How to chose a reasonable scale and interval to graph each set of data with these numbers - 70, 35, 55, 10, 43, 25, 80 and three numbers, 4,700; 2,000; 3,400; 1,650; 2,800

For 70, 35, 55, 10, 43, 25, 80

Scale

I small square= 1 unit

For 4,700; 2,000; 3,400; 1,650; 2,800

I small square=100 unit

Step-by-step explanation:

We choose a scale such that all the points can be plotted on the graph.

For 70, 35, 55, 10, 43, 25, 80

the range of data is from 10 to 80

so if we choose I small square= 1 unit, we will be able to plot all the points on the graph.

For 4,700; 2,000; 3,400; 1,650; 2,800

the range of data is from 1600 to 4700

If we choose I small square=100 unit, we will be able to plot all the points on the graph with 1650 plotted in the middle of a small square.

first one is a: renaming a fraction. second one is c: de-c

my explanation is that these were the answers on edg : )

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
