A coffee shop is running a promotion where a number of free coffee samples are given away
each day. The equation below can be used to model the number of free coffee samples, y, that
remain to be given away x days after the promotion began. What does it mean that (11,0) is a
solution to this equation?
110x + y = 1,210
A) During the promotion, 11 samples are given away each day.
B) It takes 11 days during the promotion to see 1,210 customers.
C) It takes 11 days during the promotion until none of the samples are remaining.
D) There are 11 samples available at the start of the promotion.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
