Answer from: Kaylenejohnson00

10 pounds

Step-by-step explanation:

13-3=10 ibs

Answer from: laladance123

74 pounds

Explanation:

For now, let's ignore the 73 pounds.

The 13 ounces she gains is added onto the initial 3 ounces to get 3+13 = 16 ounces = 1 pound.

So we add this 1 pound onto the 73 pounds from earlier to get the answer to be 73+1 = 74 pounds

We could write the steps out like this

(73 pounds, 3 ounces) + (13 ounces)

(73 pounds + 3 ounces) + (0 pounds + 13 ounces)

(73 pounds + 0 pounds) + (3 ounces + 13 ounces)

73 pounds + 16 ounces

73 pounds + 1 pound

74 pounds

Answer from: Quest

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