Answer:
y = 2x^2 + 16x + 11
Step-by-step explanation:
2(x + 4)^2 - 21
2(x + 4)(x + 4) - 21
2(x^2 + 8x + 16) - 21
2x^2 + 16x + 32 - 21
2x^2 + 16x + 11
Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) = 
6.31 = 
w = 
w = 9.82
Similarly,
tan(39°) = 
0.81 = 
0.81 = 
9.82 + x = 
x = 76.56 - 9.82
x = 66.74
Answer: the graph increases from left to right, since the price goes up. If you were to actually graph this, the years would be on the bottom and the price would be on the left side, so since the price is going up, so is the graph. :)
Answer:
(Option 2) y= x+ 4
Step-by-step explanation:
Please see attached picture for full solution.
To find equation of a line, you need to find the gradient, which is represented by m, and then substitute a coordinate.
1 gallon______8.354 lbs.
11.81 gallons______?
8.354 x 11.81 = 98.66
98.66 / 1 = 98.66 lbs
