emily and andy each go to a hardware store to buy wire. The table shows the cost y in dollars for x inches of the wire they need. emily needs 21 feet of the wire. andy needs 13 yards of the wire. How much will each of them spend for​ wire?

Answers

Hi! So Emily will spend $15.12. Andy will spend $9.36. When you divide y by x you get a constant. Which in this case is how much a inch of wire costs which is $0.06. Then since you are given Emily and Andy’s lengths in feet you need to convert to inches. Which give you 252” for Emily and 156” for Andy. You then multiply each those lengths by the constant, and you get your answers. Hope this helps some!

The equation that represents the cost of the wire for a certain length will be y = (3 / 50)x.

What is a line passing through two points?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

Emily and andy each go to a home improvement shop to purchase wire. The table shows the expense y in dollars for x crawls of the wire they need.

Take two points from the table, then we have

(120, 7.2) and (125, 7.5)

Then the equation of the line is given as,

(y - 7.2) = [(7.5 - 7.2) / (125 - 120)](x - 120)

y - 7.2 = (3/50)(x - 120)

y - 7.2 = (3/50)x - 7.2

y = (3 / 50)x

The equation that represents the cost of the wire for a certain length will be y = (3 / 50)x.

Assuming these are all different questions,

1. -15 is colder

2. -10 is closer than -8

3. -18

4. -10 feet

5. Not sure what you are asking, but possibly -300

-11 degrees is warmer than -15 degrees, -10 feet is closer than -8, the temperature is -2, the divers' elevation is 10 feet of elevation, and the whale goes 600 feet in all to breath, & to feed.
