I don't get this. (write a linear function f with the given values)
Answer:
f(x) = (1/2)x
Step-by-step explanation:
f(x) = mx + b
m is the slope
b is the y-intercept
m = rise/run
for every run of 2 in x
f(x) rises 1
m = 1/2
The y-intercept occurs when x = 0
from the table f(0) = 0
b = 0
Therefor
f(x) = (1/2)x + 0
f(x) = (1/2)x
Answer:
[tex]f(x) = 1/2*x[/tex]
Step-by-step explanation:
Linear functions are functions of the form "f(x) = a * x + b" where 'a' and 'b' are constants (numbers) and x is the input.
In this problem, you are given the inputs and outputs of the function. Since you know it is linear, you begin thinking about what number you can multiply on the left to get the value on the right.
-4 / 2 = -2
-2 / 2 = -1
0 / 2 = 0
We find that dividing x by 2 gives the correct output. Dividing by 2 is the same as multiplying by 1/2. Therefore, we have found the answer!
f(x) = 1/2 * x

Answer:
Zoila bought a rectangular rug. The rug is 8 feet long by 5 feet wide. What is the area of the rug?
Final Answer: The area of the rug is 1.6[tex]ft^{2}[/tex] .
Step-by-step explanation:
What is Ask? - What is the area of the rug?
Given - 8 feet long by 5 feet wide
Operation - Divide
Solution:
You can use Partial quotient or Algorithm or Box method dividing any number.
5 ÷ 8 = 1.3
But why 1.6?
Because it is the decimal form of it and it is an improper fraction.
[tex]\frac{8}{5}[/tex] OR 1.6 OR [tex]1\frac{3}{5}[/tex]Final Answer: 1.6 [tex]ft^{2}[/tex] is the area of the rug.

Select all the pairs of points so that the line between those points has slope 2/3.
B, (0,0)(3,2)
C, (1,5)(4,7)
D, (-2,-2)(4,2)
All of these ordered pairs have a slope of 2/3, by way of the slope formula.
The slope of option B, C and D are equal to 2/3.
The given slope is 2/3.
What is slope of a 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 formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
A) Using (0, 0) and (2, 3) we get slope as
Now, slope = (3-0)/(0-2)
=3/2
B) Using (0, 0) and (3, 2) we get slope as
Slope = (2-0)/(0-3)
= 2/3
C) Using (1, 5) and (4, 7) we get slope as
Slope = (7-5)/(4-1)
= 2/3
D) Using (-2, -2) and (4, 2) we get slope as
Slope =(2-(2))/(4-(-2))
= 4/6
= 2/3
E) Using (20, 30) and (-20, -30) we get slope as
Slope =(-30-30)/(-20-20)
= -60/(-40)
= 3/2
Therefore, the slope of option B, C and D are equal to 2/3.

Step-by-step explanation:
54 + 4(3/4 − 1/2)2
=> 54 + 4(1/4)2
=> 54 + (1)2
=> 54 + 2
=> 56
Therefore, 56 is our answer.

Frank practised for 4 hours and 35 minutes. If he stopped practising at 9:17 p.m, what time did he start practising?
4:42 p.m
You start with 9:17 and you subtract 4 hours. That gives you 5:17. Now you have to subtract the remaining 35 minutes. To make things easy we can make 5:17, five o-clock. We can do this by subtracting 17 then you'll get five o-clock. Now you have another 28 minutes to subtract. 5:00 - 28 = 4:42. Then you add the p.m.

Step-by-step explanation:
the gradient describes the slope or steepness of the line joining two points.
it is expressed as the ratio of
y coordinate change / x coordinate change
so, we need to find 2 good points (typical with integer coordinates) per line to see how y and x changes between them.
for A I see e.g. (1, 1) and (2, 4)
for B I see e.g. (0, 5) and (1, 1)
so, for A
x changes by +1 (from 1 to 2)
y changes by +3 (from 1 to 4)
the slope or gradient of A : 3/1 = 3
and for B
x changes by +1 (from 0 to 1)
y changes by -4 (from 5 to 1)
the slope or gradient of B : -4/1 = -4

In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.
any vertical line in the plane can intersect the graph of a function at most once.
HOW TO DO THIS
take your pencil and place it on your paper vertically (up and down direction)
move the pencil across the paper to the right
if the pencil crosses more than two points on the line it is not a function
the first problem would be a function
the second problem would be a function
the third problem would not be a function
