Write an equation of the line that passes through the point (6,-9) with the given slope m= 3
Answer:
y = 3x - 27
Step-by-step explanation:
Since the slope is three, that is the only one that can be the answer.
answer: y = 3x - 27
explanation:
equation of a straight line: y = mx + c
( m is the slope and c the y- intercept )
here m = 3 , then y = 3x + c ← is the partial equation
to find c substitute (6, - 9) into the partial equation
-9 = 18 + c ⇒ c = -9 - 18 = - 27
y = 3x - 27 ← equation of line

How many different orders of top-three finishers are possible?
Drag the tiles to the correct locations on the equation. Not all tiles will be used.
Using the permutation formula, it is found that the number of different orders of top-three finishers that are possible is given as follows:
[tex]nPr = \frac{14!}{11!} = 2184[/tex].
The order in which the cars finish is important, hence the permutation formula is used instead of the combination formula.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]nPr = \frac{n!}{(n-r)!}[/tex]
In this problem, 3 cars are taken from a set of 14, hence the number of different orders is given as follows:
[tex]nPr = \frac{14!}{11!} = 2184[/tex].

225°
235°
Based on the information provided, the sum of all the labeled angles is 235° (option b).
How to calculate the sum of all labeled angles?To calculate the sum of all the labeled angles we must add the different values of each labeled angle as shown below:
80° + 92° + 40° + 23° = 235°
According to the above, it can be inferred that the correct option is B because the result of the sum of the values coincides with this sum.

Answer:

Step-by-step explanation:
Given:
Mike is buying eight tickets for a concert.
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
To Find:
What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.
Solve:
Since we know that:
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
Hence we know that 5 + 3 = 8
Thus,
$74.45 = 5 tickets
Now for the 3 tickets we can do individual tickets which cost $17.25
$17.25 × 3 = 51.75
Then we add both together:
51.75 + 74.45 = $126.20

Write the equation for the line in slope-intercept form.
Answer:
y=[tex]\frac{2}{3}x[/tex]+4
Step-by-step explanation:
[tex]\frac{rise}{run}[/tex]
plus the y intercept
which is 4
The required equation in slope-intercept form is y = - [tex]\frac{2}{3}[/tex]x + 4
What is an equation?An equation represents any two expressions or statements are equal that means they are having an equal to (=) sign in brtween them.
What is slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept is called slope-intercept form of the equation.
How to find the slope ?Slope of a line is the inclination of the straight line towards x axis.
If a straight line passes through two points (a , b) and (c , d), then slope(m) of the straight line can be calculated by the formula,[tex]m = \frac{d - b}{c-a}[/tex]
According to the problem, the straight line passes through (6 , 0) , (3 , 2) , (0, 4) , (-3 , 6).
Slope (m) = [tex]\frac{2-0}{3-6}[/tex] = - [tex]\frac{2}{3}[/tex]
How to write the equation in slope-intercept form?The equation can be written as
y = - [tex]\frac{2}{3}[/tex]x + b
Now , this line passes thorugh (0,4). So, (0,4) will satisfy the equation∴ putting (0,4) in the equation, we get,
y = 4
∴ The required equation is y = - [tex]\frac{2}{3}[/tex]x + 4.
For check we can satisfy the point ( -3 , 6) in the equation.- [tex]\frac{2}{3}[/tex](-3) + 4 = 6
CLearly, the point satisfies the equation.
So, the equation y = - [tex]\frac{2}{3}[/tex]x + 4 is correct

we have 23 marbles: 6 red marbles, 5 green marbles, 3 blue marbles, and 9 yellow marbles. We are drawing one marble from the bag. What is the probability of drawing a red or a yellow marble?
Answer:
15/23
Step-by-step explanation:
What is probability?
Probability in simple terms is the likelihood of something happening.
We can say that probability = # of favorable outcomes ( what we want to happen ) / total # of outcomes ( simply what's expected to happen )
Here, we want to find the probability of drawing a red or yellow marble.
So # of favorable outcomes = drawing a red or yellow marble and total # of possible outcomes would be simply the total number of marbles
Given:
There are 23 marbles totalThere are 9 yellow marbles There are 6 red marblesGiven this we can determine what the # of favorable outcomes are as well as how many total marbles are.
So in total there are 23 marbles, so total number of outcomes = 23
And there are 6 red marbles and 9 yellow marbles, so number of favorable outcomes = 6 + 9 = 15
Plugging these values into the probability formula we get 15/23
So the probability of drawing a red or yellow marble would be 15/23
Answer:
P(red or yellow marble)= 15/23
Step-by-step explanation:
If we have 23 marbles in the bag, 6 red and 9 yellow, we add the 6 and 9 to get 15. So there are 15 marbles that are red/yellow out of the 23 in the bag. This means the probability is 15/23. Hope this helps <3

working alone, either Johanna or Elizabeth can prepare the solution in six minutes. Dan can
prepare the solution in four minutes if he works alone. How many minutes will it take the thre

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.
What is the together rate?It is the sum of each separate rate.
In this problem, the rates are given by:
Johanna's: 1/6.Elizabeth's: 1/6.Dan's: 1/4.Hence the together rate is given by:
[tex]\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}[/tex]

When this number is subtracted from its square
x - x²
In order to find the greatest number, use vertex formula: x = -b/2a

this could be a rectangle.
to be safe, I am following that path.
in a rectangle opposite sides are of equal length.

y = 2y - 6
0 = y - 6
