Hilary was scuba diving. She was 30 feet below the surface when she swam toward the dive platform. She dropped her camera when she was 10 feet from the surface and had to swim down 15 feet to get it. At what elevation did Hilary retrieve her camera? Negative 10 feet Negative 15 feet Negative 25 feet Negative 30 feet

She picked up her camera at -25ft

Step-by-step explanation:

Given

Required

Determine the position she retrieved her camera

The position where she dropped her camera is given as:

She swim down 15ft;

So, the nee position is

Hence; She picked up her camera at -25ft

Note that: Negative signs represent that she is below the sea level

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
