It is possible to find f(x+7) by replacing each occurrence of
X by X+7
It is possible to find f(x+7) by replacing each occurrence of x in the function f(x) = x² - 5x + 4 and the function f(x + 4) becomes f(x + 4) = x² +3x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(x) = x² - 5x + 4
It is required to find the f(x + 4)
Replace x with x + 4
f(x + 4) = (x + 4)² - 5(x + 4) + 4
f(x + 4) = x² + 8x + 16 - 5x - 20 + 4
f(x + 4) = x² +3x
The function f(x + 4) is f(x + 4) = x² +3x after plugging x = x + 4 in the f(x)
Thus, it is possible to find f(x+7) by replacing each occurrence of x in the function f(x) = x² - 5x + 4 and the function f(x + 4) becomes f(x + 4) = x² +3x.

A square window has an area of x2 + 22x + 121 square feet. Find the length of one side of the square.
A) (x + 11) feet
B) (x – 11) feet
C) (x – 6) feet
D) (x + 6) feet
x + 11 ft
Step-by-step explanation:
x² + 22x + 121 ft² = area of square
x² + 11x + 11x + 121 ft² = side²
x(x + 11) + 11(x + 11) ft² = side²
(x + 11)(x + 11) ft² = side²
(x + 11)² ft² = side²
x + 11 ft = side²

Suppose that a number written as a decimal has an infinite number of non-repeating digits after the decimal point. What is this number called?
Oirational
natural
unnatural
rational
Hell yall
Answer:
Irrational
Step-by-step explanation:
The number is called an irrational number.
These numbers have some distinct properties. The number of numbers after the decimal point is infinite. What this means is that it does not terminate. It keeps on repeating.
Also, these numbers cannot be represented as a ratio of two integers i.e two whole numbers. This is because they keep on going without termination.
Lastly is that these numbers do not repeat after decimal. What I mean by this is that they do not keep repeating a particular number after the decimal point. For example in cases like 2.33333; these are infinite too, but they can be represented by the ratio of two whole numbers and in such cases, they are not irrational in their own respect
You and your friend each purchase an equal number n of magazines. Your magazines cost $1.50 each and your friend's magazines cost $2 each. The total cost for you and your friend is $10.50. Write and solve an equation to find the number of magazines you purchased.
Given:
You and your friend each purchase an equal number n of magazines.
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Total cost = $10.50
To find:
The equation to find number of magazines you purchased.
Solution:
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Number of magazines purchased by you and your friend = n
Total cost = [tex]1.50n+2n[/tex]
It is given that total cost is $10.50.
[tex]1.50n+2n=10.50[/tex]
[tex]3.50n=10.50[/tex]
Divide both sides by 3.50.
[tex]n=\dfrac{10.50}{3.50}[/tex]
[tex]n=3[/tex]
Therefore, required equation is [tex]1.50n+2n=10.50[/tex] and the number of magazines purchased by you is 3.
In the figure, m<7 = 100. Find the measure of <9.
As < 7 and angle < 9 are alternate interior angles, their sum will be equal .
Which means :-
[tex] < \: 7 = < \: 9[/tex]
[tex] < 9 = 100°[/tex]
Therefore , the value of <9 is 100° .
The magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.
What are parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is ∠7 = 100°.
The lines u and t are parallel to each other. The alternate interior angles are equal in magnitude. From the figure it is clear that ∠7 and ∠9 are alternate interior angles. Therefore, we can say that ∠7 = ∠9 = 100°.
Therefore, the magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.

