Answer: 2, -1

Step-by-step explanation:

We can substitute y = -2x+3 from the first equation into the second equation.

This results in 4x - 3(-2x+3) =11

We distribute the negative 3 to get 4x + 6x - 9=11

By grouping like terms we get 10x-9=11

Add the 9 to both sides to cancel it out on the left and we get 10x = 20.

This means that x = 2. Now we can substitute x into the original equation. I will use the top one. y=-2(2)+3 is equal to -1, therefore the solution is (2, -1'.

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50 and 52 mi

daser333 [38]

The required probability of giving class period run between 51.5 and 51.75 is 0.125.

The lengths of her classes are uniformly distributed between 50 and 52 minutes.

<h3>What is the probability?</h3>

Probability, can be define as the ratio of favorable events to the n number of total events.

since,

$p(r) = \frac{51.75-51.5}{52-50}$

p(r) = 0.125

Thus, the required probability of class period runs between 51.5 and 51.75 is given by 0.125

the sunshine rental company rents cars for $17 per day plus 50 cents per mole driven the rent me company rents cars for $20 per

forsale [732]

Answer:

21.43 miles

Step-by-step explanation:

Let

x ---> the number of miles

y ---> the total cost of rent a car per day

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

<em>sunshine rental company</em>

The slope is equal to

$m=\$0.50\ per\ mile$

The y-intercept is equal to

$b=\$17$

substitute

$y=0.50x+17$ ----> equation A

<em> rent me company</em>

The slope is equal to

$m=\$0.36\ per\ mile$

The y-intercept is equal to

$b=\$20$

substitute

$y=0.36x+20$ ----> equation B

equate equation A and equation B

$0.50x+17=0.36x+20$

solve for x

$0.50x-0.36x=20-17\\0.14x=3\\x=21.43\ miles$
