Think y=mx+b

Mathematics
1 answer:
ICE Princess25 [194]3 years ago

Answer:

Step-by-step explanation:

3x%2B4y=12 Start with the given equation

4y=12-3x Subtract 3+x from both sides

4y=-3x%2B12 Rearrange the equation

y=%28-3x%2B12%29%2F%284%29 Divide both sides by 4

y=%28-3%2F4%29x%2B%2812%29%2F%284%29 Break up the fraction

y=%28-3%2F4%29x%2B3 Reduce

Looking at y=-%283%2F4%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-3%2F4 and the y-intercept is b=3

Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

 

So we have one point  

Now since the slope is comprised of the "rise" over the "run" this means

slope=rise%2Frun

Also, because the slope is -3%2F4, this means:

rise%2Frun=-3%2F4

which shows us that the rise is -3 and the run is 4. This means that to go from point to point, we can go down 3 and over 4

So starting at , go down 3 units

and to the right 4 units to get to the next point  

Now draw a line through these points to graph y=-%283%2F4%29x%2B3

So this is the graph of y=-%283%2F4%29x%2B3 through the points  and

A cylindrical tank holds 352 cu. ft. of water. The height of the tank is 7 ft. Find the
Rzqust [24]

Answer:

0.3334 ft

Step-by-step explanation:

Measure the height and radius of the tank. The radius is the distance from the center of the tank to its outer edge. Another way to find the radius is to divide the diameter, or width, by two. Square the radius by multiplying the radius times itself and then multiply it by 3.1416, which is the constant pi.

  1. Given height and volume: r = √(V / (π * h)),
  2. Given height and lateral area: r = A_l / (2 * π * h),
  3. Given height and total area: r = (√(h² + 2 * A / π) - h) / 2,
  4. Given height and diagonal: r = √(h² + d²) / 2,
  5. Given height and surface-area-to-volume ratio: r = 2 * h / (h * SA:V - 2),
  6. Given volume and lateral area: r = 2 * V / A_l,
  7. Given base area: r = √(A_b / (2 * π)),
  8. Given lateral area and total area: r = √((A - A_l) / (2 * π)).

What is the slope of the line? -3 -1/3 1/3 3
Paul [167]

Answer:

The slope = Rise over run

Step-by-step explanation:

I would answer your question farther, but you didn't post a picture of the line.

determine two points and count from the left one to the right one. Rise is y so count how many up or down. Run is x so count how many left or right.
