Answer:

(-1/2, 3)

Explaination:

Multiply the second equation by 2, then add the equations together.

(4x-y=-5)

2(-2x+3y=10)

Becomes:

4x-y=-5

-4x+6y=20

Then add the equations to eliminate x.

5y=15

then solve 5y-15 for y. (Divide both sides by 5)

5y/5 = 15/5

y= 3

Okay, now we have found y where going to plug it in an equation to solve for x

Going to chosse equation : 4x-y=-5

Subsitue 3 for y in 4x - y = - 5

4x - 3 = -5

( Add 3 to both sides)

4x - 3 + 3 = - 5 + 3

4x = -2

(Divide both sides by 4 )

4x/4 = -2/4

x= -1/2

Sam is an artist, and he wants to purchase frames to display his work at home. He wants to frame no fewer than 10 of his pieces,
Amiraneli [1.4K]

Answer:

The option D) 24x+18y=\dollar 225 and x+y^210 is correct

Step-by-step explanation:

Given that Sam is an artist, and he wants to purchase frames to display his work at home.

He wants to frame no fewer than 10 of his pieces, and he can spend a maximum of  $225. Large frames cost $24, and medium frames cost $18.

<h3>To find the system of inequalities can Sam use to determine the number of large frames, x, and medium frames, y, that he can purchase to meet his needs :</h3>

Let x be the large frames cost

Therefore x=\dollar 24

Let y be the medium frames cost

Therefore y=\dollar 18

Sam's Spend amount is \dollar 225

We can write the system of the given condition by

24x+18y=\dollar 225

x+y^210

<h3>Therefore the option D) 24x+18y=\dollar 225 and  x+y^210 is correct</h3>
