Answer:
-1/20
Step-by-step explanation:
For a graph like this you should make the gallons of gas on y-axis and the miles driven on the x-axis.
To find slope the formula is (y2-y1)/(x2-x1)
So in this case it is 2-4/40-0
-2/40
This reduces to -1/20
Answer:
<u>A (10,3)</u>
Step-by-step explanation:
Y<-60
hope this helps and good luck;)
I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be B

X = y - 3 (equation 1)
2x + y = 12 (equation 2)
Substitute equation 1 into equation 2, replacing every x value with equation 1
2(y - 3) + y = 12
Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)
Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3
Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12
Therefore, x = 3 and y = 6
