Joe borrowed $7000 from the bank at a rate of 7% simple interest per year how much interest did he pay in six years

840

Step-by-step explanation:

2,000(0.07) = 140

find the amount of interest per year

140(6) = 840

hope it helps!

Joe paid $2,940 in interest after six years.

Step-by-step explanation:

Since Joe borrowed $7000 from the bank at a rate of 7% interest per year. We need to find 7% of 7,000.

7,000 x 0.07 = 490

Since we need to find out how much interest Joe paid after six years, we need to multiply 490 by 6.

490 x 6 = 2,940

Therefore, Joe paid $2,940 in interest after six years.

Hope this helps! :D

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
