You want to distribute and then combine the like terms, as per order of operations. Start by multiplying the 2 by -n and -3, so you get -2n-6. Then distribute the -7 to the 5 and 2n, so you get -35-14n. Combine your n’s and constants, and get -16n-41

A phone company is offering several different prepaid data plans.

yulyashka [42]

The data plan that has the cheapest deal is given by the ratio of the data

plan price to the GB allocated.

The deal that has the cheapest price per GB is B. Prepaid Single Phone Plan $45 for 16 GB.

The given phone data plans are;

$\begin{tabular}{|l|cl|}&Prepaid Single Phone Plan&Prepaid Family Plan\\ a&\$30 for 1 GB &\$30 for 1 GB\\b& \$35 for 6 GB & \$40 for 6 GB\\ c&\$45 for 16 GB&\$50 for 16 GB\\d & \$65 for Unlimited Data & \$70 for Unlimited Data\end{array}\right]$

The price per GB are;

Plan a = $30 ÷ 1 = $30 per GB

Plan b = $35 ÷ 6 = $5.8 $\overline 3$ per GB and $40÷ 6 = $6. $\overline 6$ per GB for Family Plan

Plan c = 45 ÷ 16 = $2.8125 per GB and $3.125 per GB

Plan d = $65 for Unlimited Data = 65 ÷ ∞ ≈ 0; $70 for Unlimited Data = 0

Therefore, the plan with the cheapest price per GB from the given option is option B. Prepaid Single Phone Plan $45 for 16 GB.

3x + 6y = 4y - 4

gulaghasi [49]

Answer: y = 2/3x + 41/3

Step-by-step explanation:

First convert the equation into slope-intercept

3x + 6y = 4y - 4

-4y -4y

3x + 2y = -4

-3x -3x

2y = -3x - 4

y = -3/2x - 2

Perpendicular lines have a negative reciprocal for their slopes.

The negative reciprocal of -3/2 is 2/3

Now using the slope 2/3 you will use the formula y =mx +b and input the slope, and the x and y coordinates of the given point, (-10,7), to solve for the y-intercept.

7 = 2/3(-10) + b

7 = -20/ 3 + b

+ 20/3 + 20/3

b = 20/3 + 21/3 = 41/3

Since the the y-intercept is 41/3 then the equation will be , y = 2/3x + 41/3
