The rate of change of a graph is given by the y value divided by the x value.
Given that the y-axis is labelled cost (dollars) and that the x-axis is labelled lawns mowed.
Therefore, the rate of change represents the cost per lawn mowed.
Answer:
10.3
Step-by-step explanation:
As we move from (-3,-6) to (2,3), x increases by 5 (this is the horizontal distance between (2,3) and (-3,-6) ) and y decreases by 9 (vertical distance).
We apply the Pythagorean Theorem here:
d^2 = x^2 + y^2, or
d^2 = (5)^2 + (-9)^2 = 25 + 81 = 106
Thus, the distance between (2,3) and (-3,-6) is d = sqrt(106), or approx.
10.3.
To find that divide 32 by 40 and multiply by 100 so
32/40 *100% =80%
Therefore 32 is 80 percent of 40
Answer:
B= 70, C= 50
Step-by-step explanation:
120=15x+5+22x+4
120=37x+9
111=37x
X=3
C: 15×3+5=50
B: 22×3 +4= 70
