We are given the equation of a line

y = -2x + 1

We have to find the value of y at three different values of x i.e. x = 0, -3 and 1

In order to find the value of y at any given x, simply replace x by that number.

So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)

Similarly for x=-3, we get
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)

And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y = -1
This can be expressed as an ordered pair as (-1, -1)

Answer:

When x = 1 , we get, y = -1      

Step-by-step explanation:

Given:   Linear equation y = - 2x + 1

We have to complete the table so that each line of table for the values of x and y form the ordered pair of x and y.

Consider the given linear equation y = -2x + 1

Since, by putting different values of x , we can get values of y .

Here, when we put x = 1

We get,

y = -2 (1) + 1

Simplify, we get,

y = -2 + 1 = -1

thus, when x = 1 , we get, y = -1

I need help on this problem
Arte-miy333 [17]

Answer: QR=4.04

Step-by-step explanation:

For this exercise you must use the followinG Trigonometric Identity:

tan\alpha=\frac{opposite}{adjacent}

In this case, given the right triangle PQR, you can identify that:

\alpha=60\°\\opposite=PR=7.0\\adjacent=QR

Then, the  next step is to substitute those values into tan\alpha=\frac{opposite}{adjacent}:

tan(60\°)=\frac{7.0}{QR}

And the final step is to solve for "QR" in order to find its value.

So you get that this is:

(QR)(tan(60\°))=7.0\\\\QR=\frac{7.0}{tan(60\°)}\\\\QR=4.04

The points (-6, r)<br> and<br> (6,3) lie on a line with slope 3/4. Find the missing coordinate r.
iren [92.7K]

Answer:

r=-6

Step-by-step explanation:

m=\frac{y2-y1}{x2-x1} \\\frac{3-r}{6-(-6)} =\frac{3}{4} \\4(3-r)=3(12)\\12-4r=36\\-4r=24\\r=-6

How many unique triangles can be drawn with side lengths 8 in., 12 in., and 24 in.? Explain.
Elanso [62]

Answer:

2

Step-by-step explanation:

To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!
