D. The bank balance in John's saving account increases from Month 4-5

Step-by-step explanation:

Lets go with one answer at a time

It talks about the fact that there is not change from Month 1 to Month 2

However, an entire $750 has changed therefore, option A would be incorrect.

This one also talks about the fact that there is no change from Month 2 to Month 3

When in fact it has changed more than $250 downwards, so option B would be incorrect.

This one talks about the bank account decreasing from Month 3 to 4

However, in that time period it stays the same therefore, option C would also be incorrect.

Now that should mean that D is the right answer, but, we should still check.

This talks about John's bank account increasing from Month 4-5

Yes it does change upwards. It increases $750 again.

Therefore, your answer would be D. The bank balance in John's saving account increases from Month 4 to 5.

$y> \frac{1}{3}x$ and y≤ -x +4 .

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 = $\frac{1-0}{3-0} = \frac{1}{3}$ .

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

plugging slope m= $\frac{1}{3}$ and b=0 in slope-intercept form y=mx+b, we get

$y=\frac{1}{3}x$ .

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

$y> \frac{1}{3}x$ .

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

slope of the solid line would be = $\frac{4-1}{0-3} = \frac{3}{-3}=-1$ .

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

y≤ -x +4 .
Write a system of inequalities to represent the shaded portion of the graph.
