Answer question 3 and also I will give you brainiest if you give the correct answer hurry!!!

icang [17]

To find the rate of change, you look at how much the y value increases with a change of 1 x. We see that as x increases from 1 to 2, y increases from 120 to 144. Then we subtract 144-120 to find the rate of change, which is just 24 (also note that x changes by 1 here).

Then for the initial value:
We see that y increases by 24 for 1 x, so subtracting the value at x=1 by 24 we get 120-24 = 96, which is the initial value.

Hope this helps

please solve the question and show your work what property is illustrated by 5(8-6) = 5x8-5x6 is it a. distributive property or

juin [17]

That is a display of the distributive property.

This is shown because when a number is written directly next to a set of parentheses, you must multiply each value inside the parentheses by the number on the outside.

In this case, 5(8-6) means that you must multiply 5 by 8, as well as by -6.

The right side of the equal sign in the given problem shows both of those steps separately, which is why it is a display of the distributive property. The correct answer is A.

Please solve the question below 1

Fiesta28 [93]

Answer:

Step-by-step explanation:

Find the mean:

Day 1: 2

Day 2: 1

Day 3: 4

Day 4: 5

Day 5: 0

Day 6: 7

Mean = $\frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17$

This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.

Therefore we can conclude that:

"Chawrdi complied with the guideline because the mean number of hours played is $\frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17$ .

Okay this my last one can y'all help

a. The solution is (0,2)

b. The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.

Step-by-step explanation:

Given equations are:

$y = 5x+2\ \ \ \ Eqn1\\12.5x+2.5y = 5\ \ \ \ Eqn2$

a. Solution

Putting y = 5x+2 in equation 2

$12.5x+2.5(5x+2) = 5\\12.5x+12.5x+5 = 5\\25x +5 = 5\\25x = 5-5\\25x = 0\\x = 0$

Putting x = 0 in equation 1

$y = 5(0)+2\\= 0+2 = 2$

Hence,

The solution is (0,2)

b: Reason:

The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.
