Answer: 2/3x - 5
Step-by-step explanation:
The equation of a line passing through the given points is y = 2x/3-3
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, a line is passing through the points (3, -3) and (6,-1)
We know that, the equation of a line passing through two points is given by,
y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)
Therefore,
y+1 = (-1+3)/(6-3)(x-3)
y+1 = 2/3(x-3)
y = 2x/3-2-1
y = 2x/3-3
Hence, The equation of a line passing through the given points is y = 2x/3-3

What is the magnitude and direction angle of vector c?
|c| = 5, θ = 36.9°
|c| = 5, θ = 53.1°
|c| = 25, θ = 16.3°
|c| = 25, θ = 73.7°
Answer:
D
Step-by-step explanation:
The magnitude is 25 and the direction angle of vector c is 73.7°. Option D is correct.
Given, a=⟨2,10⟩, b=⟨-5,-14⟩, c=a-b
We need to find what is the magnitude and direction angle of vector c.
What is the magnitude and direction angle?Given a position vector v=⟨a,b⟩, the magnitude is found by |v|=√a²+b². The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application. For a position vector, the direction is found by tanθ=(ba)⇒θ=[tex]tan^{-1}[/tex](ba).
Now, vector c=⟨7,24⟩|c|=[tex]\sqrt{7^{2} +24^{2} }[/tex]=25angle =tan(θ)=(168)⇒θ=[tex]tan^{-1}[/tex](168)= 73.7°.
Hence, the magnitude is 25 and the direction angle of vector c is 73.7°.

Step-by-step explanation:
For its study, 195 randomly selected Southerners were surveyed and found to watch a mean of 4.5 hours of sports per week. In the North, 148 randomly selected people were surveyed and found to watch a mean of 4.7 hours of sports per week. Find a 99% confidence interval for the true difference between the mean numbers of hours of sports watched per week for the two regions if the South has a population standard deviation of 1.5 hours per week and the North has a population standard deviation of 1.7 hours per week.
Answer:
The 99% confidence interval for the true difference between the mean numbers of hours of sports watched per week for the two regions is = [ CI [-0.254, 0.654].
Step-by-step explanation:
The confidence interval for the true difference between the mean formula is given as:
μ1 - μ2 ± z × √(σ²1/n1 + σ²2/b2)
μ1 = Mean 1 = 4.5 hours
μ2 = Mean 2 = 4.7 hours
z = z score for 99% confidence interval = 2.576
σ1 = Standard deviation 1(South) = 1.5 hours
σ2 = Standard deviation 2(North) = 1.7 hours
n1 = number of samples 1 = 195
n2 = number of samples 2 = 148
Confidence Interval
= 4.5 - 4.7 ± 2.576 × √1.5²/195 + 1.7²/148
= 0.2 ± 2.576 × √0.0115384615 + 0.019527027
= 0.2 ± 2.576 × √0.0310954885
=0.2 ± 0.4542495969
Confidence Interval
= 0.2 - 0.4542495969
- 0.2542495969
= -0.254
Approximately = -0.654
= 0.2 + 0.4542495969
= 0.6542495969
Approximately = 0.654
Hence, The 99% confidence interval for the true difference between the mean numbers of hours of sports watched per week for the two regions is = CI [-0.254, 0.654].]

Part 2 Directions: Solve the matrix equation for "X" and "y" 5 - 2x 6 1 -8 + 2 -8 4. - 13 -13
Answer:
The value of x=9 and value of y= -7
Step-by-step explanation:
We need to solve the matrix equation for x and y
We are given:
[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +2\left[\begin{array}{cc}5&-1\\y&6\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
First multiply 2 with terms inside the matrix
[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +\left[\begin{array}{cc}10&-2\\2y&12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
Now adding matrices on left side
[tex]\left[\begin{array}{cc}-2x+10&6-2\\1+2y&-8+12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right]\\\left[\begin{array}{cc}-2x+10&4\\1+2y&4\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]
Now both sides are equal , so we can say that
[tex]-2x+10=-8 \ and \ 1+2y=-13[/tex]
Solving equations and finding values of x and y
Finding value of x
[tex]-2x+10=-8 \\-2x=-8-10\\-2x=-18\\x=\frac{-18}{-2}\\x=9[/tex]
Finding value of y
[tex]1+2y=-13\\2y=-13-1\\2y=-14\\y=\frac{-14}{2}\\y=-7[/tex]
So, value of x=9 and value of y= -7

