The equation relating this should be linear since the increase in amount earned is constant throughout which is $24 per hour. The equation is in the form:
y = mx + b
where,
y = earning
m = slope or earning per hour = $24
x = total number of hours
b = y intercept or initial earning upon visit = $45
Hence,
y = 24x + 45
Since we are working at two separate work sites, therefore each site we must earn 810/2 = 405
So when y = 405:
405 = 24x + 45
x = 15 hours
So you must work 15 hours at each site, 30 in total.
Answer:
(-2,2)
Step-by-step explanation:
Looking at your graph, the part were both lines intersect/meet is at point (-2,2). Since (-2,2) is the point of intersection, it is the solution to the equations.
Hope this helps ^-^
Answer:
A
Step-by-step explanation:
pi*r²=616
22×r²=616×7
r²=4312/22
r=14
now
2piR=2×22/7×14
