The manager of a restaurant found that the cost to produce 200 cups of coffee is $65.00 , while the cost to produce 250 cups i

PIT_PIT [208]

Answer:

a). y = 0.25x + 15

b). x = 480 cups

Step-by-step explanation:

(a). Let the equation of the linear function passing through a point (x', y') is,

y - y' = m(x - x')

'm' = slope of the line

b = y-intercept

Two points lying on the linear function will be (200, 65) and (250, 77.5).

Slope of the line 'm' = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{77.5-65}{250-200}$

= $\frac{12.5}{50}$

= 0.25

Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,

y - 65 = 0.25(x - 200)

y - 65 = 0.25x - 50

y = 0.25x + 15

(b). For y = $135 we have to calculate the number of cups of coffee produced.

135 = 0.25x + 15

0.25x = 135 - 15

0.25x = 120

x = 480 cups

Therefore, 480 cups of coffee will be produced.

Last week, mallory flew two round trips. They were 3,720 miles and 5,985 miles. Select all of the choices that are good estimate

SVETLANKA909090 [29]

Answer:

Mallory flew in total 10,000 miles, rounded :D

Step-by-step explanation:

Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:

3,720 + 5,985 = 9,705 miles

then, we have to round thefirst digit to the right following this rule

0-4 is rounded down

5-9 is rounded up

now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)

9,705 >>> rounding it up >>> 10,000

Let me know if you have any questions XD

Answer:

a = 1 and b = 14 or a = 14 and b = 1

Step-by-step explanation:

This means that ab = 14 and a + b = 15. Simple guess and check reveals (1, 14) or (14, 1).

At Computer Central, the cost of renting a computer is $45 plus $35 per day. The total cost can be represented by the equation y

Thepotemich [5.8K]

Simple, since your equation is y=35x+45, it's quite simple to see what is the y-intercept.
It's written in y=mx+b form, the b being the y-intercept.

Thus, your y-intercept, is 45.
