divide (2x^2-5x-3) by (x-3)​

Answers

Answer:

2x + 1

Step-by-step explanation:

Answer:

The expression simplifies to [tex]2x+1[/tex]

Step-by-step explanation:

To divide the polynomials, we must first factor the trinomial into binomials so we can easily divide it by the binomial.  Factoring [tex]2x^2-5x-3[/tex] results in the expression [tex](x-3)(2x+1)[/tex].  Since these two values are multiplied, the [tex](x-3)[/tex] can be canceled out by the divisor, which is the exact same expression.  This leaves us with our final answer: [tex]2x+1[/tex].

3. What is the slope of 3y - 4x = 12?

Answers

Answer: (3,0)

Step-by-step explanation: x=0

3y=12

divide both sides by 3 you get

y=4   now you have y axis ( equation x=0) at the point its (0,4)

but if you put y=0 then you get

4x=12

and then x=3

so i think the answer is (3,0)

A radio station requires DJs to play 2 commercials for every 14 songs they play. What is the unit rate of songs to commercials? songs The unit rate is 1 commercial​

Answers

The correct answer for this question is that the unit rate is 5:1. We can work this out by simplifying down the 2 commercials to every 10 songs ration, so that 10:2 becomes 5:1. We can work this out by halving the original ratio to simplify it.

Compute the estimated regression's prediction for the average score of students given 98, 129, or 159 minutes to complete the exam.
Given 98 minutes, the estimated regression's prediction for the average score of students is 91.94 .
Given 129 minutes, the estimated regression's prediction for the average score of students is 108.37
Given 159 minutes, the estimated regression's prediction for the average score of students is 124.27 (Round your responses to two decimal places.)
Compute the estimated gain in score for a student who is given an additional 32 minutes on the exam.
The estimated gain in score for a student who is given an additional 32 minutes on the exam is (Round your response to two decimal places.)

Answers

Answer:

The estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96

Step-by-step explanation:

The estimated regression prediction is given by:

[tex]\hat{y}=40+0.53x[/tex]

Where x denotes the time

y denotes the average score

A)

Substitute x = 98

[tex]\hat{y}=40+0.53(98) = 91.94[/tex]

B)

Substitute x = 129

[tex]\hat{y}=40+0.53(129) = 108.37[/tex]

C)

Substitute x = 159

[tex]\hat{y}=40+0.53(159) = 124.27[/tex]

D)the estimated gain in score for a student who is given an additional 32 minutes on the exam.

[tex]\hat{y}=40+0.53(x+32)=40+0.53x+9.57=y+16.96[/tex]

So, the estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96
