Answer:

1. (AB) y = 2/3x + -4

Step-by-step explanation:

Formula - y = m(x) + (y-intercept)

m = rise / run

"run = horizontal (left and right)

rise = vertical (up and down)"

the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept

So lets use your first question as an example

1. (AB) y = m(x) + (y-int)

y = m(x) + (-4)

the point goes to the right 6 points and goes up 4 points (rise / run)

y = 4/6(x) + (-4)

You can round up the fraction to 2/3

y = 2/3(x) + -4

mr. smith has a maximum of $50 to spend at a museum. a ticket to the museum costs $7. he can spend p dollars to buy other things

7nadin3 [17]

The inequality that can be used to find the values for p is p + 7 ≤ 50.

Given the information,

Mr. Smith can only spend up to $50 at a museum. The museum admission ticket is $7. He can use his P dollars to purchase other items from the museum.

The total budget is $50.

The cost per ticket is $7

⇒ Total spent ≤ Total Budget

⇒ p + 7 ≤ 50

⇒ p ≤ 43

Therefore, p + 7 ≤ 50 will be the inequality that aids in determining the range of values for p.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 Substitute the value of y in the first equation: Combin

svp [43]

Answer:

X = 1

Step-by-step explanation:

To solve the system of equation by susbtitution:

3x + y = 9

y = –4x + 10

We can follow the steps thus:

<em />

<em>Substitute the value of y in the first equation:</em>

As in the second equation y = -4x + 10 we can substitute in the first equation as follows:

3x + y = 9

3x + -4x + 10 = 9

<em>Combine like terms: </em>

3x + -4x + 10 = 9

Like therms are the therms with X (3x - 4x = -1x):

-1x + 10 = 9

<em>Apply the subtraction property of equality: </em>

-1x + 10 = 9

As 10 is suming, it passes to subtracting the 9:

-1x = 9 - 10

-1x = -1

<em>Apply the division property of equality:</em>

-1x = -1

Dividing in -1:

x = -1 / -1

<h3>X = 1</h3>

How would the number of times edgardo uses a container to fill the 10 gallon cooler change if he uses a one cup container? Expla

olya-2409 [2.1K]

Answer:

Edgardo would use the container <u>160 times</u> to fill.

Step-by-step explanation:

Given:

Edgardo uses a container to fill the 10 gallon cooler.

If he uses a one cup container.

Now, to find the times it would take to fill the 10 gallon container.

As, the capacity of container = 1 cup.

And, the capacity of cooler = 10 gallon.

So, we use conversion factor to find the times the container to fill the cooler:

1 gallon = 16 cups.

10 gallon = $10\times 16\ cups.$

10 gallon = 160 cups.

<u><em>Thus, to fill the 10 gallon cooler 160 cups of container needed.</em></u>

<u><em>And, the container is of 1 cup.</em></u>

So, to get the times he would use the container we divide 160 by 1:

$160\div 1=160.$

<u><em>Hence, 160 times Edgardo would use the 1 cup container to fill the 10 gallon cooler.</em></u>

Therefore, Edgardo would use the container 160 times to fill.
