What is the solution of this system of equations?y = 3x + 5y = -x + 3​

Mathematics

Viktor [21]3 years ago
3 0

Answer:

The solution is (-1/2, 3  1/2), or (-0.5, 3.5)

Step-by-step explanation:

Seeing that -x + 3 = y (in the second equation), substitute -x + 3 for y in the first equation, obtaining:

-x + 3 = 3x + 5

Combining the x terms, we get

3 = 4x + 5

Combining the constants, we get

4x = -2, or x = -1/2

Seeing that -x + 3 = y, substitute -1/2 for x and calculate y:

-(-1/2) + 3 = y = 3  1/2

The solution is (-1/2, 3  1/2), or (-0.5, 3.5)

a parking garage charges $2.50 base free plus an hourly rate of $4.00. If you hve most $12.50 how many parking you can​
snow_lady [41]

Answer: 2.5 hours or 2 hr and 30 min

Step-by-step explanation:

We can set up an equation to find how many hours you can park.

2.5+4x=12.5

The 2.5 comes from the base fee. The 4x is the hourly rate, where x is hours. The 12.5 is the total amount of money you have.

Since we have our equation, we can solve for x.

4x=10

x=2.5

You can park for 2.5 hours, or 2 hours and 30 min.
