y = −2x + 13


y = 2x − 3


Set the equations to equal and solve for x:

-2x + 13 = 2x -3

Add 2X to each side:

13 = 4x -3

Add 3 to each side:

16 = 4x

Divide both sides by 4:

x = 16/4

x = 4


Now replace x with 4 in one of the equations and solve for y:


y = -2(4) +13

y = -8 +13

y = 5


x = 4 and y = 5 , which is the ordered pair (4,5)

Both numbers are positive values, so the second graph is correct.

Natalka [10]

Answer:

<h2>x < 2</h2>

Step-by-step explanation:

Solving inequalities is easy, you just need to follow the standard rules of algebra. Also, when multiplying or dividing by a negative number, the inequality sign is reversed.

Step 1: Divide by 5

x < 2

Step 2: Check

5(1) < 10

5 < 10✔️

Step 3: Check Again

Since an inequality has multiple solutions, it is important to check at least 2, to determine if the entire range of solutions is true.

5(-6) < 10

-30 < 10✔️

Step 4: Verified Answer

x < 2

I'm always happy to help :)
