Answer:

-9

First, we must convert the equation into slope intercept form, by solving for y.

Step 1: Add 7x to both sides.

-7x-5y+7x=-45+7x-5y=-45+7x\\

Step 2: Regroup terms.

-5y=7x-45

Step 3: Divide both sides by -5.

y=-\frac{7x-45}{5}

y=-\frac{7}{5}x-9

Now we can determine the y-intercept by just looking at the equation! the y-intercept is the only constant, -9

​

I hope this helps!

A brainliest will be greatly appreciated!

Answer:

The y-intercept is at the point (0, 9).

Step-by-step explanation:

WE have the y intercept when x = 0:

-7(0) - 5y = -45

-5y = -45

y = -45/-5 = 9.

When ordering the Kids' Lunch at Burger Universe, the customer must choose a size, whether or not to have cheese, a type of bun,
AlekseyPX

Answer:

192 Kids' Lunches are possible.

Step-by-step explanation:

The client must make 5 decisions:

1) Size (junior, small, medium, large)

2) Cheese (with or without)

3) Type of bun (white, wheat)

4) Side order (fries, onion rings, fruit cup)

5) Drink (orange, grape, cherry, lemonade)

Since the client must make all 5 decisions all the time, we will multiply the number of options we have:

1) For size, he has 4 options,

2) For cheese, he has 2 options,

3) For type of bun, 2 options,

4) For side order, 3 options,

5) For drink, 4 options.

Therefore, the number of total options he has is 4 x 2 x 2 x 3 x 4 = 192 Kids' Lunches.

-12x - 12y = 4 3x + 3y = 0
Svetradugi [14.3K]

Answer:

no Solution

Step-by-step explanation:

-12x-12y=4\\ 3x+3y=0

12x-12y=4

add 12y to both sides

12x-12y+12y=4+12y

divid both sides by -12

\frac{-12x}{-12}=\frac{4}{-12}+\frac{12y}{-12}

simplfy

x=-\frac{1+3y}{3}

\mathrm{Substitute\:}x=-\frac{1+3y}{3}

\begin{bmatrix}3\left(-\frac{1+3y}{3}\right)+3y=0\end{bmatrix}

\begin{bmatrix}-1=0\end{bmatrix}
