Answer:
Step-by-step explanation:
- V(x) = x³ - 8x² + 19x - 12
<u>The two of the dimensions given</u>
<u>and the third one is</u>
<u>Multiply the three dimensions to get the volume:</u>
- (x - 1)(x - 3)(x + a) =
- (x² - 4x + 3)(x + a) =
- x³ - 4x² + 3x + ax² - 4ax + 3a =
- x³ - (4 - a)x² + (3 - 4a)x + 3a
Comparing with the given function, we get a = - 4
<u>So the missing dimension is:</u>
Step-by-step explanation:
so,
y = -9x + 2
now we need to transform this equation that actually x is calculated out of y.
and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.
so,
y = -9x + 2
y - 2 = -9x
x = -(y - 2)/9 = (-y + 2)/9
=> for a formal function definition
y = (-x + 2)/9
Answer:
The cost of each slice of pizza is $ 14.5
Step-by-step explanation:
Given as :
The combined total of 2 slices and 1 drink cost = $ 31.50
The price of each drink = $ 2.50
Let The number of slices = S
The number of drink = D
According to question
2 × S + 1 × D = $ 31.50
∵ 1 drink cost $ 2.50
So, 2 × S + 1 × D = $ 31.50
Or, 2 × S + 1 × $ 2.50 = $ 31.50
Or, 2 × S = $ 31.50 - $ 2.50
Or , 2 × S = $ 29
∴ S = = $ 14.5
Hence The cost of each slice of pizza is $ 14.5 Answer
Formulas
Step-by-step explanation:
Formulas are all unique and share the common trait of "x" and "y" values and a common purpose of helping you find the x and y value and/or answer to your question.
