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

Answer:
[tex]x = −1.9434851[/tex]
Step-by-step explanation:
[tex]0.11 +1 2.74(x + 3) = 0.08 + 13.49 \\ 0.11 + 12.74x + 38.22 = 0.08 + 13.49 \\ 12.74x + 38.33 = 13.57 \\ 12.74x = 13.57 - 38.33 \\ 12.74x = −24.76 \\ \frac{12.74x}{12.74} = \frac{ - 24.76}{12.74} \\ x = −1.9434851[/tex]

During the 2017 Major League Baseball season, the Detroit Tigers played 162 games . They lost 34 more games than they won. What was the teams win-loss record? Help me please .
Answer:
win: 64
loss: 98
Step-by-step explanation:
win: x
loss: x + 34
win + loss = total games
x + x + 34 = 162
2x + 34 = 162
2x = 128
x = 64
win: 64

divide (2x^2-5x-3) by (x-3)
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].

An electrician charges a base fee of $65 plus $50 for each hour of work. The minimum the electrician charges is $165. Create a table that shows the amount the electrician charges for 1, 2, 3, and 4 hours of work. Determine the domain and range of the relation in context and explain whether or not this represents a function.
P.S The range values are repeated. So it's a total of 3 range values, and 1 is repeated.
Is there more information so that I solve?
Domain: hours worked
Domain Values: 1,2,3,4
Range: dollars charged
Range Values: 165, 215, 265
The relation is a function. Each domain value is paired with exactly one range value.
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.)
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
