Two car rental companies charge an initial rental fee plus a fee per day. The table shows the total costs of renting a car for x days from
Discount Car Rentals. The total costy (in dollars) of renting a car for x days from Pay Less Rentals is represented by the equation
y=25x + 170. Which rental company charges less per day? How many days must you rent a car for the total costs to be the same?

Answers

Answer:

Step-by-step explanation:

Two car rental companies charge an initial rental fee and a fee per day.

Total cost for the company A is given by the equation,

y = 25x + 170

Car A charges $25 per day. [Slope of the line]

Another car rental company B charges as per table attached.

Per day car rental for the company B = [tex]\frac{270-180}{4-2}[/tex]

= [tex]\frac{90}{2}[/tex]

= $45 per day

Therefore, per day rental charged by company A is less.

Let the equation for the car rental by company A is,

y = mx + b

where m = per day rental charged by company A = $21.5

y = 45x + b

One point (2, 180) from the table lies on the equation.

Therefore, 180 = 45(2) + b

b = 180 - 90

b = 90

So the equation will be,

y = 45x + 90

If both the company charge the same after x day of rental,

45x + 90 = 25x + 170

45x - 25x = 170 - 90

20x = 80

x = 4

After 4 days car rentals for both the companies will be same.

Line j passes through points (10, 10) and (1, 3). Line k is parallel to line j. What is the slope of line k?

Answers

Answer:

= (10-3) ÷ (10-1) = 7 ÷9 = 7/9

Step-by-step explanation:

As they are parallel, their slopes are the same. So if we find slope of line j we find slope of line k when we have two points of one line like (x1 , y1) and (x2 , y2) the slope of that line is (y2-y1) ÷ (x2-x1)

11. During an evening out, Dean paid a cab driver $20. He
then spent $25 on dinner and half of his remaining money on a painting. He bought an umbrella for $23.75 and had $42.15 left. How much money did Dean have at the beginning of the weekend?

Answers

Let total amount be x.
Cab - $20
Dinner - $25
Remaining Amount- (x-45)
Hlf of this amount was spent on painitng. So, net cash in hand is (x-45)/2.

out of this cash in hand, he has gt umbrella for 23.75, and balance cash is 42.15.

so, (x-45)/2=23.75+42.15

(x-45)/2=65.9
x-45=131.8
x=176.8

Amount Dean had at the beginning of the weekend = $176.8

Answer:

$176.80

Step-by-step explanation:

$42.12 (what he had left) + 23.75 = 65.90

65.90 (Amount he had after he bought the painting) + 65.90 (The other half of his remaining money he spent on the painting) = 131.80

131.80 + 25 + 20 = 176.80

= $176.80

Solve the equation for x.

-7(x - 2) + 5(3 - x) = 4x - 3

Answers

Answer:

x=2

Step-by-step explanation:

-7x+14+15-5x=4x-3

-12x+29=4x-3

-12x-4x=-29-3

-16x=-32

x=-32/-16

x=2

Answer: x=2

Step-by-step explanation:

Simplify the equation

-12+29= 4x-3

Subtract 29 from both sides

12x=4x-32

Subtract 4x from both sides (Simplify)

-16x=-32

Divide both sides by -16

x=2
