Answer:

y=-3x+20

Step-by-step explanation:

3/4x+1/4y=5

-3/4x -3/4x

1/4y=5-3/4x

divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)

Your answer is y=-3x+20

Answer:

134 soda
84 hot dogs

Step-by-step explanation:

Let s represent the number of sodas sold. Then the number of hot dogs sold is (s-50) and the total is ...

s +(s -50) = 218

2s = 268 . . . . . . . . . add 50

s = 134 . . . . . . . divide by 2

134 sodas were sold; 84 hot dogs were sold.

Answer:

Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph $y= \frac {2}{5} x - 3$ is below

$y = - \frac {5}{2} x + 2$

Step-by-step explanation:

Slope of the equation $y= \frac{2}{5} x -3$ is $m_1 = \frac{2}{5}$

Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

$m_2 = - \frac {1}{m_1} = - \frac {5}{2}$

Equation of line in point slope form is given as

$y-y_1=m_2(x-x_1)$

Here (x1, y1) = (4, -8)

$y+8 = - \frac{5}{2} (x-4)$

Simplifying it further

$y = - \frac {5}{2} x + \frac {5}{2} 4 - 8$

$y = - \frac {5}{2} x + 2$

22. A storage container is shaped like a rectangular prism. The volume of the container is1,360 cubic feet. The area of the base

Dovator [93]

The volume of the rectangular prism is

$V=B\times H$

Where:

B is the base area

H is the height

Since the base area is 160 feet^2

Since the volume is 1360 feet^3

Substitute them in the rule above

$\begin{gathered} 1360=160\times H \\ 1360=160H \end{gathered}$

Divide both sides by 160 to find H

$\begin{gathered} \frac{1360}{160}=\frac{160H}{160} \\ 8.5=H \end{gathered}$

The height of the container is 8.5 feet

How are the expressions 8-15 and 8-(-15)?how are they different?

zmey [24]

8 - 15 means subtract the positive number 15 from 8.

8 - 15 = 8 + (-15) = -7

8 - (-15) means subtract the negative number -15 from 8.

Subtracting a negative number is the same as adding a positive number.

8 - (-15) = 8 + 15 = 23

8 - 15 = -7, and 8 - (-15) = 23. The expressions mean different operations and have different answers.
