Answer: 
Step-by-step explanation:

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.


Therefore, the slope is
.
Where are the graphs? a function is when every input is paired with exactly one output(every x value must have exactly 1 y value). the vertical line test helps determine a function, a vertical line can’t intersect a graph at more then one point, if it does intersect in more then 1 point then it’s not a function
64,500 would be the answer
Answer:
∠ABC= 180° -21° -37° (∠ sum of triangle ABC)
∠ABC= 122°
Using sine rule,

AB= 200(sin21°)/sin 122°
AB= 84.5 units (3 s.f.)

BC= 200(sin37°)/ sin122°
BC= 142 units (3 s.f.)
