Answer:point c

Step-by-step explanation:

because point c is three lines down from -1. making -1 and 3/8

Answer:

Point C

Step-by-step explanation:

Because -1 3/8 is negative, it is less than 0.

Point A is eliminated.

Because | -1 3/8 | > | 1 |,

Point B is eliminated.

There are 8 tick marks in between (and including) the integers. Each small unbolded tick mark represents 1/8.

Because 3/8 is 3 times 1/8, count 3 down from -1.

You are left with C.

If an athlete runs at a rate of 309 yd. /min. If one lap is 315 yard athlete then athlete covers 18.63 laps in 19 minutes

What is a conversion factor?

A fraction that is equal to "1" is a conversion factor. The numerator and denominator are the same amount, but they are expressed in different units. It is used to change a number's unit of measurement. In order to do that, multiply the initial number by the fraction equal to "1"; this maintains the original number's value but modifies the units.

An athlete run at a rate of 309 yds. /min.

If one lap is 315 yard

Then total number of yards covered by the athlete is 5871.

I.e. 309 x 19 = 5871.

So total laps covered by the athlete in 19 minutes is

     [tex]\frac{5871}{315}=18.63[/tex]

Hence, athlete covers 18.63 laps in 19 minutes

Answer:

1/3

Step-by-step explanation:

Compute the slope of the line through the following points:

p_1 = (-4, 1) and p_2 = (2, 3)

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (-4, 1) and (x_2, y_2) = (2, 3):

= (3 - 1)/(2 - -4)

3 - 1 = 2:

= 2/(2 - -4)

-(-4) = 4:

= 2/(2 + 4)

3.equation, in slope-intercept form, that relates the cost compared to the miles traveled for a Green Caby=x+5

What is an explanation of the slope-intercept form?

Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This form is frequently known as the y = mx + b form.

1. The graph shows that the Green Cab will cost you $5 for a distance of 0 miles.

2. According to the graph, $1 is spent for every mile traveled.

3. Because y increases by the same amount for every 1 increase in x, the slope is 1.

The slope intercept form is y=mx+b.

m=slope

intercept b=y

Since we are aware that the slope is 1, we can enter it.

y=1x+b

=y=x+b

By looking at the graph and calculating what y equals when x is 0, we may get the y intercept.

It is the y intercept (0,5)

So that the equation is in slope intercept form, we may enter that.

Given that

5 positive whole numbers add up to 47

we solve these by using system of equation  

let 5 whole numbers be p, q, r, s and t

equation is: p + q + r + s + t = 47

one of the number is a multiple of 9 the other four numbers are equal  

let p be the multiple of 9

equation is: p + q + q + q = 47

p + 4q = 47

let's try trial and error method q and p are whole numbers, they cannot be decimal  

let p = 9

9 + 4q = 47

4q = 47-9

4q = 38

q = 9.5 it is not whole number, so this is not the number

let p= 18

18 + 4q = 47

4q = 47-18

4q = 29

q = 7.25 it is not whole number, so this is not the number

let p = 27

The inequality in the slope-intercept form is y≥(3x/7)+3 when the graph is in of a linear inequality.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844)[2] and Todhunter's formulations of the equation for a straight line as y = mx + b and y = mx + c, respectively.

Let the linear equation be

y=m x +c

From the graph the lines are passing through the points (-7,0), (0,3)

Slope m =(3-0)/(0+7)

m=3/7

c=y-intercept

Therefore, c=3

Substitute the values in the above equation.

y=(-3/7)x+3

7y=3x+21

But, here we need to use the inequality which satisfies the shaded region.

Let us consider the point (1,2)

7(2)=3(1)+21

14=24 (But 14≠24)

Therefore, 14≥24

So, we have to use ≥ sign

7y≥3x+21

y≥(3x/7)+3

The inequality in the slope-intercept form is,

y≥(3x/7)+3
