Answer:
E, D
Step-by-step explanation:
rate of change is the slope
slope is change in y over change in x
the slope of the graph is (3/2)
E has a slope of 1/2 which is less than 3/2
D has a slope of 1 which is also less than 3/2
Answer:
$2.72
Step-by-step explanation:
If the price decreased by 20%, the final price will be 100% - 20% = 80% of the inicial price.
So, we can write the ratio box:
Old value New value
Percent value: 100% 80%
Value: $3.40 X
Then we can solve with a rule of three:
100% -> $3.40
80% -> X
X = 0.8 * 3.4 = $2.72
Answer:
5.64
Step-by-step explanation:
Answer:
x = (18 + 3y)/2 y = (18 - 2x)/3
Step-by-step explanation:
For whichever variable you want to solve for, isolate it on one side. For example, if you want to solve for x, first add 3y to each side.
2x = 18 + 3y
Then, divide everything by two.
x = (18 + 3y)/2
