Write the equation of the line that passes through the points (3,1)(3,1) and (-7,-1)(−7,−1). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.
Answer:
[tex]\textsf{Point-slope form}: \quad y-1=\dfrac{1}{5}(x-3)[/tex]
Step-by-step explanation:
Define the given points:
(x₁, y₁) = (3, 1)(x₂, y₂) = (-7, -1)Substitute the defined points into the slope formula to find the slope of the line:
[tex]\implies \textsf{Slope $(m)$}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{-7-3}-\dfrac{-2}{-10}=\dfrac{1}{5}[/tex]
Substitute the found slope and one of the points into the point-slope formula:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-1=\dfrac{1}{5}(x-3)[/tex]
Simplify to slope-intercept form, if necessary:
[tex]\implies y-1=\dfrac{1}{5}x-\dfrac{3}{5}[/tex]
[tex]\implies y=\dfrac{1}{5}x+\dfrac{2}{5}[/tex]
Fighting fires is a profession that is really heating up. The average firefighter works 160 hours a month and make $4,090 for the month. If you only work 32 hours in a week, how much will you make?
Working 32 hours a week will fetch you $818
How to calculate the amount you will make?From the question, the given parameters are:
Number of hours = 160
Earnings in a month = $4090
Start by calculating the unit rate
This is calculated using the following unit rate formula
So, we have
Unit rate = Earnings in a month/Number of hours
Substitute the known values in the above equation
So, we have
Unit rate = 4090/160
Evaluate the quotient
Unit rate = 25.5625
For 32 hours, the total earnings is
Total = Unit rate x Number of houts
So, we have
Total = 25.5625 x 32
Evaluate
Total = 818
Hence, you will earn $818 weekly

assume that for any given day, the probability of a sunny day is 80%, the probability of getting free pizza is 30%, and the probability of getting free pizza on a sunny day is 35%. a. what is the probability of a less than ideal day (no free pizza and no sun)?
The probability of a less-than-ideal day (no free pizza and no sun) is 0.25
Let us define the events from the example.
Let event A: Sunny day for any given day
event B: Getting free pizza for any given day.
Now, we will translate the word problem into our symbols.
The probability of a sunny day is 80% i.e P(A)=0.8
The probability of free getting pizza is 30% i.e. P(B) = 0.3
The probability of free pizza and a sunny day is 35% .i.e P(A∩B) = 0.35
a)Complement means not happening an event i.e. event A’ : No sunny day for any given day event B’: Not getting day free pizza for any given.
Here dash ( ‘ ) complement.
The probability of a less-than-ideal day
(no free pizza and no sun) is
P(A'∩B') = P(A∪B)'... (De Morgan's Jaw)
De Morgan's law: (A∩B)'= A'∪B'
(A∪B)’ = A'∩B'
P(A'∩B') = 1-P(A∪B) (P(A) = 1-P(A)).
= 1-[P(A) + P(B)-P(A∩B)]
= 1-[0.8+0.3-0.35]
P(A'∩B') = 0·25
The probability of a less-than-ideal day (no free pizza and no sun) is 0.25.
b)To check whether free pizza and sun are independent events or not, let us see when two events are said to be independent.
Two events (A & b) are said to be independent if P(A∩B) = P(A)· P(B)
Let us check whether this property satisfies our case or not.
LHS = P(A∩B)=0.35
RHS= P(A) P(B)
= 0.8 x 0.3
RHS = 0.24.
LHS ≠ RHS
P(ANB) ≠ P(A). P(B) in our case.
Two events A and B are not independent in our case
Sun and free pizza are not independent events.
c)Probability of no free pizza on a sunny day is P(A∩B').
P(A∩B') = P(A) - P(A∩B) = 0.8 0.35
P(A∩B') = 0·45
The probability of no free pizza on a sunny day is 0.45

Answer:
A' = (6, 3)
B' = (1, 1)
C' = (8, 7)
Step-by-step explanation:
Vertices of triangle ABC:
A = (2, -3)B = (-3, -5)C = (4, 1)Given mapping rule:
(x, y) → (x + 4, y + 6)
This notation tells you that the x-coordinate is translated 4 units to the right, and the y-coordinate is translated 6 units up.
Substitute the coordinates of each point into the mapping rule to find the vertices of triangle A'B'C':
⇒ A' = (2 + 4, -3 + 6) = (6, 3)
⇒ B' = (-3 + 4, -5 + 6) = (1, 1)
⇒ C' = (4 + 4, 1 + 6) = (8, 7)

What is meant by an equation?
An equation is a formula in mathematics that expresses the equality of two expressions by linking them with the equals sign. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Differential equations are equations in which one or more functions and their derivatives are involved. They are solved by locating a function expression that does not use derivatives. Differential equations are used to represent processes with variable rates of change in fields such as physics, chemistry, biology, and economics.

