(20 pts) How would I graph a slope that passes through a certain point? Is there a certain equation that could help me? Say for

example I want to graph y=x/4 but have it pass through (-1, -1/3)

Answer:

Use point-slope form.

Step-by-step explanation:

Let us say (x1, y1) are the coordinates you want to pass through and m is the slope, you would right it like this:

y-y1=m(x-x1)

In this case, the slope is 1/4 and it passes through (-1, -1/3)

y+1/3=1/4(x+1)

If you want to simplify this, you get

y=x-1/12

The area of a circular swimming pool is approximately 18 m2 which is the best estimate of the radius
Hitman42 [59]

Answer:

2.39 meter

Step-by-step explanation:

Let r be the radius of the circular swimming pool and A be the area of circular swimming pool.

Given.

The area of circular swimming pool is 18m^{2}

A = 18

The area of circle = \pi r^{2}

A=\pi r^{2}-------(1)

Put A value in equation 1.

18=\pi r^{2}

r^{2}=\frac{18}{\pi }

Put \pi =\frac{22}{7} value.

r=\sqrt{ \frac{18}{\frac{22}{7} }

r=\sqrt{\frac{18\times 7}{22} }

r=\sqrt{ \frac{126}{22} }

r=\sqrt{5.72}

r=2.39mtere

The radius of the circle is 2.39 meter.

Can someone help me w #10 and #11
Aleksandr-060686 [28]

Answer:

  10. Expanded vertically by 3, shifted left 2 and up 4.

  11. Shifted right 6 and up 7.

Step-by-step explanation:

This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.

Here are the transformations used in this problem:

  • f(x -a)  . . . .  shift f(x) to the right by "a" units
  • f(x) +a  . . . .  shift f(x) up by "a" units
  • a·f(x)  . . . . .  vertically scale f(x) by a factor of "a"

For these problems, the parent function is f(x) = 1/x.

__

10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.

The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.

The addition of 4 to the function value means the function has been shifted up by 4 units.

__

11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.

Please help i will give brainliest.
WITCHER [35]

Coming to the Meaning of Mid point of a line segment = It is a point which divides a segment i.e a definite length into two equal parts or two congruent parts.

So, The Statement is

A midpoint of a segment is a point that divides a segment into two congruent segments.

Yes i think it is Reversible.

And the Reverse statement is if a segment is divided into two equal parts then that point is the mid point of that segment.

All the given option  are

A. If a point does not divide a segment into two congruent segments, it is not a midpoint.

.  

B. point that divides a segment into two congruent segments is a midpoint.

C. This statement is not reversible.

D. A point is a midpoint of a segment if and only if it divides the segment into two congruent segments.
