Answer 1

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)

A (I cant say it on here for some reason )water fish tank requires a certain salinity. To reach this requirement, the relationship between gallons of water and pounds of salt needs to be proportional. The relationship can be modeled as a line on the coordinate plane where x represents the number of gallons of water and y represents the number of pounds of salt. If the line passes through the point (5,1.5) , what does that point represent?

Answers

Answer: Represents when the equation is at 5 gallons of water 1.5 pounds of salt is needed to have the correct salinity

Step-by-step explanation:

water drains out of the bathtub at a rate of 5 gallons in 2 1/4 minutes. how much water drains out of the tub each minute?

Answers

Answer:

[tex]2~2/9[/tex] gallons per minute

Step-by-step explanation:

If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.

We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!

The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].

So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.

The quantity of water that drains out of the tub each minute is 2.23 gallons.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.

2¹/₄ minuts = 5 gallons

1 minute = 5 / 2¹/₄

1 minute = 5 /2.25

1 minute = 2.23 gallons

Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?

Answers

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.
