Solve the system of equations and choose the correct ordered pair.
Dafna1 [17]

So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

6x-8y=52\\2x+8y=-36

Next, add the two equations together to get 8x=16 . From here you can solve for x.

For this equation, just divide both sides by 8 and your first answer will be x=2

Now that we have the value of x, substitute it into either equation to solve for y:

3*2-4y=26\\6-4y=26\\-4y=20\\y=-5\\\\2*2+8y=-36\\4+8y=-36\\8y=-40\\y=-5

<u>In short, the solution is (2,-5), or A.</u>

The cost of sending an overnight package from Kansas City to Miami is $23.50 for a package weighing up to but not including 1
Dimas [21]

Answer:

For every pound that the package weight increases, the price of sending it increases by $3.80.

Step-by-step explanation:

The coefficient 3.80 multiplies the variable x (package weight), so if x is 1 pound the cost increase $3.80, if x is 2 pound the cost increase 2*3.80 = $7.6, and so on.  Generally speaking, for every pound that the package weight increases the cost increases by $3.80.
