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?
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.
If a= -5, what is the value of a^2-4/a+2
Answer:
-7
Step-by-step explanation: When a= 5, let's substitute all a's with 5 in the expression:
[tex]\frac{a^{2}-4 }{a+2}\\\frac{(-5)^{2}-4 }{-5+2}\\\\\frac{25-4}{-3}\\\frac{21}{-3} \\= -7[/tex]
(-6a^4b^3)^2(-2ab^5)
Answer:
[tex]-72a^{9}b^{11}[/tex]

Solve the equation for x.
-7(x - 2) + 5(3 - x) = 4x - 3
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

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