Answer:
x = 4; y = 2
Step-by-step explanation:
(1) 3x + 2y = 16
(2) 2x – 2y = 4 Add (1) and (2)
5x = 20 Divide each side by 5
(3) x = 4 Substitute (3) into (2)
2×4 – 2y = 4
8 - 2y = 4 Subtract 16 from each side
-2y = -4 Divide each side by -2
y = 2
<em>Check:
</em>
(1) 3×4 + 2×2 = 16
12 + 4 = 16
16 = 16
(2) 2×4 – 2×2 = 4
8 - 4 = 4
4 = 4
The horizontal line at y=4 doesn't have any slope, so the answer should be relatively easy to find. It's just the slope of Function 2.
y = 8x + 12 is the function for Function 2. 8x is the important part.
So the rate of change differing from both functions is 8.
This information will be modeled using the formula
thus we shall have:
Sn=ar^n
where:
a=first term
r=common ratio
from the information:
a=30 ft
r=60/100=3/5=0.6
therefore the formula will be
Sn=30(0.6)^n
where n is the number of terms:
thus when n=5 th sum will be:
S5=30(0.6)^5
S5=30(0.6)^5
S5=2.33 ft
Answer: 2.33 ft
