The table shows input and output values for a liner function f(x). What is the positive difference of outputs for any two outputs that are two values apart? H E L P. 10 Points award!!
Answer:
If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased,
the f(x) will be increased by 0.5. The graph function should be:
f(x)= x/2A positive difference means that the value should be always positive.
To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:
f(x+3) - f(x)f(3)- f(0)=1.5 - 0= 1.5The answer would be: 1.5

A web browser is open on your computer screen. The area of the browser window is 24 square inches. Find the length of the browser window x. The browser covers 3/13 of the screen. What are the dimensions of the screen?
We will see that the length of the browser window is 4.9 inches, and the screen is a square of sidelength 10.2 in
How to find the length of the browser window?
We know that the area of the browser window is 24 in^2, we will assume that the window is a perfect square, then the area is equal to the square of the length x, we have:
x^2 = 24 in^2
x = √(24 in^2) = 4.9 in
How to get the dimensions of the screen?We know that the browser covers 3/13 of the screen, so the area of the screen is 13/3 times the area of the browser:
A = (13/3)*24 in^2 = 104 in^2
Again, if the screen is square of sidelength s, we have:
s^2 = 104 in^2
s = √(104 in^2) = 10.2 in

Kiwi fruit contains roughly two and a half times as much vitamin C as the same weight of oranges.
What weight of kiwi fruit contains approximately the same amount of Vitamin C as 1kg of oranges
Using proportions, it is found that 400g = 0.4kg of kiwi fruit contains approximately the same amount of Vitamin C as 1kg of oranges.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Kiwi fruit contains roughly two and a half times as much vitamin C as the same weight of oranges. Hence, if there is 1 kg = 1000g of oranges, the weight of kiwi fruit is given by:

 which equation represents the line that passes through the points (3, 7) and (-1, -1)?
points: (3, 7) and (-1, -1)
slope (m) :
[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}[/tex]
========
[tex]\hookrightarrow \dfrac{-1-7}{-1-3}[/tex]
[tex]\hookrightarrow \dfrac{-8}{-4}[/tex]
[tex]\hookrightarrow 2[/tex]
Equation:
[tex]\sf y-y_1 = m(x-x_1)[/tex]
==============
[tex]\rightarrow \sf y-7 = 2(x-3)[/tex]
[tex]\rightarrow \sf y = 2x-6+7[/tex]
[tex]\rightarrow \sf y = 2x+1[/tex]
Answer:
[tex]y = 2x- 1[/tex]
Step-by-step explanation:
To determine which equation passes through the points (3, 7) and (-1, -1), we need to determine the slope of the equation. Then, we shall use point slope form to determine the equation of the line.
Determining the slope of the line:
[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run} } =\dfrac{\text{y}_{2} - \text{y}_{1} }{\text{x}_{2} - \text{x}_{1} }[/tex]
Substituting the points in the slope formula:
[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]
Simplifying the slope:
[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]
[tex]\text{Slope} =\dfrac{-8}{-4 } = 2[/tex]
Determining the equation of the line:
We shall use point slope form to determine the equation of the line.
[tex]\text{Point slope form:} \ y - y_{1} = m(x- x_{1} )[/tex]
Substitute the slope and the coordinates of any two points stated above.
[tex]y -7= 2(x- 3 ) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Using the point (3,7)}][/tex]
Simplify the equation and organize it to slope intercept form:
[tex]y -7= 2x- 6[/tex]
[tex]y = 2x- 6 + 7[/tex]
[tex]y = 2x+ 1[/tex]

Here, (h, k) is the vertex point.
The first three steps in writing the function in vertex form are shown.

A theater has 32 rows. The first row has 18 seats, second row has 21 seats, third row
has 24 seats, and so on. Determine the total number of seats in the theater.
Answer:
2064
Step-by-step explanation:
18 + 21 + 24 + ...
This is an arithmetic series with first term 18 and common difference 3.
The nth term is
18 + 3(n - 1)
The 32nd term is the number of seats in the 32nd row:
18 + 3(32 - 1) = 18 + 3(31) = 18 + 93 = 111
The sum of the series is:
n/2(a + L) = (32/2)(18 + 111) = 2064
Which equation is equivalent to n+4 = 11?
Answer:
n = 7
Step-by-step explanation:
n+ 4 = 11 subtract 4 from both sides of the equation
n + 4 -4 = 11-4
n = 7
Hey there!
n + 4 = 11
SUBTRACT 4 to BOTH SIDES
n + 4 - 4 = 11 - 4
CANCEL out: 4 - 4 because it give you 0
KEEP: 11 - 4 because it help solve for the n-value
NEW EQUATION: n = 11 - 4
SIMPLIFY IT!
n = 7
Therefore, your answer is: n = 7

What is the volume of this pyramid? 32 cm 9 cm 15 cm
Answer:
720cm^3
Step-by-step explanation:
The volume of the pyramid with a = 9cm, b = 15cm and l = 32cm is 720cm^3.
Answer:
720³ cm
The formula for volume is...
length ×width ×heightWith that information, we should multiply the smaller numbers first.

Replace the substituted parameters with 9 and 15, then multiply them and solve.[tex]B = \frac{1}{2}(9)(15) = \frac{135}{2}[/tex]
UseV for volume.[tex]V = \frac{1}{3} * \frac{135}{2} * 32 = 45 * 16[/tex]
