Answer:
D
Step-by-step explanation:
To find the rate of increase all you have to do is take one of the data sets to see that every two months its charge time increases by 15 minutes or 7.5 minutes every month.
For every one stamp James has Roy has twice as much. So the ratio would be 1/2
You convert the fractions into 6ths. So 1/3. You would multiply both parts by 2 (top and bottom denominators) and that would be 2/6. 1/2 of 6 is 3/6. So the answer would be 1/6
Answer: y=-2x-3 = x=-1/2y+-3/2
5x = -4+ y = x=1/5y+-4/5
proof:
y=-2x-3 -- Step 1: Flip the equation.
−2x−3=y
Step 2: Add 3 to both sides.
−2x−3+3=y+3
−2x=y+3
Step 3: Divide both sides by -2.
−2x/-2=y+3/-2
5x = -4+ y -- Step 1: Divide both sides by 5.
5x/5=y-4/5
