5
The slope of the line is 2.5. This means that 2.5 mm of rain falls every hour
