Correct option is C, the correct equation is Y - 2 = -1/3 (x + 6).
Y=mx+b, where m is the slope and b is the y-intercept, is the slope intercept form. The graph of the linear equation can be drawn on the x-y coordinate plane using this form of the equation. Y = m x + b y=mx+b y=mx+by, equals, m, x, plus, b, where m is the slope and b is the y-intercept, is the slope intercept form.
Given points are (-6,2)
The required line should be perpendicular to y=3x-8.
When two lines are perpendicular,
their slopes are such that,
m1 = - 1/m2 [1]
⇒ slope of line 2 =
⇒ -1/3 [using (1) relationship ]
Now substituting the points are slope in the equation of line -
y - y₀ = m (x - x₀)
⇒ y - 2 = -1/3 (x + 6)
⇒ 3y - 6 = -x - 6
⇒ 3y + x = 0
⇒ x = -3y

A fair die is rolled 5 times. What is the probability of having no 1 and no 2 among the rolls
Answer:
40%
Step-by-step explanation:
There are 5 options to roll: 1, 2, 3, 4, and 5.
This means you have a 1 out of 5 chance of rolling each number.
This question is asking for 1 AND 2, not just one number. So, we have a 2 out of 5 chance of rolling that, because 2 options are acceptable instead of just one number.
I'm not sure which form you are looking for, but 2 out of 5 is the same as saying 2/5. Most probability solutions are wanted as a percentage. To find that just solve 2/5, which is 0.4. Move the decimal to the right twice, and that is a 40% chance.

What value makes the expressions equivalent? 8(-4x + 3) and - 14x + _ +(-18x）
The value that will 8(-4x+3) equivalent to -14x+ _+(18x) is 24
What are equivalent expressions?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
for example 2+ 3 and 4 + 1 are equivalent. The both have a value of 5.
Similarly;
8(-4x+3) , when the parentheses is opened, = -32x +24

Given f(x) = 3(x - 2)² + 4
The graph will be symmetrical to the y-axis and since a> 0, the parabola opens up.
The axis of symmetry is the line that divides a parabola into two symmetrical parts. The vertex is the point where the axis of symmetry intersects the parabola.
The axis of the symmetry is x=2
The vertex form of a parabola is y = a (x - h)²+ k
The vertex is given by (h,k) coordinates.
In order to find the vertex, we need to compare the given equation to the vertex form of the parabola.

How does the sum rule work?.
The formula for the sum rule is: P(A or B) = P(A) + P(B) - P(A and B)
The sum rule, also known as the addition rule of probability, states that the probability of any two events occurring together is the sum of the probability of each event occurring individually, minus the probability of them both occurring at the same time. The formula for the sum rule is:
P(A or B) = P(A) + P(B) - P(A and B)
where A and B are two events and P(A) and P(B) are the probabilities of each event occurring individually, and P(A and B) is the probability of both events occurring at the same time.
The sum rule is used when the two events are mutually exclusive, meaning that they cannot happen at the same time. In this case, P(A and B) = 0, so the formula becomes:
P(A or B) = P(A) + P(B)

In the absence of a diagram, lets use the one shown in the attached worksheet. The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries. The approach is to calculate areas for both the circle and the square.
Square = (11 cm)^2 = 121 cm^2
Circle = (3.14)*(14/2 cm)^2 = 153,9 cm^2
Subtract the square from the circle. That removes all the circle area, except for the four sections outside the square. The result is 32.9 cm^2

What is sequence?An ordered group of numbers or items is referred to as a sequence.Since each element in a series has a particular place in the sequence, the order of the elements is crucial.Sequences can either have a finite or infinite number of words, meaning they can either end or continue eternally.A formula that can be used to determine any term in a series given its location can be used to characterize sequences.a) To find a formula for the sequence, we can use a difference table.
First, let's write out the first few terms of the sequence:
3, 14, 32, 60, 98, ...
Next, we'll create a difference table:
n | Term | Difference
1 | 3 |
2 | 14 | 11
3 | 32 | 18
4 | 60 | 28
5 | 98 | 38
We see that the difference is increasing by 10 each time, so our formula can be written as:
Term = 11n + 3
To check the formula, we can plug in a few values of n and see if it matches the terms in the sequence:
n = 1, Term = 11(1) + 3 = 14
n = 2, Term = 11(2) + 3 = 32
n = 3, Term = 11(3) + 3 = 60
The formula matches the terms in the sequence, so it is correct.
b) To find the next three terms in the sequence, we can use our formula:
n = 6, Term = 11(6) + 3 = 79
n = 7, Term = 11(7) + 3 = 90
n = 8, Term = 11(8) + 3 = 101
So the next three terms in the sequence are 79, 90, and 101.

What is the solution to the system of equations y 2x 3. 5 and x 2y =- 14?.
The point (7, 10.5) is on the graph of both equations and satisfies the system of equations.
To find the solution to a system of equations, we need to find the values of x and y that satisfy both equations simultaneously.
The system of equations is:
y = 2x - 3.5
x - 2y = -14
We can begin by solving one of the equations for one of the variables, for example, we can solve the first equation for y:
y = 2x - 3.5
Next, we can substitute this expression for y into the second equation:
x - 2(2x - 3.5) = -14
This gives us:
x - 4x + 7 = -14
-3x = -21
x=7
Now we can substitute this value of x back into the first equation to find the corresponding value of y:
y = 2(7) - 3.5
y = 10.5
So the solution to the system of equations is x = 7, y = 10.5.

The theater sells two types of tickets: adult tickets for $11 and child tickets for $3.
Last night, the theater sold a total of 464 tickets for a total of $3520. How many adult tickets did the theater sell last night?
The adult tickets sold were 409.
What number of total adult ticket were sold?11a + 3c = 3520
Where "a" is the number of adult tickets sold and "c" is the number of child tickets sold.
We also know that the theater sold a total of 464 tickets, so we can add the following equation:
a + c = 464
We can now use the first equation to solve for one of the variables, and then substitute it into the second equation:
11a + 3c = 3520
3c = 3520 - 11a
c = (3520 - 11a)/3
We know that:
a + c = 464
We can substitute the value of c into this equation:
a + (3520 - 11a)/3 = 464
a + (3520 - 11a) = 464*3
a + 3520 - 11a = 1392
12a = 4912
a = 4912/12
a = 409
So, the theater sold 409 adult tickets last night
