Shantelle wants to rent a midsize car for one day.Value rent a car charges $20 a day plus 0.20 per mile,and best rent a car char

tatyana61 [14]

Answer:

See answers to parts a and b below.

Step-by-step explanation:

A. Value: y=20+.20x

Best Rent y=30+.10x

B. 20+.20x=30+.10x make equations equal each other by subbing y values.

.10x=10 simplify equation

x=100

check answers by subbing 100 for x in each equation.

y=20+.20(100)

y=20+20

y=40

y=30+.10(100)

y=30+10

y=40

Both equations equal 40, so 100 is the correct number of miles for when Value equals Best Rent.

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.

Andrew [12]

Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as $\frac{y_2-y_1}{x_2-x_1}$ . Plugging in the following values would provide you with:

$\frac{(r)-(-5)}{(5)-(2)} =2$

$\frac{r + 5}{3} = 2$

$r + 5 = 6$

$r = 1$

Hope it helps :) and let me know if you want me to elaborate on anything.

Peggy is thinking of a number such that when twice the number is added to three times one more than the number she gets the same

mars1129 [50]

Answer:

-7

Step-by-step explanation:

Lets assume the number Peggy is thinking of be "x".

Now as given, when twice the number is added to three times one more than the number. We can write it as

∴ $2x+3(x+1)$ --- Equation 1

Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.

∴ $4(x-1)$ -- equation 2

Next, we can equate both the equation 1 and 2 as it is given that result is same.

$2x+3(x+1)= 4(x-1)$

Let´s distribute 3 into $(x+1)$ and 4 into $(x-1)$

⇒ $2x+3x+3=4x-4$

⇒ $5x+3=4x-4$

Subtract both side by 4x and 3

∴ $x=-7$

∴ Peggy was thinking of -7
