Y intercept is (0,-4)
So the Answer is
Y=3x-4
Answer:
The answer is 4
Step-by-step explanation:
Remove the parentheses
55d + 35 + 15d = 315
Collect the like terms
70d + 35 = 315
Move the constant to the right
70d = 315 - 35
Subtract the numbers
70d = 280
d = 4
Answer:
E. (7,-2)
Step-by-step explanation:
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
