Susan elevation at the top of a mountain is 1,530 meters meters. After 4 hours of climbing dow her elevation is 680 meters. What is Susans average change in elevation, in meters per hour
?

She is going down the mountain at 212.5 meters per hour.

Step-by-step explanation: 1530-680= 850

850/4= 212.5

170

Step-by-step explanation:

hope this helps

b). 4320 have a nice day

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
