Answer:

Step-by-step explanation:

to start this

you need to open the bracket, by multiplying -3(8-f)

we get

-5f = -3*8 -3 * (-f)

-5f = -24 + 3f

we collect like terms by taking f to where there is f so as to simplify our work

so we get

-5f -3f = -24

we get -3f because when a sign + or - crosses an equal sign, the sign changes that is. + changes to -, while - chnages to +

so add them

-8f = -24

minus (-) will cancel minus the we get

8f = 24

divide both side by 8

8f/8 = 24/8

f = 3

so f is = 3

Answer:

Step-by-step explanation:

-5f=-3(8-f)

Opening bracket

-5f = - 24 + 3f

Collecting like terms

-5f - 3f = -24

-8f = -24

Dividing by -8

f = -24/-8

f = 3

Bess and Gina earn $45 per week for delivering flowers. Bess worked for x weeks and earned an additional total bonus of $20. Gin

iogann1982 [59]

Answer:

$45x+20+45y$

Step-by-step explanation:

Let

x -----> the number of weeks worked by Bess

y ----> the number of weeks worked by Gina

we know that

The total money earned by Bess and Gina for delivering flowers, is equal to the sum of the number of weeks worked by Bess and Gina. all multiplied by the weekly rate of $45 plus an additional total bonus of $20

The expression that represent this situation is

$45(x+y)+20$

Distribute

$45x+45y+20$

Rewrite

$45x+20+45y$

How do I turn (-3,-14) and (0,-9) into slope intercept form?

max2010maxim [7]

<h2>Answer:</h2>

y = 5/3x - 9

<h2>Step-by-step explanation:</h2>

For slope intercept form, you should have the slope and the y intercept.

Slope intercept form is...

y = mx + b

y being y
m being slope
x being x
b being the y intercept

Moving on:

To find slope, you have to know the rise and run, or the change in y and the change in x.

To find slope...

(-9 - (-14)) / (0 - (-3))

Now, you should be able to calculate that to find that your slope is...

5/3 or 1 2/3

Now, you should be focused on finding your y intercept where the coordinates are (0, b) where b is your y intercept.

Lucky for you, you already have your y intercept being -9 given in the question.

Finally, to find the slope intercept form! You start off with your main equation for slope intercept form.

y = mx + b

Then you should plug in the numbers you have just found.

Meaning your slope and y intercept...

y = 5/3x - 9

And I believe there is your answer! Tell me if it's wrong please.
