PLEASE HELP !!!

Help me simplify this expression.

Answer:

Part A  The 4th bubble y= -55x+1630

Part B 1630

Part C 55

Step-by-step explanation:

Part A Use slope to find answer. In this example, points (1,599) and (4,1430).

Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4  which equals 169/-3 and that equals -56.3333333333333333333333.  Since y= -55x+1630 is closer, choose that answer.

Part B use y intercept. The y intercept is 1630

Part C Use the slope -55. It decreases by 55.

Answer:

Sometimes people feel the need to post answers without work. I am greatly saddened by this, or just post answers for the points.

Step-by-step explanation:

I'm going to help, however!

Ok, the mode is the number that appears the most in the data set.

Let's organize this chaos, first. (I hated stats in middle school and elementary.)

6,7,8,9,10,6,7,10,7,6,7,9,7,6

Its best to organize it before finding it!

6,6,6,6,7,7,7,7,7,8,9,9,10,10.

Sevens are most numerous in this data set, with 5 7's!

There's your mode.

Hope this helps!

Answer:

132−15+12

Step-by-step explanation:

Answer:

Step-by-step explanation:

(3x^2-10x+4)+(10x^2-5x+8)

= 3x² - 10x + 4 + 10x² - 5x + 8

= 3x² + 10x² - 10x - 5x + 4 + 8

Answer:

a = 155 degrees

Step-by-step explanation:

A straight line is equal to 180 degrees.

25 + a = 180

   Subtract 25 from both sides.

a = 155

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

As she watches 90 minutes of tv pre day and she watched 10 minutes before school

So minutes left 90-10=80

And 1 episodes contains 20 minutes

So she can watch tv episodes

= 80÷20

=4 (ans)

Note:It is the answer as far as I know. If you have any doubt you can go with others

Answer:

Step-by-step explanation:

Step one:

He charged $25 and spent $6 on gas on Monday.

then he made 25-6= $19 mowing his neighbor's lawn.

the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).

So he mowed his Grandparents yard for $20.

total money saved for Monday and Tuesday is

19+20= $39

Hence he has $39 for mowing both yards

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

x = 90 degrees and y = 43 degrees

Step-by-step explanation:

We have an isosceles triangle here, since the length of AB equals the length of AC.

That also means that angle ABC equals angle ACD = 47 degrees.

The sum of the interior angles of a triangle equals 180.

47 + 47 + 2y = 180

94 + 2y = 180

2y = 86

y = 43 degrees

x + 43 + 47 = 180

x + 90 = 180

x = 90

Answer: true

Step-by-step explanation: I checked it

Answer:

About 19.8

Step-by-step explanation:

First find the side lengths. In this example, 56/4=14

Next use the Pythagorean theorem, to us it, here's the formula a squared plus b squared equals c squared. For this example use 14 squared plus 14 squared which equals 392.

Finally take the square root of 392 because we still need to take the squared out in c. The square root of 392 rounded to the nearest tenth is 19.8.

Answer:

Step-by-step explanation:

Estimates are rough guesses based on current or previous prices. Therefore, it is impossible to conclude whether or not Trenton has actually raised enough money, especially if no actual price for the jackets has been provided. That being said an estimation is usually a close enough representation of the actual value, which would mean that the chances of having raised enough money (if that is what the estimates say) are pretty high.

Answer:

Most likely D, not sure if I am correct, this might not help

Step-by-step explanation:

In order to find the inverse of an equation, we first swap x and y. Then, we solve for y in the new equation.

[tex]y=x^2-5\\x=y^2-5\\x+5=y^2\\±\sqrt{x+5} =y[/tex]

Ignore the A with a caret above it in the front, I don't know why it is there. I am not sure if I am correct, as I have only just completed Algebra 1 so I do not have good knowledge on mathematics.

Answer:

a) x=5

b) x=6

Step-by-step explanation:

a)

3x+7=180-(10x-22)

3x+7=202-10x

13x=195

x=5

b)

11x-3=4x+39

7x=42

x=6

I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.

Answer:

3 5/8 inches of snow per hour

Step-by-step explanation:

29 divided by 8 = 3.625

                             (3 5/8)

if 29 inches for 8 hours, and you need to find how much snow in one hour, you can get 1 hour from 8 hours by doing 8 divided by 8. You  use the same number to find the snow, divide 29 by 8 and you get the rate at which snow builds up.

Hope this wasn’t too confusing ^0^

Answer:

The equation is: y=(x-45)/3 and Beth can ride the bus 118 times.

Step-by-step explanation:

From the information provided, the total cost of riding the bus is equal to the start-up fee plus the cost of each ride for the number of times Beth rides the bus:

x=45+3y, where x is the total cost of riding the bus and y is the number of times Beth rides the bus.

Now, you can solve for y and you can replace x with 400 that is the total amount Beth has:

x=45+3y

y=(x-45)/3

y=(400-45)/3

y=355/3

y=118

According to this, the answer is that the equation is: y=(x-45)/3 and Beth can ride the bus 118 times.

Answer:

A

Step-by-step explanation:

Answer:

The answer is

A.6

Answer:

Steps:

4x - 6 = 34

Add 6 to both sides

4x - 6 + 6 = 34 + 6

Simplify:

4x = 40

Divide both sides by 4

4x/4 = 40/4

Simplify:

x = 10
