f (x) = (-5,
a) Find f(1) =
(1) b) Find f(5) =
(1)
Answer:
f(1) = - 5, f(5) = 6
Step-by-step explanation:
(a)
f(1) with x = 1 is in the interval x ≤ 1 , thus
f(1) = - 5
(b)
f(5) with x = 5 is in the interval x > 1 , thus f(x) = 2x - 4 , so
f(5) = 2(5) - 4 = 10 - 4 = 6
if f(x)=x^2-5x+4, if is possible to find f(x+4) by replacing each occurrence of
Answer
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.

Are x(3x) and 4x equivalent?
Answer:
They are not equivalent.
Step-by-step explanation:
x(3x) = 4x
x by itself = 1x
1x ( 3x ) = 4x
1x times 3x = 3x
3x = 4x is not equivalent.

A string measures 30 centimeters. About how many inches long is the string?
A. 11
B. 11.8
C. 15
D. 20
Answer:
B
There are 2.54 centimeters to every inch.
30/2.54 is 11.8
The length of the string in inches in 11.8.
In order to determine the length of the string in inches, the unit of conversion of centimeters to inches have to be first determined. 1 centimeter is equivalent to 0.393701 inches.
1 cm = 0.393701 inches
The second step is to multiply the length of the string in centimeter by the unit of conversion.
Length of string x unit of conversion
30 x 0.393701
= 11.8 (to one decimal place).

For membership to an athletic club, it costs $110 to join and $25 per month of membership. Write an equation to show the situation
Answer:
110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)
Step-by-step explanation:
Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.

Please help! I am supposed to write a recursive and an explicit function for the geometric sequence but this one is really frustrating me. Thank you!
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.

Step-by-step explanation:
m+7−5=20
Step 1: Simplify both sides of the equation.
m+7−5=20
m+7+−5=20
(m)+(7+−5)=20(Combine Like Terms)
m+2=20
m+2=20
Step 2: Subtract 2 from both sides.
m+2−2=20−2
m=18

7. Which of the following statements about the line is TRUE?
B. The line has a positive slope.
C. The point (1,4) lies on the line.
D. This line is parallel to the line whose equation is y - 2x - 7.
Answer:
B
Step-by-step explanation:
the line has a positive slope. you can tell by comparing the equation of the line to y=MX+c where m=slope= coefficient of x.
In this case the coefficient of x is positive 3.

Point JJ is located at (5,-3)(5,−3) on the coordinate plane. Point JJ is reflected over the yy-axis to create point J'J ′ . Point J'J ′ is then reflected over the xx-axis to create point J''J ′′ . What ordered pair describes the location of J''?J ′′ ?
Answer:
[tex]J" = (-5,3)[/tex]
Step-by-step explanation:
Given
[tex]J = (5,-3)[/tex]
Reflections: over y and x axis to create J"
Required
Determine J"
When reflected over y axis:
[tex]J'(x,y) = J(-x,y)[/tex]
We have that:
[tex]J = (5,-3)[/tex]
So:
[tex]J(-x,y) = (-5,-3)[/tex]
Hence
[tex]J' = (-5,-3)[/tex]
When reflected over x axis:
[tex]J"(x,y) = J'(x,-y)[/tex]
We have that:
[tex]J' = (-5,-3)[/tex]
So:
[tex]J(x,-y) = (-5,3)[/tex]
Hence
[tex]J" = (-5,3)[/tex]

Look at attachment for graph.
Step-by-step explanation:
Solving the inequality just has us isolate the x value.
[tex]-9 + 2x < 1[/tex]
Add 9 to both sides to cancel out -9
[tex]2x < 10[/tex]
Finally, divide both sides by 2 to get rid of the 2 on the x.
[tex]x < 5[/tex]
To graph this, you will just add an open circle on 5 and shade every number to the left of it.
