How do you solve thisy=-x-1y=2x-6​

Lerok [7]3 years ago

Answer:

x = 5/3

y = -8/3

Step-by-step explanation:

To solve y = 2x - 6​ substitute the y for -x - 1 and solve for x.

-x - 1 = 2x - 6 Now you can solve this like a regular inequality. Start by subtracting 2x on both sides.

-3x - 1 = -6 Now add 1 to both sides

-3x = -5 Divide by -3 on both sides

x = 5/3 (the negatives cancel and become positive)

Because you have x, you can go back and properly solve for y. Substitute x for 5/3

y = 2(5/3) - 6 Simplify the right side to get your answer.

y = 10/3 - 6 In order to subtract 6, you first have to convert it to a fraction with a denominator of 3. To do this, put 6 over 1 (6/1) then find the least common denominator of 3 and 1, which is 3. Now multiply 1 by 3 and 6 by 3 to get 18/3

y = 10/3 - 18/3

y = -8/3

I hope this helped :)

Answer: The answers are in the photo.

Step-by-step explanation:

To solve question 4, you have to work backwards. Plug 40.82 as C in the formula C = D x 3.14. It would now look like: 40.82 = D x 3.14. Divide 40.82 by 3.14 and you would receive 13 as the diameter. However, we are searching for the radius. The radius is half of the diameter. 13 / 2 is 6.5

To solve question 5, you'll need to use the formula C = D x 3.14. So far, we know D is 6. 6 x 3.14 is 18.84. Yet, we need to find the cost. Each foot costs $12.50, so that's what we multiply to 18.84. In the end, the cost is $235.50.

Help! graph Y - 2 = -3/4 (X-6). please use the graph I provided
Fiesta28 [93]

A graph of this equation y - 2 = -3/4(x - 6) is shown in the image attached below.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that is typically used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate.

Next, we would rearrange and simplify the given given equation in slope-intercept form in order to enable us plot it on a graph:

y - 2 = -3/4(x - 6)

Opening the bracket, we have:

y - 2 = -3x/4 + 18/4

y = -3x/4 + 18/4 + 2

y = -3x/4 - 26/4

y = -3x/4 - 13/2

Therefore, the slope is equal to -3/4 and the y-intercept is equal to -13/2.

In conclusion, we can logically deduce that the graph representing the given linear equation does not show a proportional relationship between the value of x and y.

72 orders in 3 days equas how many orders per day?
sergey [27]

72 orders in 3 days

that means

In 3 days, the number of orders = 72

Now to find the number of orders per day, i.e number of orders in 1 day

for this divide the total number of orders with the number of days

\begin{gathered} \text{Number of orders per day =}\frac{Number\text{ of orders in thr}ee\text{ days}}{Total\text{ number of days}} \\ \text{Number of orders per day }=\frac{72}{3} \\ \text{Number of orders per day }=24 \end{gathered}

Thus, there are 24 orders per day

Answer : 24 orders per day
