C represents the number of four-packs of cartridges because the question says there are 4 pack of 42 ounceink cartridges that sell for 85.99...If you were ever to create an equation with this it would be 42c = 85.99
And you can plug in 4, 8, or 16 for c and check how much they would cost over all...your welcome, have a great day
17) replace the given number for "x" and evaluate
a) x² + 2x + 1 ; when x = 3
3² + 2(3) + 1
= 9 + 6 + 1
= 16
b) x² + 2x + 1 ; when x = -4
(-4)² + 2(-4) + 1
= 16 - 8 + 1
= 9
c) x² + 2x + 1 ; when x = 3
(-22.872)² + 2(-22.872) + 1
= 523.128384 - 45.744 + 1
= 478.384384
18) The dependent variable is affected by the other variable and is the "output" The independent variable is the input.
a) y = 3x - 5; "x" is the independent variable
b) the time of day is the independent variable (you would input the time of day to calculate the temperature).
19) Let the x-axis represent the length of the lumber cut off and the y-axis represent the length of the lumber remaining.
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.
sin H = Opposite / Hypotenuse
sin H = 5/13
sin H = 0.384615
<H = 22.6198
<H = 23 (nearest degree)
Answer is first one.
23
The answers A and C contain correct information but both of them provide different advice. so the answer is literally your opinion between a and c
