Find the slope of the line through points (4, 6) and (-6,2).

Answers

Answer: Slope = 2/5

Concept:

Here, we need to know how to find the slope.

Slope = (y₂ - y₁) / (x₂ - x₁)

If you are still confused, please refer to the attachment below for a clearer version of the formula

Solve:

Given information

(x₁, y₁) = (-6, 2)

(x₂, y₂) = (4, 6)

Given formula

Slope = (y₂ - y₁) / (x₂ - x₁)

Substitute values into the formula

Slope = (6 - 2) / (4 - (-6))

Simplify values in the parentheses

REMEMBER to change [+, -] signs when there is a [-] sign in front

Slope = 4 / (4 + 6)

Slope = 4 / 10

Divide both numerator and denominator by 2 to get the simplest form

Slope = (4 ÷ 2) / (10 ÷ 2)

Slope = 2/5

Hope this helps!! :)

A.1188
B.1200
C.1220
D.1224​

Answers

Answer:

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

Answer:

It is assumed the question is asking to simplify or factorize:

(a + b)² - a² + b² = a² + 2ab + b² - a² + b² = 2b² + 2ab

This is simplified expression.

Factorizing as follows:

2b² + 2ab = 2b(a + b)

Step-by-step explanation:

[tex](a + b) {}^{2} - {a}^{2} + b {}^{2} [/tex]

a² + 2ab + b² - a² + b²

Cancelling a²

2ab + b² + b²

To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled.You Spent exactly $20 on a taxi which includes the $1 tip you left.
How many miles did you travel?

Answers

Answer:  8 miles

=======================================================

Work Shown:

x = number of miles

2x = cost of traveling x miles, at $2 per mile, without including the $3 fee

2x+3 = total cost now including the $3 entrance fee, without tip

2x+3+1 = total cost plus $1 tip

2x+4 = amount you spent

2x+4 = 20

2x = 20-4

2x = 16

x = 16/2

x = 8

You traveled 8 miles.

Hey there! I'm happy to help!

Let's represent the number of miles traveled with the variable m.

We see that it will cost $2 for every mile, so for if we drive 8 miles, it will cost $16, 9 will be $18, and so forth. So the relationship is that the cost will be double the money, so what we have here is 2×m. In algebra, you can simply write variable multiplication as just putting the numbers next to each other, so 2m will be that part of the equation.

We see that the initial cost of the taxi is $3.

3

We are going to be adding our $2 per mile to this amount (2m).

3+2m

And we will add our $1 tip.

3+2m+1

And this is equal to $20.

3+2m+1=20

We can combine the 3 and the 1 to give us 4.

4+2m=20

So, we see that 2m+4 is equal to 20. If we subtract that four from 20, we will see that 2m is equal to 16.

We remember that our cost from mileage is double the miles, so if 16 is double something, we just divide by two!

16/2=8

So, this means that we traveled 8 miles!

8/15 divided by -0.35 as fraction

Answers

-0.35 = - (35/100) = -7/20
(8/15) / (7/20) = (8/15) * (20/7) = (8*20) / (15*7)
= 160/105 = 32/21

Hi, I'm happy to help!

To solve this problem, we can turn -0.35 into an equivalent fraction.

[tex]\frac{8}{15}[/tex]÷[tex]\frac{-0.35}{1}[/tex]

For division, I like to use the strategy called KFC. This stand for Keep, flip, and change. You keep the first fraction, flip the second, and change the operation.

[tex]\frac{8}{15}[/tex]×[tex]\frac{1}{-0.35}[/tex]

Now we multiply the top by the top and the bottom by the bottom.

[tex]\frac{8}{-5.25}[/tex]

We know that the negative applies to the entire fraction, so we write it like this:

-[tex]\frac{8}{5.25}[/tex]

Kelly works two jobs. She usually works at a retail store for eight hours during the day and is paid $15.23 per hour by the store. In the evening she works at a restaurant as a manager for 8 hours and is paid $24.50 per hour. How much does she make on average per hour for the day?

Answers

Answer:

Kelly makes about $19.87 per hour for the day.

Step-by-step explanation:

Solve for retail store:

121.84

Solve for restaurant:

24.50 × 8

196

Add both of her paychecks:

121.84 + 196

317.84

Divide the total by the total number of hours to find the average per hour:

317.84 ÷ 16

19.865

Round to nearest cent:

19.865 is about 19.87