I am not sure how to find out if the number is an integer or not I don’t need you to answer all those number that are in the pic I want to understand how to figure that out on my own
An integer number is a number that can be written without using a rational component. In other words, if a number can be written without using a fraction, then that number is considered an integer.
For example, let's take the first number:
[tex]-\frac{64}{8}[/tex]This number is written as a fraction. But, this is also equivalent to:
[tex]-\frac{64}{8}=-8[/tex]Since it can also be written without making use of a fraction then this number is an integer.
Also, there are numbers that are written in decimal form. For example:
[tex]-8.92[/tex]These types of numbers are not integers.
Solve 2x + 32 + x = 17.
x = 5
x = 0.2
x = −0.2
x = −5
Please and thank you.
2x+32+x = 17
Combine 2x and X to get 3x.
3x+32 = 17
Subtract 32 on both sides.
3x = 17−32
Remains 32 of 17 to obtain −15.
3x = −15
Divide both sides by 3.
x = -15/3
Divide −15 by 3 to get −5.
x = −5
The last option is correct.The value of x after solving the given equation 2x + 32 + x = 17, is x = -5, which is the last option.
Given an equation:
2x + 32 + x = 17
It is required to find the value of x after solving or simplifying the equation.
In order to get the value of x, the equation has to be solved in such a way that the terms with the variable have to be placed on one side and the constant terms on the other side.
Consider:
2x + 32 + x = 17
Add x and 2x since they are like terms in variables.
3x + 32 = 17
Subtract 32 from both sides of the equation.
3x = 17 - 32
3x = -15
Divide both sides of the equation by 3.
x = -5
Hence, the value of x is -5.

Find the equation of a parabola with a focus at (-2,-3) and a directrix at y = -5
The equation of a parabola with a focus at (-2,-3) and a directrix at y = -5 is y = 1/7(x + 2)^2 - 8/7 vertex is (2, -8/7)
What is Parabola?
A parabola is the location of a moving point whose distance from a given focus point and directrix line, respectively, is always constant.
let's keep it simple: (x, y). Focus is on (7,5)
When the separation from focus is
[tex]\sqrt{(x - (-2)^{2}) + (y - (-3)^{2} ) }[/tex] . Its distance from directrix y = -5 i.e.
y + 5 = |y + 5|^2
Hence, equation of parabola:
(x - (-2))^2 + (y - (-3))^2 = |y + 5|^2
or, (x + 2)^2 + (y + 3)^2 = |y + 5|^2
x^2 + 4x + 4 + y^2 + 3y + 9 = y^2 + 10y + 25
or, x^2 + 4x + 13 + y^2 + 3y = y^2 + 10y + 25
x^2 + 4x - 12 = 7y
y = (x^2 + 4x - 12)/7
y = 1/7(x^2 + 4x +4 - 4) - 12/7
y = 1/7(x + 2)^2 - 12-4/7
y = 1/7(x + 2)^2 - 8/7
Hence, parabola's equation is y = 1/7(x + 2)^2 - 8/7 vertex is (2, -8/7)

The value of the unknown angle in the triangle is as follows;
m∠S = 40 degreesHow to find the angle of a triangle?The exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.
In other words, an exterior angle of a triangle is equal to the sum of the two opposite interior angles.
The external angle is ∠JRS.
Therefore, m∠S can be found as follows:
∠JRS = m∠S + m∠T
Hence,
m∠S = 3x + 4
m∠T = 8x + 4
∠JRS = 140°
Hence,
140 = 3x + 4 + 8x + 4
140 = 3x + 8x + 4 + 4
140 = 11x + 8
140 - 8 = 11x
132 = 11x
x = 132 / 11
x = 12
Therefore,
m∠S = 3(12) + 4 = 40 degrees.

There are 264 red marbles in a bag.
What is Marbles?
A marble is a tiny, sphere-shaped object that is frequently fashioned of agate, glass, clay, steel, or plastic. They come in a variety of sizes, but the most have a diameter of about 13 mm (12 in). These toys can be made into works of art or utilized in a variety of marble-based activities. They can also be used in races or runs. They are frequently collected for their pleasing colors and nostalgic appeal.
Let x = Number of red marbles
y = Number of black marbles.
A bag contains 275 marbles.
So, x + y = 275 ..(1)
There are 24 red marbles for every black marble.
x = 24y ..(2)
Plug value of x in equation (1).
24y + y = 275
