What is the answer to this question ?
Tatiana [17]

Answer:

- 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - \frac{40}{17} ← is in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

Thus the slope of line d is - 1

A phone company offers two monthly plans. In plan A, the customer pays a monthly fee of $35 and then an additional 9 cents per m
lbvjy [14]

Answer:

Lesser than 6.9 minutes

Step-by-step explanation:

Let m represent the number of minutes of phone use with either plan A or plan B.

In plan A, the customer pays a monthly fee of $35 and then an additional 9 cents(9/100 = $0.09) per minute of use. This means that the total cost of m minutes would be

0.09m + 35

In Plan B, the customer pays a monthly fee of $55.70 and then an additional 6 cents(6/100 = $0.06) per minute of use. This means that the total cost of m minutes would be

0.06m + 55.70

Therefore, for the amounts of monthly phone use for which Plan A will cost less than Plan B, it becomes

0.09m + 35 < 0.06m + 55.70

0.09m - 0.06m < 55.70 - 35

0.03m < 20.7

m < 20.7/3

m < 6.9
