Plug 10 in for y.

10=2x-2.5

Add 2.5 to both sides.

12.5=2x

Divide both sides by 2.

6.25=x

Hope this helps! :)

Your answer would be 6.25.

When finding the answer to this equation, you will insert 10 where 'y'' is in the equation. 10= 2x - 2.5. Then you want to have x alone on one side, so you need to add 2.5 to 10. 12.5= 2x. Once you did this, divide 12.5 by 2 and you have your answer. 12.5/2= 6.25

1/6 of 3 yards=______feet<br><br>I know I just ask one but u get 17 points so plz help I'm stuck
bulgar [2K]

In this question, first we have to see how many feets are in 1 yard .

And there are 3 feets in 1 yard.

So in 3 yards, there are 9 feets

Therefore we will get

\frac{1}{6}*3 yards= \frac{1}{6} * 9 feet = 1.5 feet

Therefore the answer of the given question is 1.5 feet.

A line has a slope of -2 and a Y intercept of -3. Graph the line using the slope and y-intercept. Which of the following points
nikdorinn [45]
<h2>Greetings!</h2>

Answer:

(1.5 , 0) , (-6 , 9) , (3 , -9)

Step-by-step explanation:

First, you need to find the equation of the line, which is:

y = mx + c

Where m is the gradient (or slope) and c is the y-intercept. Simply replace these values with the one given to you:

y = -2x -3

Now, simply draw this line by finding two points,

x = 0

y = -2(0) - 3

y = -3 when x = 0

When x = 3

y = -2(3) - 3

y = -9 when x = 3

Now you can use these points to plot the graph. (attacthed a screenshot of it)

Now simply find which given co-ordinates fit on the line. The points on the line are:

(1.5 , 0) , (-6 , 9) , (3 , -9)
