The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y. Which is the graph of the equation y = 8.1x? A coordinate grid with a curved line starting at (1, 8) curving down and to the right passing through (2, 4), (4, 2), and (7, 1)

A coordinate grid with a straight line starting at (0, 0) and (1, 8).

A coordinate grid with a straight line starting at (0, 2) passing through (2, 4) and (6, 8).

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
