Answer:

Hope this helps, got it from a different website.

Step-by-step explanation:

3x+y=6

3x+y=6 is the new equation that has exactly one solution in common with Elena's equation. .A equation is said to have exactly one solution with this, if the set of equations meet at a point, or have a unique point of intersection. This only happens when the coefficient of x and the coefficient of y are different in the new equation. Solving these pair of equations gives us (1,2) as a unique point.

6x+2y=8

6x+2y=8 is the new equation which has no solutions in common with Elena's equation. An equation is said to have no solutions when the coefficients of both x and y are the same but the constant is different.

6x+2y=12

6x+2y=12 is the equation that has infinitely many solutions in common with Elena's equation. An equation is said to have infinitely many solutions if the result will be 0=0.

You fly from Los Angeles, California, to Miami, Florida. The plane travels a distance of 3,772 kilometers in the air. The flight
Law Incorporation [45]
The average speed of mph would be in 10.058. You would first convert the 6 hours to minutes which would be 60*6 and that equals to 360. Now you add the 15 minutes to add all the minutes together. Now it is 360+15 which is 375. You now get the 3,772 miles and divide it by the number of miles, 3,772/375 and it should be 10.058.

Solve 4−|2x−1| = −3
Vanyuwa [196]
<h3>Given</h3>

... 4 - |2x -1| = -3

<h3>Find</h3>

... x

<h3>Solution</h3>

Add |2x-1|+3

... 7 = |2x-1|

This resolves to two equations:

... -7 = 2x-1

... -6 = 2x

... -3 = x

and ...

... 7 = 2x -1

... 8 = 2x

... 4 = x

The two solutions are x = -3 and x = 4.

Bonifacio works 40 hours per week as a customer service representative. If he made $17,680 last year, how much was he paid per h
GaryK [48]
$8.50 because if he worked 40 hours a week you would multiple that by 52 because there are 52 weeks in a year. From there you would take the total he made and divide it by the hours he worked.
