Answer
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 180 y = 180 - x
.60x + .85y = .75(180)
.60x + .85y = 135 Multiply both sides of the equation by 100 to remove the decimal points.
60x + 85y = 13500
60x + 85(180 - x) = 13500
60x + 15300 - 85x = 13500
-25x = -1800
x = 72ounces
y = 180 - 72
y = 108 ounces
-1x/-1 = 9/-1
the answer will be x =-9
Answer:
C
Step-by-step explanation:
Rate of change is the slope
Function A:
Slope = change in y/Change in x
= (9-3)/(3-0) = 6/3 = 2
Function B:
Clearly the slope is 3
(y = mx + c, m is the slope)
Rate of change of B is more than A
Answer:
3x - x + 3
