Answer: 11x-10y

Step-by-step explanation:

Combine like terms.

(5x+3y)-(2x-7y)+8x

3x + 8x

Remember to distribute the negative.

-(-7y) = +7y

3y +7y

Combine like terms once again.

3x+8x= 11x and 3y+7y= 10y

I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)

Answer:1

Step-by-step explanation:

The line is intercepted with the number one

[tex](42 \times 51) + 14 = [/tex]

Answer:

All of them demonstrate the distributive property, except for number 4. 1-3 all have a number on the outside of the parenthesis to distribute itself to the number and variable within the parenthesis, while #4 has a plus sign outside each pair of parenthesis, making you unable to distribute those numbers.

Answer:

"rise over run" or "rate of change"

Step-by-step explanation:

"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.

A gradient is really just another name for slope, not a description OF a slope.

Answer:

steeper

Step-by-step explanation:

D) Vertically compressed

E) Flatter

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

Explanation:

An example would be if a = 0.5 which leads to the graph being half as tall as it used to be since 1/2 = 0.5; notice how a = 0.5 makes 0 < a < 1 true. Since the graph is squished vertically, the graph is flatter.

We don't have a reflection over the x axis since 'a' is not negative.

Answer:

The answer is 12.72 hope this helps

Step-by-step explanation:

You'll add them it's just like simple addition but you just have to know where the decimal point will be after adding

3.78

+8.94

12.72

When you are adding you start from the back with back I mean the end so when you add 8 plus 4 it's going to be 12 then you write or type the 2 and then carry the 1 and add it to the 7 which is going to be 8 then you add the 8 to the 9 which is going to be 17 that's why we have the 7 there then you carry 1 and add it to the 3 which is going to be 4 and then 4+8 is going to be;12

That's how we got the 12.72

Hope you understand

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

[tex]Discount=\dfrac{35}{100}x[/tex]

Amount saved in sale = $25

[tex]0.35x=25[/tex]

Divide both sides by 0.35.

[tex]x=\dfrac{25}{0.35}[/tex]

[tex]x=71.42857[/tex]

[tex]x\approx 71.43[/tex]

Therefore, the regular price of the tennis shoes is $71.43.

The correct statement is the difference of the means is 0.5.

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary. A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

Given:

As, from the box plot mean of boys is

= (1 x3 + 2x 7 + 3 x 6+ 4 x 2 + 5 + 6) /20

= 2.7

and, mean absolute deviation of boys

= (1.7 x 3 + 0.7 x 7 + 0.3 x 6 + 1.3 x 2 + 2.3 + 3.3)/ 20

= 1

now, from the box plot mean of girls is

= (1 x 2 + 2 x 4 + 3 x 7+ 4 x 4 + 1 x 5 + 6 x 2) /20

= 3.2

and, mean absolute deviation of girls

= (2.2 x 2+ 1.2 x 4 + 0.2 x 7+ 0.8 x 4 + 1.8 x 1+ 2.8x 2)/ 20

= 1.06
