Answer:

Step-by-step explanation:

Answer:

Which expression represents the area?

Which expression represents the perimeter? 2x squared plus 8x - 2

Step-by-step explanation:

A= LxW

P= L+W+L+W

Answer: the equation will be  y = 5/2x -5

Step-by-step explanation:

First find the slope of the line by finding the change in the y coordinates and diving it by the change in the x coordinates.

(6,10)

(4,5)  

5 - 10 = -5

4 - 6 =  -2

Slope: 5/2

(4,5)

(-2,-10)

-10 - 5 = - 15

-2-4= - 6

-15/-6 = 5/2

Now we know the slope is 2, so use the formula y=mx + b to solve for the y intercept which is b by using one of the given points.

y = mx + b

5 = 5/2(4) + b

5 = 10 + b

b =   -5

Answer: the 2nd one

Step-by-step explanation: because i said so ur the dum one

Answer:

see in the picture, the perimeter of this rectangle is

2( x + 3x) = 8x but the perimeter is 65.6

=> 8x = 65.6

<=> x = 65.6/8

=> x = 8.2

Answer:

3/8

Step-by-step explanation:

Answer:3/4 pretty sure

Answer:

m<1 = 62°

m<2 = 45°

m<3 = 24°

Step-by-step explanation:

Hi!

Let me walk you through it!

The first step is to find angle 1.

Angle 1 is supplementary with the angle 118°

So we do 180° - 118° = 62°

m<1 = 62°

Then we find angle 2.

There are two ways to do this

The sum of interior angles in a triangle is 180°

So we do 180° - (73 + 62°)

Open parenthesis:

180° - 73° - 62° = 45°

You can also use the exterior angle theorem

118° = 73° + m<2

Same to both sides:

45° = m<2

So

m<2 = 45°

Now, using this information, we can find angle measure 3.

Now we look at the big triangle. Again, there are two ways to do this.

First way:

m<1 + 49° + m<2 + m<3 = 180°

Plug in known-values

62° + 49° + 45° + m<3 = 180°

Combine like terms:

156° + m<3 = 180°

Same to both sides:

m<3 = 24°

Second way:

Exterior angle theorem.

118° = m<2 + m<3 + 49°

Plug in known-values:

118° = 45° + m<3 +49°

Combine like terms:

118° = 94° + m<3

Same to both sides:

24° = m<3

So m<3 = 24°

There you go! You just need to take it step-by-step and you can get the answer. Be open-minded, don't just try to go for a certain angle, see what you can do, and work from there. It all comes together at the end.

Let me know if you have any questions, have a good day!

Answer:   (-13xy) + (-5xy) = -18xy

Step-by-step explanation:

well they are both negatives t=so they cant be subtracted from each other instead they are being added

13 + 5= 18

but remeber to add back the negative sign adn the variables

so its -18xy

Answer:

[tex]n + 4.4 = 8.1[/tex]

Step-by-step explanation:

We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.

Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be [tex]n + 4.4[/tex].

Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be [tex]n + 4.4 = 8.1[/tex].

Answer:

[tex]A = (\frac{80}{3},9)[/tex]

[tex]B = (5,2.5)[/tex]

The slope is 0.3

Step-by-step explanation:

Given

[tex]y = 0.3x + 1[/tex]

[tex]A = (-,9)[/tex]

[tex]B = (5,-)[/tex]

Required:

Fill in the gap and calculate the slope

In [tex]A = (-,9)[/tex]

[tex]y = 9[/tex] and x is ??

Substitute 9 for y in [tex]y = 0.3x + 1[/tex]

[tex]9 = 0.3x + 1[/tex]

Collect Like Terms

[tex]0.3x = 9 - 1[/tex]

[tex]0.3x = 8[/tex]

[tex]x = \frac{8}{0.3}[/tex]

[tex]x = \frac{80}{3}[/tex]

So:

[tex]A = (-,9)[/tex]

[tex]A = (\frac{80}{3},9)[/tex]

In [tex]B = (5,-)[/tex]

[tex]x = 5[/tex] and y is ??

Substitute 5 for x in [tex]y = 0.3x + 1[/tex]

[tex]y = 0.3 * 5 + 1[/tex]

[tex]y = 1.5 + 1[/tex]

[tex]y = 2.5[/tex]

So:

[tex]B = (5,-)[/tex]

[tex]B = (5,2.5)[/tex]

Calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2.5-9}{5 - \frac{80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{15- 80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{-65}{3}}[/tex]

[tex]m = \frac{-6.5*3}{-65}[/tex]

[tex]m = \frac{-19.5}{-65}[/tex]

[tex]m = 0.3[/tex]
