Answer:
20 dimes and 2 quarters
Step-by-step explanation:
x = number of dimes
y = number of quarters
minimum is greater than or equal to ≥
x+y ≥16
no more than is less than or equal to ≤ ,
value of dime is $ 0.10
value of quarter is $0.25 so
0.10x + 0.25y ≤ 3.00
Rewrite inequalities in terms of y:
y ≥16 - x
(0.25/0.25)y ≤ (3.00/0.25)-(0.10/0.25)x→
y≤12 - 0.4x
Graph system: see file
Y=1/2x+c
0=1/2 (10)+c
0=5+c
c=-5
the equation is y=1/2x+5
the slope is the same since these two lines are parallel
Answer:
rate of change is -3
A = (9 - 0) / (0 - 3) = 9 / -3 = -3