14x+42=35
14×=35-42
14× = -7
×= -7/14
×= -1/2
Answer:
A
Step-by-step explanation:
Given f(x) = 14x + 42 and f(x) = 35, then equate right sides, that is
14x + 42 = 35 ( subtract 42 from both sides )
14x = - 7 ( divide both sides by 14 )
x = - [tex]\frac{7}{14}[/tex] = - [tex]\frac{1}{2}[/tex] → A

/10 /10
x=3
Your Answer is
x=3Hope This Helps! Brainliest Would Be Greatly Appreciated.Answer:
x=3
Step-by-step explanation:
the first step is to subtract 2 from both sides because you want to isolate the variable, and the opposite of addition is subtraction. so, you do 10x + 2 = 32, and when you subtract 2 from both, you get 10x = 30. then, because 10 and x are being multiplied together, you want to divide both sides by 10 to get x alone. so, you get x = 30/10, so x = 3.
If a person wanted to purchase their dream car, and keep it for many years, should they lease or buy? why?
Answer:
buy
Step-by-step explanation:
If a person wanted to buy their dream car and keep it for several years they would buy it since they wouldn't have to pay rent on the care even after they payed it off. If they were to lease they would have to pay rent for it.
If a person wanted to purchase their dream car, and keep it for many years, what they should is to: buy.
What is Leasing and buying?Leasing can be defined as an agreement in whereby the lessor or the owner give out his or her property to the lessee, in which the lessen is expected to payback the lessor periodical till the full payment is made.
While buying is simply to purchase a product in exchange for cash or money.
If a person wanted to purchase a car so as to keep it for many years, the best choice is to buy instead of leasing.
The reason why buying the car would be the better option is because the overall cost of buying the car would be lesser.
After paying for the car, the owner tend to gets much more value from the car.
Inconclusion the person should buy the car.

1. Evaluate the following numerical expressions. Problem Set a. 2+(-3) +7 b. )-4-1 d. -10 = 2 + 3 C. Ni 2x2 e. (8) + 2 f. 3+(-4)-1 2. Which expressions from Exercise 1 are equal?
Answer:
A equals 12
B equals 3
C equals 3+2+(-5)
E equals 4 NI
F equals -7+(-12)=19
Step-by-step explanation:
For A, you have to do the parenthesis first. I did 2+(-3) which equals -5. Then, I added the 7 to the five and got 12. The reason that it is not 12 is because the +7 is greater than the -5.
For B, I got -3 because -4 - (-1) equals 3. The reason that it is three is because when you look at the positive negative chart, you can see that negative and negative equal positive. So, the answer would be 3.
For E, I got 4 NI because when I multiplied the 2*2 I got 4 then you add the numerals Ni. I am not 100% on this problem, that is kind of my guess.
Finally for F, I got 19. My equation above explains it. Once again, you have to add the parenthesis first, so, -7+(-12) equals 19. Like I said above. If you look at the negative positive chart, the number would be positive because both numbers are negative.
I forgot C above, so here it is. For C, I got the equation above by putting the numbers together. For instance, in the problem on the side, for C, it says -10=3+2. If you just add 3+2, you are going to get 5. I added negative five to it and there you go, you get negative ten.
The first and second problems are equal because 3 goes into 12 equally.

Answer:
The 3 odd, consecutive numbers are 25, 27, and 29.
Step-by-step explanation:
When you add these 3 numbers you will get 81.
25 + 27 = 52
52 + 29 = 81
Therefore, 25 + 27 + 29 = 81
Hope this helps!!
Answer:three consecutive odd numbers are 25; 27; 29
suppose: the smallest number is x ( x > 0),(x ∈ N)
because 3 numbers are three consecutive odd numbers
=> The next 2 terms respectively are x + 2; x + 4
have: The sum of three consecutive odd numbers is 81
=> x + x + 2 + x+ 4 = 81
⇔ 3x + 6 = 81
⇔ 3x = 81 - 6
⇔ 3x = 75
⇔ x = 25
=> three consecutive odd numbers are 25; 27; 29
