Answer: .64 cents, 1 dollar
.64: would sell all 236 cookies
1 dollar: sell 150 cookies
Step-by-step explanation:
150/236 = .64
1 * 150 = 150
Answer:
9
Step-by-step explanation:
9 squared plus 40 squared= 41 squared
Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)
Answer:
The equation for direct variation is y=kx. Direct variation is when 2 variables both change in the same direction. This means that if one variable increases, then the other does as well and vice versa. In this equation, k is the constant of variation. The constant of variation represents the relationship between the 2 variables. Additionally, the k value does not change.
To solve for k, divide both sides by x. This creates the new equation y/x=k. Using this equation, you can take 2 variables, divide them, and find the constant of variation.
For example, take the values x={1,2,3,4} and y={2,4,6,8}. Using the equation y/x=k, we can find the constant of variation. When plugging the first values of each set into the equation you get 2/1. This equals 2, proving that k=2. Even if you use the other values, like 8/4, k still equals 2.
Answer:
3x(x – 3)(x2 + 3x + 9)
Step-by-step explanation:
Because 3x4 – 81x=3x4-3x3
and the formula is
a3-b3=(a-b)(a2+ab+b2)
but since here it is 3x4 we put 3x before the formula.
