Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
Hello!
To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.
y=4(0)-1
y=-1
So here, an ordered pair could be (0,-1)
We can try this again for different x-values.
y=4(1)-1
y=3
This gives us the ordered pair (1,3)
y=4(100)-1
y=399
This would give us the ordered pair (100,399)
I hope this helps!
C. 38,200 ft^3
Why you ask? Good question, how you solve volume is l•w•h=v (length•width•height=volume) so it was 60•45.5•14=38,200
Hope this helps!
