Point are set up (x,y) you sub the number for x into the equation and see if you get the number for y.
y=4x+3
y=4 (5)+3
y=20+3
y=23
so A isn't the answer
y=4 (17)+3
y=68+3
y=71
B isn't the answer
y=4 (4)+3
y=16+3
y=19
and because 4 is the x value for c and d and there can only be 1 y value for each x you're answer is C because when x=4 y =19 or (4,19)
Answer:
14.2 hectares
Step-by-step explanation:
Fund Mexico, monarch butterflies occupied 1.13 hectares one recent winter, and 4.01 hectares the following winter (one year later)
The formula of Geometric growth
(Pt/ Po)^1/t
Where Pt = Size after t years = 4.01 hectares
Po = Initial size = 1.13
t = times = 1
=( 4.01/1.13 )^1/1
= 3.5486725664
Hence, Geometric growth rate = 3.5486725664.
It's size in hectares after another 1 year = Current size in hectares × Geometric growth rate
= 4.01 ×3.5486725664
= 14.230176991 hectares
≈ 14.2
11.8/2 = 5.9
5.9 squared is <span>34.81
34.81 multiplied by pi is </span>109.358840271
