First, you would do the parentheses which is multiply 4 to -4x to 7 which leave you with the equation 7x-16+28=118. Then you combine the like terms which gives you 7x+12=118. After that you subtract the number 12 to 118 which the next you divide so the answer is 15.14285714285714 and so on which can be simplified to 15.14 or 15.1

Hello from MrBillDoesMath!

Answer:

The protein/calories ratios are equivalent

Discussion:

For the first column

Protein/calories = 24/96 = 1/4

For the second column

Protein/calories = 28/112 = 1/4

So the protein/calories ratios are equivalent

Thank you,

MrB

Line m has the equation y = 1/2x - 4

Mandarinka [93]

Answer:

As the slopes of both lines 'm' and 'n' are the same.

Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.

Step-by-step explanation:

We know that the slope-intercept of line equation is

$y=mx+b$

Where m is the slope and b is the y-intercept

Given the equation of the line m

y = 1/2x - 4

comparing with the slope-intercept form of the line equation

y = mx + b

Therefore,

The slope of line 'm' will be = 1/2

We know that parallel lines have the 'same slopes, thus the slope of the line 'n' must be also the same i.e. 1/2

Checking the equation of the line 'n'

$x-2y=4$

solving for y to writing the equation in the slope-intercept form and determining the slope

$x-2y=4$

Add -x to both sides.

$x - 2y + (-x) = 4+(-x)$

$-2y = 4 - x$

Divide both sides by -2

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

$y=\frac{1}{2}x-2$

comparing ith the slope-intercept form of the line equation

Thus, the slope of the line 'n' will be: 1/2

As the slopes of both lines 'm' and 'n' are the same.

Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.
