Determine the value of y in the equation: -5y-9=-(y-1) (show all work)

1 answer:

8 0

1) -5y - 9 = - (y - 1)

2) solve the parenthesis of the right side

-5y - 9 = - y + 1

3) add 5y to both sides

5y - 5y - 9 = -y + 5y + 1

- 9 = 4y + 1

4) Subtract 1 from both sides

-9 - 1 = 4y + 1 - 1

-10 = 4y

5) Divide both sides by 4

-10 / 4 = 4y/4

- 2.5 = y

Answer: y = - 2.5

The revenue of a company that makes backpacks is given by the formula R = 34.S0x, where x represents the number of backpacks sol

alexgriva [62]

Answer:

Revenue = 1380

Step-by-step explanation:

Given:

Revenue means the sales or turnover of a company when it sells its products. In other words, it is nothing but the income of a company on selling the products.

Here, the company is selling backpacks. So, revenue is the amount earned by the company on selling 'x' backpacks. The linear model to represent the same is given below.

The revenue received from selling 'x' backpacks is given as:

$R=34.50x$

Number of backpacks sold (x) = 40

Now, in order to find the revenue received on selling 40 backpacks, we need to plug in 40 for 'x' in the equation above and solve for the revenue, 'R'.

On plugging 40 for 'x', we get:

$R=34.50\times 40\\\\R=1380$

Therefore, the revenue received by the company on selling 40 backpacks is 1380.

3 over 4 open parentheses 1 half x space minus space 12 close parentheses space plus space 4 over 5

lesantik [10]

For this case we have the following expression:

$\frac {3} {4} (\frac {1} {2} x-12) + \frac {4} {5}$

Rewriting the expression we have:

We apply distributive property to the terms of parentheses:

$\frac {3} {8} x- \frac {36} {4} + \frac {4} {5}\\\frac {3} {8} x-9 + \frac {4} {5}\\\frac {3} {8} x- \frac {41} {5}\\$

Answer:

$\frac {3} {8} x- \frac {41} {5}$

An airplane takes off from an airport and travels 1100 miles east and then travels 600 miles north. This trip can be plotted on

IgorLugansk [536]

Answer:

The plane is now at (1100, 600) in unit mile

Step-by-step explanation:

The airport is the point (0 ,0) and the plane travels from there 1100 miles east and thereafter 600 miles north. If the unit is in mile then we may say that the planes co -ordinates are now (1100 , 600)

Since,

positive x -axis points towards east and positive y-axis points towards north.
