Answer:

-2x+8

Step-by-step explanation:

Hey there!

we can write the equation (-x+3)-(x-5) as 1(-x+3)-1(x-5)

= 1(-x+3)-1(x-5)

then we use the distributive property

=1(-x+3)-1(x-5)

= -1x+3-1x+5

then we get the x numbers to one side and the numbers without x to one side.

= -1x-1x+5+3

then we add them( for adding -1x-1x we use the rules for adding numbers negative number then there are two negative like -1x-1x we add them when you add them when the answer comes the answer will be negative )

= -2x-+8 is the farthest we can simplify.

$( - x + 3) - (x - 5)$

$= - x + 3 - x + 5$

$= - 2x + 8$

$= - 2(x - 4)$

Hence, Answer is = - 2(x - 4)

Help with 6 a and b please

34kurt

Answer:

a) $y=\frac{50}{x}$

b) $y=25$ when $x=2$

Step-by-step explanation:

$y=\frac{k}{x}$ since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

$10=\frac{k}{5}$

Multiply both sides by 5:

$10(5)=k$

$50=k$ .

So the equation is:

$y=\frac{50}{x}$

What is y when x=2?

$y=\frac{50}{2}$

$y=25$

What is the median of this data set?

bazaltina [42]

Answer:

Step-by-step explanation:

Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.

and for extra just in case.

Mean=16.222

the mean= the average of the data set

Mode is 13,14

The mode is the number that appears the most in a data set and 13 and 14 appear twice.

Your range is=13

Range is the highest number subtracting the lowest number so 24 -11 which =13

Minimum is 11 because the minimum is the lowest number in data set..

Maximum is 24

Maximum is the highest number in the data set.

I hope this helps have a awesome day:)

Jerry charges $15 for each lawn that he cuts. Depending homework and chores, he has time to cut at most 10 lawns a week. Jerry h

vova2212 [387]

Answer: D) Number of yards Jerry cuts; 0 ≤ x ≤ 10

Step-by-step explanation:

Here the given function that describes the total profit,

y = 15 x - 10

Where x represents the number of lawns Jerry cut in a week.

But, Depending homework and chores, he has time to cut at most 10 lawns a week.

Thus, x ≤ 10

Also, the number of lawns can not be negative.

Therefore, x ≥ 0

And, the value of x will decide the domain of the function y,

Thus, the domain of the given function is,

0 ≤ x ≤ 10

⇒ Option D is correct.
