What is the slope of the line by the equations below? y-9=15 (x-5)

Answers

Answer 1

Answer:

Answer:

Use the slope-intercept form

to find the slope

Step-by-step explanation:

Cuz i know all that

Answer 2

Answer:

To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.

y - 9 = 15(x - 5)

y = 15(x - 5) + 9 (Add 9 to each side)

y = 15x - 15*5 + 9 (Expand 15(x - 5))

y = 15x - 75 + 9

y = 15x - 66

Therefor, the slope of the equation is 15.

A store has thirty-five diet sodas, which is seven times the number of regular sodas they have. How many regular sodas do they have?

Answers

35/7=5 regular sodas

They have 5 regular sodas.

Here is an equation that you can use to solve this problem:
35 = 7 * x

The first step is to use inverse operations and divide both sides by 7, which gives you this.
5 = x

So, the answer is five. Good luck, and if you need any other answers, be sure to tell me!

You pay $2.40 for 3/4 pound of grapes. Your friend buys a pound of grapes at the same time and estimates that he will pay $1.80. What can you say about your friend's estimate?

Answers

Your friend's estimate is wrong because you pay $2.40 for 3/4 pound of grapes, which means 1/4 pound of grapes equals $0.80, you friend wants to any for one pound, so your friend must use 1/4 times 4 equals $0.80 times 4=$3.20 for a pound of grapes

I have one half of a square and i want to divide it one eighth how many pieces would I have

Answers

You will have 4 pieces.

Explanation

Suppose, the number of pieces is $x$

As each piece must be $(1)/(8)$ of a square and you have initially $(1)/(2)$ of a square, so the equation will be.....

$(1)/(8)x= (1)/(2)\n \n x= (1)/(2)*8 = 4$

So, you will have 4 pieces.
