Answer:
f(x)=x+2 Passes through
x-y=2 DOES NOT pass through
Step-by-step explanation:
Method- plug in x and see if the y matches the points. (1,3) (7,9)
f(x)=x+2
f(1)=1+2=3
f(7)=7+2=9
Matches!
x-y=2
1-y=2 --> y=-1

P(x) = x³- 2x² + 5x.
factor p completely
Answer:
P(x) = x (x²- 2x + 5)
Step-by-step explanation:
First factor x out:
P(x) = x (x²- 2x + 5)
Then, try to simplify (x²- 2x + 5):
However, there is no way to further simplify.
So, the answer should be x (x²- 2x + 5).
The lateral surface area of cone A is equal to the lateral surface area of
cylinder B.
A
2h
A. True
B. False
The lateral surface area of cone A is equal to the lateral surface area of
cylinder B. This is true.
How to illustrate the information?Lateral area of cone is given by: πrl
where r is the radius and l is the slant height
Here r=r and l=2h
Hence, lateral area of cone A= π×r×2h = 2πrh
Lateral area of cylinder is given by: 2πrh
where r is the radius and h is the height
Lateral area of cylinder B=2πrh
Clearly, both the lateral areas are equal. Therefore, it's true.

For a set of five numbers,
the mode is 8
the median is 12
Work out one possible set of five numbers.
Step-by-step explanation:
mode = the number appearing the most often in the list of data.
median = the middle number. half of the other numbers are smaller, and the other half is larger.
so, we know one number already : 12 in the middle.
that gives us
_ _ 12 _ _
a good mode is when it has a real majority (e.g. every other number appears only once, but the mode number appears twice).
so, 8 should appear twice.
as 8 is smaller than 12, it can only be on the left side of 12.
that gives us
8 8 12 _ _
note we need 2 numbers larger than 12, but each appearing only once.
so, e.g.
8 8 12 13 14

Answer:
x = √141

x = 11.87
Step-by-step explanation:
is a right triangle, we solve it with the Pythagorean theorem ("In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".)
x² = 25² - 22²
x² = 625 - 484

The number of cupcakes Chad can eat is 2 times the amount his sister can eat. On Chad’s
birthday Chad and his sister ate a total of 12 cupcakes? How many did Chad eat?
The number of cupcakes that Chad are is 8 cupcakes.
What is an equation?A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Let the number of cupcakes that Chad can buy be x.
The number of cupcakes Chad can eat is 2 times the amount his sister can eat. This will be 2x.
Therefore, the appropriate equation will be:
2x + x = 12
3x = 12
Divide
x = 12/3
x = 4
Chad = 2x = 2 × 4 = 8 cupcakes

4. Find all values of x that make the statement true.
By solving ( 3 / x - 4) = (x - 5) / x equation we get ,
x = 10 and x = 2 .
Solution:
Given ( 3 / x - 4) = (x - 5) / x,
3x = (x - 5) (x - 4)
By solving this equation,
3x = x( x - 5 ) - 4( x- 5)
3x = x² - 5x - 4( x - 5)
3x = x² - 5x - 4x + 20
3x = x² - 9x + 20 = 0
3x - x² + 9x -20 = 0
12x - x² - 20 = 0
-x² + 12x -20 = 0
-1(x(x - 2 ) - 10( x - 2 )) = 0
-1( x - 10) ( x - 2) = 0
x - 10 = 0
x - 2 = 0
∴ x = 10

How many times larger is (1.76 x 10^1) than (8 x 10^-1)
Answer:
14.7 times bigger is (1.176 x 10¹) than (8 × 10-¹) if the numbers are (1.176 x 10¹) than (8 × 10-¹).
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
To compare numbers this way, we divide.
(1.76 × 10^1) / (8 × 10^-1) =
= 1.76/8 × 10^1 / 10^-1
= 0.22 × 10^(1 - (-1))
= 0.22 × 10^2
= 22

A) 11 + 6x = 22
B) 3x + 1 = 9
C) 18−2x=9
D) 25/x+4=9
E) x/5 + 5 = 6
F) 32−4x=12
The equation that has the same solution as x = 5 are as follows:
25 / x + 4 = 9x / 5 + 5 = 6 32 - 4x = 12 How to solve equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
In other words, an equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation can be solved as follows:
The equation will have the same solution as x = 5.
Therefore,
25 / x + 4 = 9
subtract 4 from both sides of the equation
25 / x + 4 = 9
25 / x + 4 - 4 = 9 - 4
25 / x = 5
cross multiply
5x = 25
divide both sides by 5
x = 25 / 5
x = 5
x / 5 + 5 = 6
x / 5 = 6 - 5
x / 5 = 1
cross multiply
x = 5
32 - 4x = 12
- 4x = 12 - 32
- 4x = - 20
divide both sides of the equations by - 4
x = -20 / - 4
x = 5
Therefore, the equation with same solution are 25 / x + 4 = 9, x / 5 + 5 = 6 and 32 - 4x = 12

1. The public primary/secondary school dropout rate in Washington State is 6%. Suppose 35
individuals of primary/secondary school age are interviewed at random on a city street. What is
the probability that:
a. (5 points) Exactly 7 of them are dropouts?
The probability that exactly 7 individuals are dropouts out of 35 is 0.0033288.
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
Given,
Probability of dropouts=p= 6%= 0.06
Probability of not dropouts=q=1-p=1-0.06=0.94
n=35
We use the probability mass function of binomial distribution, as there are only two possible outcomes for the given situation. If the individual is dropout or not a dropout.
P(X=x)= nCr x p^r x q^(n-r)
P(X=7)= 35C7x(0.06)^7x(0.94)^28
P(X=7)=6724520x(0.06)^7x(0.94)^28
P(X=7)=0.00332889
Therefore, the probability of exactly 7 of them are dropouts is 0.00332889.
