Answer:

(1,3)

Step-by-step explanation:

we know that

If a ordered pair is a solution of the graph

then

the ordered pair belong to the graph  

Plot the points

The ordered pair (1,3) is on the graph    

therefore

is a solution of the equation

see the attached figure

Helppp plsssss!!show your work.<br>Thanks

You are basically just adding, so combine like terms.

3x^2 + 5x^2 = 8x^2

6x - 2x = 4x

4 - 8 = -4

So the answer is D.

If Q is the midpoint of segment PR, PQ = 17 cm, then what is the total length of PR?
Tpy6a [65]

Answer:

34 cm

Step-by-step explanation:

PR = PQ + QR

PQ = QR because Q is the mid-point

Since PQ = 17 cm, then QR = 17 cm

so,

PR = 17 + 17

PR = 34 cm

Examine the linear table to find the slope, y-intercept, and write the equation for this linear relationship ​. NEED HELP PLEASE
gizmo_the_mogwai [7]

Answer:

y = \frac{4}{3} x + 17  

Step-by-step explanation:

The table shows a set of x and y values, thus showing a set of points we can use to find the equation.

1) First, find the slope by using two points and substituting their x and y values into the slope formula, \frac{y_2-y_1}{x_2-x_1}. I chose (-3, 13) and (0,17), but any two points from the table will work. Use them for the formula like so:

\frac{(17)-(13)}{(0)-(-3)} \\= \frac{17-13}{0+3} \\= \frac{4}{3}

Thus, the slope is \frac{4}{3}.

2) Next, identify the y-intercept. The y-intercept is where the line hits the y-axis. All points on the y-axis have a x value of 0. Thus, (0,17) must be the y-intercept of the line.

3) Finally, write an equation in slope-intercept form, or y = mx + b format. Substitute the m and b for real values.

The m represents the slope of the equation, so substitute it for \frac{4}{3}. The b represents the y-value of the y-intercept, so substitute it for 17. This will give the following answer and equation:

y = \frac{4}{3} x + 17
