(awarding branliest plus 30 pts)

standing straight up i underhand tossed a dog treat (dog in other room at the time). i tossed it underhand, with my hand about 2 feet high. so my starting point was (0,2).

i have to wall space so i put a tape measure on the ground and noted how high it went in relationship to the book case next to it. i used the height of the bookcase and the tape measure on the ground to estimate that it went up 5 feet high 4 feet away. so the vertex was (4,5).

then i measured on the floor how far away it had landed from where i was when i tossed it in the air. it went 10 feet away and was on the floor so x was zero. the landing point (10,0)

i used desmos online graphing calculator and entered my 3 points as a table. ? then i computed a quadratic regression by entering y1~ ax1^2+bx1+c .

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

true
