The line with an x-intercept of (4, 0) and a slope of -2
dlinn [17]

9514 1404 393

Answer:

  y = -2(x -4)

Step-by-step explanation:

The equation of the line is conveniently written in point-slope form, since we are given a point and a slope. That form is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Using the given point and slope, the equation for the line is ...

  y = -2(x -4)

__

This simplifies to the slope-intercept form ...

  y = -2x +8

Could I get an explanation and some help?
True [87]
Think of it as a normal linear equation first. Let's find the slope.
m = rise/run = (3-1)/(0-1) = -2
We know the slope is negative now, so we can immediately get rid of the first two answers. Now, we know that the solutions must be under the line itself, so we can try figuring it out by testing some points. Let's use (0,0).
Is 0 </> 0+3? Since it's <, then we know the last answer is correct (y < -2x + 3).

A cone has a volume of 3533.5 cubic inches and a radius of 15 inches. What is its height?
tia_tia [17]

Answer:

   h=14.9966

Step-by-step explanation:

1. The formula of the volume is:

        V=\frac{ab(h)}{3}

2. So you have to substitute the the data that you have:

       3533.5in^{3}=\frac{ab(h)}{3}

3. To have the area of the base (ab) you have to get the formula of the circle's area and solve:

       A=\pi(r^{2})

       A=\pi(15^{2})

       A=3.1416(225)

       A=706.86in

4. Now you have the area of the base:

        3533.5in^{3}=\frac{706.86(h)}{3}

5. In this step you are going to clear the variable which is the heigh (h) and solve as an equation:

         3533.5in^{3}=\frac{706.86(h)}{3}

     3533.5in^{3}(3)=706.86(h)

               \frac{10,600.5}{706.86}=h

                       h=14.9966

The result may vary depending on the value of \pi that you use,

Ming was planning a trip to Western Samoa. Before going, she did some research and learned that the exchange rate is 6 Tala for
mote1985 [20]

Answer:

18 Tala.

Step-by-step explanation:

1. You have that Ming learned that the exchange rate is 6 Tala for $2. Therefore, if she exchanged $6, she would get:

\frac{6}{2}=\frac{x}{6}

2. Now, you must solve for x, which is sthe amount of Tala:

x=\frac{(6)(6)}{2}\\x=\frac{36}{2}\\x =18

3. Therefore, she would get 18 Tala.
