Solve the problem by multiplying first. A clothing store is having a sale on shirts and jeans. Four shirts and two pairs of jean

ella [17]

We will solve this by suing simultaneous equations,

⇒ 5s + 3j = 87

4s + 2j = 64

Multiply the first equation with 4 and the second one with 5, this is to get one of the values equal so that we can cancel them out,

⇒ (5s + 3j = 87) × 4

(4s + 2j = 64) × 5

∴ ⇒ 20s + 12j = 348

20s + 10j = 320

Subtract both the equations. This is how your result (after subtraction) should look like,

⇒ 2j = 28

∴ ⇒ j = $14

Now replace the value of 'j' in one of the original equations,

⇒ 4s + 2(14) = 64

⇒ 4s + 28 = 64

⇒ 4s = 64 - 28

⇒ 4s = 36

∴ ⇒ s = $9

Therefore, one pair of jeans cost $14 and a shirt costs $9

Tell whether each relationship is a function.

Serhud [2]

Answer:

3 is a function.

1 and 2 are not.

Step-by-step explanation:

1 and 2 are not functions because we can draw a vertical line which passes through more than one point on the graphs.

You cant do this on graph 3 so it is a function.
