WILL GIVE 32 POINTS FOR WHOEVER GIVES CORRECT ANSWER

Brilliant_brown [7]

Graph the line that goes through the point (3,-1) and has a y-intercept of -4:

You can simply graph two points to create the line for this problem. The points are (3, -1) and (0, -4). The slope for this line is 1/1 too, which means that if you need more points, you would start at either of the two given points and go up one unit and over one unit to the right.

Select three points that the line would go through (y = x - 3):

In the equation, the y-intercept is given, which is one point - (0,-3). Then, we can go up one unit and right one unit to find a second point - (1,-2). And also down one unit and left one unit to find a third point - (-1,4).

Which equation represents the same relationship shown in the graph:

First, let's find the y-intercept, which is (0,6). Then, we can find other points where the line crosses and count how many units up and to the right that would be, which is 1/1. Therefore, the correct equation is B - y = x + 6.

Which of the following graphs represents y = x - 2:

The y-intercept is (0,-2) and the slope is positive and 1/1. We are looking for a graph that crosses through the point (0,-2), points up and to the right, and increases by 1 unit up and 1 unit right each time. Therefore, the correct graph is B.

Hope this helps!! :)

Determine the value of g(4), g(3 / 2), g (2c) and g(c+3) then simplify as much as possible.

jeka94

Answer:

$g(4) = 8 \pi h\\\\g(\frac{3}{2}) = 3 \pi h\\\\ g(2c) = 4 \pi ch\\\\g(c+3) = 2 \pi hc+6\pi h$

Step-by-step explanation:

You need to substitute $r=4$ into $g(r) = 2 \pi r h$ . Then:

$g(4) = 2 \pi(4)h\\\\g(4) = 8 \pi h$

Substitute $r=\frac{3}{2}$ into $g(r) = 2 \pi r h$ . Then:

$g(\frac{3}{2}) = 2 \pi(\frac{3}{2})h\\\\g(\frac{3}{2}) = 3 \pi h$

Substitute $r=2c$ into $g(r) = 2 \pi r h$ . Then:

$g(2c) = 2 \pi(2c))h\\\\g(2c) = 4 \pi ch$

Substitute $r=c+3$ into $g(r) = 2 \pi r h$ . Then:

$g(c+3) = 2 \pi (c+3)h\\\\g(c+3) = 2 \pi hc+6\pi h$

write an equation in slope intercept form of the line perpendicular to the graph of 5x-2y=7 that passes through (3,-2)

alexira [117]

Given :-

A equation which is 5x - 2y = 7 .

To Find :-

The equation of the line perpendicular to the given line and passes through (3,-2) .

Solution :-

Given equation to us is ,

$\longrightarrow 5x -2y = 7$

Convert it into slope intercept form which is y = mx + c ,

$\longrightarrow 2y = 5x - 7$

Divide both sides by 2 ,

$\longrightarrow y =\dfrac{5}{2}x -\dfrac{7}{2}$

Now on comparing to slope intercept form , we have ,

$\longrightarrow m =\dfrac{5}{2}$

And as we know that the product of slopes of two perpendicular lines is -1 . Therefore the slope of the perpendicular line will be negative reciprocal of slope of the given line . As ,

$\longrightarrow m_{\perp}= \dfrac{-2}{5}$
