Answer:
5200
Step-by-step explanation:
2000 x 20% = 400
400 x 8 = 3200
2000 + 3200 =5200
Divide by the coefficient of y.
y = (45/9)x
y = 5x
The constant of proportionality is 5.
<h3>
Answer: Choice D</h3>
==========================================================
Explanation:
If you plug in x = -2, then,
y = 4x-2
y = 4(-2)-2
y = -8-2
y = -10
This shows that the answer must be choice D, as this is the only answer that has x = -2 lead to y = -10. Note the first column of table D.
We could stop here if you wanted.
----------------------
If we kept going and plugged in x = 0, then,
y = 4x-2
y = 4(0)-2
y = 0-2
y = -2
We have x = 0 lead to y = -2. This matches with the second column of table D.
-----------------------
Lastly, if we plugged in x = 2, then we get,
y = 4x-2
y = 4(2)-2
y = 8-2
y = 6
So the third column of table D is also confirmed.
Surface Area:
S= 2(lw + lh + wh)
S= 2( 10(4) + 10(3.5) + 4(3.5) )
S= 2( 40 + 35 + 14 )
S= 2( 89 )
S= 178
Your surface area is 178 feet
Answer:
C=1 ft
Step-by-step explanation:
c2= a2 + b2 - 2ab
= 8^(2) + 7^(2) - 2(8)(7)
= 113 -112
c2= 1 put a square root on c2 and 1
c = 1
