Given that the point (-4,0) is on the graph f(x), find the corresponding point for the function f (4x)
Answer:
-24
Step-by-step explanation:
f(4) = 6
f(-4*4) = -4 * 6
-4*6
-24
9514 1404 393
Answer:
(-1, 0)
Step-by-step explanation:
We want the point (4x, f(4x)) to match (-4, 0). We already know that f(-4) = 0, so we want 4x = -4.
4x = -4
x = -1 . . . . divide by 4
The desired point is (-1, 0).
_____
Comment on f(4x)
The attached graph shows that f(4x) represents a horizontal compression of the graph of f(x) by a factor of 4. The point on f(4x) with the same y-value, the corresponding point requested by this question, is shown to be (-1, 0).
what is the inverse of the function f (x)=2x+1
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
[tex]\frac{y-1}{2}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

The measure of an angle is 55°. What is the measure of its supplementary angle?
Answer:
125
Step-by-step explanation:
El Angulo suplementario es cuando los ángulos sumados valen 180.
Ejemplo: Angulo suplementario de 15.
15+x=180
x=180-15
x=165
Entonces:
180=55+X
180-55=X
125=X

A small truck can hold a total of 40 crates and boxes. For every 3 crates the truck can hold, there is room for 5 boxes. How many crates and boxes are in the truck when it is completely full?
Answer: There are 25 crates and 15 boxes in the truck when it is full.
Step-by-step explanation:
Let c= Number of crates , b= Number of boxes.
As per given,
[tex]c+b = 40[/tex] (i)
[tex]3c=5b\\\\\Rightarow\ c=\dfrac{5b}{3}[/tex] (ii)
Put value of c from (ii) in (i)
[tex]\dfrac{5b}{3}+b = 40\\\\\Rightarrow\ \dfrac{5b+3b}{3}=40\\\\\Rightarrow\ \dfrac{8b}{3}=40\\\\\Rightarrow\ 8b=3\times40\\\\\Rightarrow\ 8b=120\\\\\Rightarrow\ b=\dfrac{120}{8}=15[/tex]
put value of b in (ii),
[tex]c=\dfrac{5\times15}{3}=5\times5=25[/tex]
Hence, there are 25 crates and 15 boxes in the truck when it is full.
25 boxes 15 crates
We would get this solution by adding up the two sides comparing the ratios, hence: we get room for 3 crates for every 5 boxes that we can hold in the truck.
What are ratios?A ratio is an ordered pair of numbers a and b, written a:b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. hence, if there is 3 crates and 5 boxes you could write the ratio as: 3 : 5 (for every 3 crates there are 5 boxes) 3 / 5 are boys and 5 / 3 are crates.

Jeff got 23/25 on his first math test, 93% on his second test, and a 0.89 on his third test. Which of the following orders his scores from least to greatest?
Answer:
0.89, 23/25, 93%
Step-by-step explanation:
1. Convert 23/25 to a decimal: 0.92; and then a percent: 92%
2. Convert 0.89 to a percent: 89%
3. Now, we can order these from least to greatest. In order they would obviously be 89, 92, and 93 percent.

The amount, in dollars, of Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account. How much did her mother contribute each month?
Answer:
$8
Step-by-step explanation:
5x / 5 = x
40 / 5 = 8
Marisa’s mother contribution was $8 each month.
What is an expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given that, Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account.
The amount in Marisa's account after 5 months = 5x + 40
She has saved $x each month for 5 months, therefore, her saving = 5x
Her mother given her an additional amount each month which is here shown by 40,
Since, if in 5 months it became 40, therefore, each month mother gave her = 40 / 5 = 8
Hence, Marisa’s mother contribution was $8 each month.

Each of Caleb's friends has the same number of pets. The total number of pets can be represented by the expression y plus y plus y plus y. Which is an equivalent expression for the total number of pets?
Given:
The total number of pets can be represented by the expression [tex]y+y+y+y[/tex].
To find:
The expression which is equivalent to the expression for the total number of pets.
Solution:
The expression for the total number of pets is
[tex]y+y+y+y[/tex]
On adding these value, we get
[tex]y+y+y+y=4y[/tex]
Therefore, the expression 4y is equivalent to the given expression for the total number of pets.
Which function is best represented by this graph?
A. y=1/4x + 8
B. y=1/4x - 2
C. y=4x +2
D. y=4x +8
Answer:
B. y=1/4x-2
Step-by-step explanation:
The -2 in this equation represents the y value. The graph passes through -2 on the y axis, so you automatically cancel out the rest of the answers.
Option B is correct, y=1/4x - 2 is the function which best represented by the given graph.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The line is passing through the points (0, -2) and (4, -1)
Let us find the slope m.
m = -1-(-2)/4
=1/4
So slope is 1/4
Now let us find the y intercept
-2=1/4(0)+b
-2=b
So equation will be y=1/4x-2
Hence, Option B is correct, y=1/4x - 2 is the function which best represented by the given graph.
