Answer:
14
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(8 + 20) / (5 - 3)
28 / 2
= 14
So, the slope is 14.

Use the Remainder Theorem.
Answer:
If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.
actually this factors by grouping:
f(x)=x³+3x²-x-3
= x²(x+3)-1(x+3)
=(x+3)(x²-1)
=(x+3)(x-1)(x+1) // difference of squares

Step-by-step explanation:
A standard deck of cards is purchased, and the deck includes 3 jokers. This means if the jokers are included, the deck contains 5 5 cards. Teresa is playing a game in which she is dealt 8 cards from a deck that includes the jokers. What is the probability that Teresa's hand includes at least one joker?
Answer:
The probability is [tex]0.3819[/tex]
Step-by-step explanation:
We know that Teresa is playing a game in which she is dealt 8 cards from a deck that includes 3 jokers and 52 common cards (a total of 55 cards).
Let's define the following random variable :
[tex]X[/tex] : '' Number of jokers in the hand of Teresa ''
We need to find [tex]P(X\geq 1)[/tex]
This probability is equivalent to :
[tex]P(X\geq 1)=1-P(X=0)[/tex]
[tex]P(X=0)[/tex] is the probability of having none jokers in the 8 card hand.
In order to find [tex]P(X=0)[/tex] we are going to count all the cases in which [tex]X=0[/tex] (given that we are in presence of an equally - likely sample space)
We calculate [tex]P(X=0)[/tex] as :
[tex]P(X=0)=\frac{\left(\begin{array}{c}52&8\end{array}\right)\left(\begin{array}{c}3&0\end{array}\right)}{\left(\begin{array}{c}55&8\end{array}\right)}[/tex]
We define the combinatorial number [tex]nCr=\left(\begin{array}{c}n&r\end{array}\right)=\frac{n!}{r!(n-r)!}[/tex]
In the denominator we have [tex]\left(\begin{array}{c}55&8\end{array}\right)[/tex] which represents all the ways in which we can extract 8 cards from the deck of 55 cards.
In the numerator we have the product of [tex]\left(\begin{array}{c}52&8\end{array}\right)[/tex] (which represents all the ways in which we can choose 8 cards from the 52 common cards) and [tex]\left(\begin{array}{c}3&0\end{array}\right)[/tex] (which represents that from the total of 3 jokers we extract 0)
If we perform the operation we find that :
[tex]P(X=0)=0.6181[/tex]
Finally,
[tex]P(X\geq 1)=1-P(X=0)=1-0.6181=0.3819[/tex]
The probability is [tex]0.3819[/tex]

Dustin's Lawn Care Service Customer Amount Paid Mrs. Schmitt $15.75 Mr. Jones $9.25 Mrs. Adams $22.50 Mr. Meyer $50.00 How much more does Dustin get paid to mow Mr. Meyer's lawn than to mow the other three lawns combined? Enter your answer in the box. I need helppppp!
Answer: $2.50
Step-by-step explanation:
The following payments are made by Dustin's Lawn Care Service Customer
Mrs. Schmitt = $15.75
Mr. Jones = $9.25
Mrs. Adams = $22.50
Mr. Meyer = $50.00
To get our answer, we need to add all the payments of the other three. This will be:
= $15.75 + $9.25 + $22.50
= $47.50
The answer will now be:
= $50.0 - $47.5
= $2.50
The ratio of boys to girls in a class is 5:6. How many boys are there if there are 33 students in the class?
Answer:
15.
explaination:
let x be the number which we have to times to the ratio.
(5+x) + (6+x) =33
5x + 6x =33
11x = 33
x=3
so we need to times 3 the ratio to get the actual number.
boys: 5 × 3 =15
girls:6 × 3 = 18
checking the answer: 15+ 18 = 33

daria bought a lemonade cup for $9 . each refill cost $2 . last month daria spent $31 on mug and refills . How many refills did she buy?
Answer:
Daria bought 11 refills of lemonade last month
Step-by-step explanation:
The equation is:
y = 2x + 9
The cup costs 9 dollars and is 2 dollars per refill
She spent 31 dollars so:
31 = 2x +9
Now we can solve!
2x + 9 = 31
Subtract 9 from both sides!
2x = 22
Divide both sides by 2!
x = 11
We know x is the amount of refills so,

What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
All the graphs are examined one by one as follows,
(A) In the graph A, The slope is negative.
Which implies the the speed will slow down.
(B) In the graph B, The slope is positive.
Which implies the the speed will rise up.
(C) ) In the graph C, The slope is zero.
Which implies the the speed will be constant.
(D) In the graph D, The slope is positive and it has a y intercept.
Which implies the the speed will rise from a non zero value.
Thus, in order to download a large file the suitable graph is (B).
Hence, the given case can be represented by graph B.

The dockland building in hamburg, germany is built in the shape of a parallelogram. What is the length of the flight of stairs that runs from the ground to the rooftop? Round your answer to the nearest meter. Show your work.
Answer:
The length of the flight of stairs is 52 m
Step-by-step explanation:
In parallelograms, opposite sides are equal in length
In the given figure
∵ The building is built in the shape of a parallelogram
∵ The length of the flight of stairs is one side of it
→ We can find it by finding the hypotenuse of the right triangle
whose legs are 47 m and 22 m
∴ The length of it = the length of the hypotenuse of the right Δ
→ By using the Pythagoras Theorem
∵ h = [tex]\sqrt{(leg1)^{2}+(leg2)^{2}}[/tex]
∵ leg1 = 47 and leg2 = 22
∴ h = [tex]\sqrt{(47)^{2}+(22)^{2}}[/tex]
∴ h = [tex]\sqrt{2209+484}[/tex]
∴ h = [tex]\sqrt{2693}[/tex]
∴ h = 51.89412298
∵ h represents the length of the flight of stairs
∴ The length of the flight of stairs = 51.89412298 m
→ Round it to the nearest meter
∴ The length of the flight of stairs = 52 m

What is a scale factor?
The ratio of weight of similar 2-D figures
The ratio of corresponding angles of similar figures
The ratio of corresponding sides of similar figures
The ratio of volume of similar 2-D figures
Answer:
Here is some helpful information from my mini lessons.
Step-by-step explanation:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.
Solve for x. 5(x - 3) + 4(x + 3) = 3(x - 1)
Answer:
x = 0
Step-by-step explanation:
5(x - 3) + 4(x + 3) = 3(x - 1)
5x - 15 + 4x + 12 = 3x - 3
5x + 4x + 12 - 15 = 3x - 3
9x - 3 = 3x - 3
9x = 3x - 3 + 3
9x = 3x
9x - 3x = 3x - 3x
6x = 0
6x ÷ 6 = 0 ÷ 6
x = 0
Answer:
5( x− 3 ) + 4 ( x +3)
9x − 3 = 3(x− 1 ) Simplify 3 ( x − 1 ) .
9 x − 3 = 3 x − 3
Move all terms containing x to the left side of the equation.
6 x − 3 = −3
Move all terms not containing x
to the right side of the equation.
6 x = 0
Divide each term by 6 and simplify.
x = 0
