Two lines are parallel if they have the same slope. Computing for the slope of line segment ab and line segment cd using m=(y2-y1)/x2-x1):
m of ab=(2-1)/(2-1)=1         m of cd=<span>(4-3)/(4-3)=1
Since line segment ab and line segment cd have the same slope which is 1, then they are said to be parallel. </span>

At a concession​ stand, one hot dog and one hamburger cost ​$3.75 ​; one hot dog and cost ​$12.25 . Find the cost of one hot dog
raketka [301]

The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.

<h3>How to calculate the information?</h3>

Let hotdogs = h

Let hamburger = x

The expression will be:

h + x = 3.25

h + 7x = 12.25

Subtract the functions

6x = 9

x = 1.5

Therefore, hot dogs will be:

= 3.25 - 1.5

= 1.75

Answer:

<em>Sonny's weekly gross salary was $575</em>

Step-by-step explanation:

<u>Equations</u>

Sonny works as a furniture salesman and earns a base weekly salary of $350 plus a 6% commission on sales.

This can be modeled by the function:

E(x)=350+0.06x

Where x dollars are his weekly sales.

We are given the total sales for a week are x=$3750, so his earnings are:

E(3750)=350+0.06*3750=575

Sonny's weekly gross salary was $575

Answer:

Look below

Step-by-step explanation:

1) x = 14, because 14 * 14 = 196

2) x = 3 / 16, because ( 3 / 16 ) * ( 3 / 16 ) = 9 / 256

3) x = 8, because 8 * 8 * 8 = 512

4) x = 4 / 7, because ( 4 / 7 ) * ( 4 / 7 ) * ( 4 / 7 ) = 64 / 343
