Mark, Yolanda, Jaime, and Sharon are four friends who decided to meet each other in Charleston on Friday to tour the city for a

holiday weekend. Each friend had to drive a different distance from their homes. The table shows how far each friend traveled to Charleston and how long it took each to travel there.

Answer:

Mark

Step-by-step explanation:

<u>Concepts + Application</u>

The velocity, in this case, is the speed of each friend's car while traveling to Charleston. To find the speed, we divide the number of miles (aka the distance) by the number of hours. The friend with the greatest quotient is the one who traveled at the highest velocity.

<u>Solution</u>

250 ÷ 5 = 50

240 ÷ 4 = 60

135 ÷ 3 = 45

110 ÷ 2 = 55

As you can see, 60 mph is the greatest velocity, so the person who traveled at the highest velocity to Charleston is Mark.

A sno-cone machine priced at $139 is on sale for 20% off. What is the price of the sno-cone machine after the discount? *
lawyer [7]
So percents are just written as 20% = 0.2 so keep that in mind

139 divided by 0.2 is 95 , which would be the price after the discount :)

You were given the polynomial f(x)=3x^3+13x^2+19x+k and you know that f(-2)=0find k
eduard

Answer:

k = 10

Explanation:

The initial polynomial is:

f(x)=3x^3+13x^2+19x+k

If f(-2) = 0, then when we replace x by -2, the result will be 0. It means that we can write the following equation:

\begin{gathered} f(-2)=3(-2)^3+13(-2)^2+19(-2)+k=0 \\ 3(-2)^3+13(-2)^2+19(-2)+k=0 \end{gathered}

Therefore, we can solve for k as follows:

\begin{gathered} 3(-8)+13(4)+19(-2)+k=0 \\ -24+52-38+k=0 \\ -10+k=0 \\ -10+k+10=0+10 \\ k=10 \end{gathered}

So, the value of k is 10

PLZ HELP AND SHOW YOUR WORK &lt;3333<br><br><br> Substitution.<br><br> 3x+2y=11<br><br> y=5x-1
liraira [26]
Hey there! :D

Substitute y for 5x-1. 

3x+2y=11

y=5x-1

3x+2(5x-1)=11

3x+10x-2=11

13x-2=11

13x=13

x=1

Now, plug that in to find y.

y=5x-1

y=5(1)-1

y=5-1

y=4

(1,4) <== the solution
