Answer:
at least 450 minutes
Step-by-step explanation:
Find an expression for the cost of each plan as a function of the number of minutes. Set the expressions equal to each other, and solve for the number of minutes.
Let x = number of minutes.
First plan:
cost (in dollars) = 0.21x
Second plan:
cost (in dollars) = 0.11x + 44.95
Set the expressions equal:
0.21x = 0.11x + 44.95
Subtract 0.11x from both sides.
0.1x = 44.95
Divide both sides by 0.1
x = 44.95/0.1
x = 449.5
Since you cannot have a fraction of a minute, the answer is 450 minutes.
Answer:
y = - x + 8
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = -x + b Input Slope
Step 3:
7 = - 1 ( 1 ) + b Input x and y
Step 4:
7 = - 1 + b Multiply
Step 5:
b = 8 Add 1 on both sides
Answer:
y = - x + 8
