Answer:

y = -2/3x + 5 1/3

Step-by-step explanation:

Find the slope:

4 - 6 / 2 - (-1) = -2/3

Put it in point-slope form:

y - 6 = -2/3(x + 1)

rearrange:

y - 6 = -2/3x - 2/3

y = -2/3x + 5 1/3

Answers

Answer:

D: 12

Step-by-step explanation:

1) So what I did at first was convert the fractions into decimals.

(Personally, this makes it easier, for me at least)

[tex]\frac{1}{4} = 0.25\\[/tex][tex]\frac{3}{5} = 0.60[/tex]

2) The problem states that for every 0.25 cups of broccoli, 0.60 grams of fiber are added as well to the mix. You can also convert this into a fraction. (It doesn't matter which one is the numerator/denominator, but for this example, I used the 0.25 cups of broccoli as the numerator.

[tex]\frac{broccoli}{fiber} =\frac{0.25}{0.60}[/tex]

3) Next step would be making another fraction. This time, the fraction is for the 5 cups of broccoli. Since we don't know the amount of grams for the fiber, we will replace it with an "x".

[tex]\frac{broccoli}{fiber} =\frac{5}{x}[/tex]

4) Realize, that | [tex]\frac{0.25}{0.60} =\frac{5}{x}[/tex] | To figure out the answer to this part, you can cross-multiply

[tex]0.25x = 5(0.60)[/tex][tex]0.25x = 3[/tex]

5) Then at last, divide both sides by [tex]0.25[/tex] and you'll get:

[tex]x=12[/tex]

Answers

Answer:

x = -5, and y = -6

Step-by-step explanation:

Suppose that we have two equations:

A = B

and

C = D

combining the equations means that we will do:

First we multiply both whole equations by constants:

k*(A = B) ---> k*A = k*B

j*(C = D) ----> j*C = j*D

And then we "add" them:

k*A + j*C = k*B + j*D

Now we have the equations:

-x - y = 11

4*x - 5*y = 10

We want to add them in a given form that one of the variables cancels, so we can solve it for the other variable.

Then we can take the first equation:

-x - y = 11

and multiply both sides by 4.

4*(-x - y = 11)

Then we get:

4*(-x - y) = 4*11

-4*x - 4*y = 44

Now we have the two equations:

-4*x - 4*y = 44

4*x - 5*y = 10

(here we can think that we multiplied the second equation by 1, then we have k = 4, and j = 1)

If we add them, we get:

(-4*x - 4*y) + (4*x - 5*y) = 10 + 44

-4*x - 4*y + 4*x - 5*y = 54

-9*y = 54

So we combined the equations and now ended with an equation that is really easy to solve for y.

y = 54/-9 = -6

Now that we know the value of y, we can simply replace it in one of the two equations to get the value of x.

-x - y = 11

-x - (-6) = 11

-x + 6 = 11

-x = 11 -6 = 5

-x = 5

x = -5

Then:

x = -5, and y = -6

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.
