Plz william’s typical running speed is 6 km/h. the difference between his fastest speed and his typical speed is 1.5 km/h. the equation f-1.5=6 can be used to represent this problem, where f is william’s fastest speed. what is william’s fastest speed?

William's fastest speed is 7.5 km/h

Step-by-step explanation:

Let the fastest speed of William is f therefore from the question's statement the equation will be

f - 6 = 1.5

Here difference between William's fastest speed and typical speed is 1.5 km/h

Now we will add 6 on both sides of the equation

(f - 6) + 6 = 1.5 + 6

f = 7.5 km/h

So the fastest speed is 7.5 km/h

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
