Draw a graph for the situation. you walk 1 mile to the bus stop, ride the express bus for 2 miles, and then walk another mile to your home.

I would say the answer is D. it doesn't let me answer the explanation for d but it is d .

Step-by-step explanation:

A.a.graphThe horizontal axis extends from 0 to 60 and is labeled 'Time (min).' The vertical axis extends from 0 to 5 and is labeled 'Distance (mi).' The graph begins at the point 30 comma 0 and moves up and to the right, ending at point 38 comma 3. The next section of the graph continues from the point 38 comma 3 and moves up and to the right, ending at point 54 comma 4.  

B.b.graphThe horizontal axis extends from 0 to 60 and is labeled 'Time (min).' The vertical axis extends from 0 to 5 and is labeled 'Distance (mi).' The graph begins on the left at the point 0 comma 0 and moves up and to the right, ending at point 30 comma 2. The next section of the graph continues from the point 30 comma 2 and moves up and to the right, ending at point 36 comma 4. The next section of the graph continues from the point 36 comma 4 and moves horizontally and to the right to the point 55 comma 4.

C.c.graphThe horizontal axis extends from 0 to 60 and is labeled 'Time (min).' The vertical axis extends from 0 to 5 and is labeled 'Distance (mi).' The graph begins on the left at the point 0 comma 0 and moves up and to the right, ending at point 14 comma 1. The next section of the graph continues from the point 14 comma 1 and moves horizontally and to the right to the point 45 comma 1. The next section of the graph continues from the point 45 comma 1 and moves up and to the right, ending at point 54 comma 4.  

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