Step-by-step explanation:
Cypress Middle School wants to have a fundraiser to buy art supplies. Fundraiser A will give the school $1.50 for each order placed plus $75 as a bonus. Fundraiser B will give the school $3.00 for each order placed, but no bonus. How many orders must be placed in order for the total amount of money earned by each fundraiser to be the same? a 150 b.5 c.17 d.50
Answer:
50
Step-by-step explanation:
Let the number of orders required be x
Fund raiser A , 1.50 for each other plus bonus of 75
for x orders, we have 1.50 * x = 1.50x
Add the bonus = 1.50x + 75
Fund raiser B, $3 for each other , no bonus
Total from fund raiser B is 3 * x = 3x
So to make them equal, we ensure that e equate both values;
3x = 1.5x + 75
3x -1.5x = 75
1.5x = 75
x = 75/1.5
x = 50
50 orders will make both funds equal

Which equation represents the vertical asymptote of the graph?
There is a hidden electric fence of sorts where the graph slowly approaches this vertical line but never touches or crosses it. It might help to draw in a dashed vertical line through -8 on the x axis.
A vertical asymptote occurs when a division by zero error happens. For instance, the equation y = 1/(x+8) has a division by zero error when x = -8 since x+8 = -8+8 = 0 is in the denominator.
Angle Z is 21 degrees larger than twice the measure of angle T. If ∠Z and ∠T are supplementary, what is the measure of angle T? *
angle T = x
angle Z = 2x + 21
We know that supplementary angles add up to 180 degrees.
180 = x + 2x + 21
Combine like terms.
180 = 3x + 21
Subtract 21 from both sides.
159 = 3x
Divide both sides by 3
53 = x
angle T = 53 degrees

Prove that: (1 + cos A)^2 - (1 - cos A)^2/
sin^2 A=
4cosec A. cotA
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]
Consider the left side
[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator
= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]
= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]
= [tex]\frac{4cosA}{sin^2A}[/tex]
= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]
= 4cosecAcotA

At a convenience store, you have a choice of five diet drinks, 10 regular drinks, six bags of fat-free chips, and 10 bags of regular chips. What is the probability that you will buy a regular drink and a regular bag of chips?
Answer:
I guess that the purchase is at random, then let's see the possible options:
5 diet drinks.
10 regular drinks.
Total drinks = 15
6 bags of fat-free chips
10 bags of regular chips.
Total chips = 16.
Probability of buying at random, a regular drink is equal to the number of regular drinks divided the total number of drinks:
p1 = 5/15 = 1/3
Probability of buying at random a regular bag of chips, we use the same reasoning as before.
p2 = 6/16 = 3/8
The joint probability will be equal to the product of the individual probabilities:
P = p1*p2 = (1/3)*(3/8) = 1/8.
Answer:
the answer is 5/12

The height above the surface of the Earth (in meters) of a rock thrown into the air at 10 m/s after x seconds is given by f(x)=−9.8x2+10x+1.5. On the surface of the moon, the height is given by g(x)=−1.6x2+10x+1.5. How much higher does the rock travel on the moon than on Earth? The rock travels about __ meter(s) higher on the moon than on Earth.
Answer:
Rock travels about 8.2x²meters higher on the moon than on the Earth.
Step-by-step explanation:
Expression showing the height of a rock thrown into the air at Earth is,
f(x) = -9.8x² + 10x + 1.5
Similarly, expression showing the height of rock thrown on the moon is,
g(x) = -1.6x² + 10x + 1.5
Difference in the height of the rock thrown on moon = g(x) - f(x)
= (-1.6x² + 10x + 1.5) - ( -9.8x² + 10x + 1.5)
= -1.6x² + 9.8x² + 10x - 10x + 1.5 - 1.5
= 8.2x²
Therefore, rock travels about 8.2x²meters higher on the moon than on the Earth.

h-(-2.22)=-7.851 solve for h
Answer:
[tex]\boxed {h = -10.071}[/tex]
Step-by-step explanation:
Solve for the value of [tex]h[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
[tex]h + 2.22 = -7.851[/tex]
-Subtract both side by [tex]2.22[/tex]:
[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]
[tex]\boxed {h = -10.071}[/tex]
So, the value of [tex]h[/tex] is [tex]-10.071[/tex].
