cestrela7 [59]2 years ago
3 0

Answer:

C

Step-by-step explanation:

swap y and x in the function. that is

x = f(y)

we get x=4y+5

<em>S</em><em>o</em><em>l</em><em>v</em><em>e </em><em>for </em><em>y</em>

(x-5)/4=y

f ^{ - 1}(x) =  \frac{1}{4}  (x - 5)

What is an equation of the line that passes through the point (3,-1) and (8, 9)?
Evgesh-ka [11]

Answer:

4) y = 2x - 7

Step-by-step explanation:

First we have to find the slope by using the following formula....

let (3, - 1) be (x_{1}, y_{1} ), let (8, 9) be (x_{2} ,y_{2} ), and m be the slope, then....

m = \frac{y_{2} -y_{1} }{x_{2} - x_{1} } = \frac{9 + 1}{8 - 3} = \frac{10}{5} = 2

Now that we know the slope we can find the equation of the function by using point-slope for of the function which look like this.....

y -y_{1} = m(x - x_{1} )\\y + 1 = 2(x - 3)\\y + 1 = 2x - 6\\y = 2x - 7

Organize the following polynomial expressions from least to greatest based on their degree: x 2xyz 3x y z 2x3y y2x − 3x 4 9x3yz
bazaltina [42]

Using polynomial concepts, it is found that the sorting of the polynomial expressions from least to greatest based on their degree is given by: I, III, II, IV.

<h3>What is the degree of a polynomial?</h3>

The degree of a polynomial is given by it's largest exponent.

In this problem, the <em>polynomials </em>are given by:

  • I: x + 2xyz.
  • II: 9x³y².
  • III: 18x² + 5ab - 6y
  • IV: 4x^4 + 3x^2 - x - 4

Hence, the respective degrees are: 1, 3, 2, 4, and the ordering from least to greatest is: I, III, II, IV.
