Answer:
Option B (1,10)
Step-by-step explanation:
we have
we know that
If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)
<u><em>Verify each case</em></u>
case A) (0,0)
For x=0
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
case B) (1,10)
For x=1
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is on the graph of f(x)
case C) (0,10)
For x=0
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
case D) (10,1)
For x=10
Compare the value of f(x) with the y-coordinate of the ordered pair
therefore
The ordered pair is not on the graph of f(x)
The value of a would be 3.5, as a=1 when b=10 means that a is worth 1/10 of b's value.
Alright, lets get started.
Suppose the original deck size: width = x feet
the width is one-fourth the length given in question means length = 4 x feet
Means the originally area =
Now the dimensions are changed.
New dimensions, width = (x + 6)
new length = (4x+10)
So, new area will be =
the area of the new rectangular deck is 128 ft2 larger than the area of the original deck, means
Subtracting from both sides
Subtracting 60 from both sides
Dividing 34 in both sides
Means width = 2 feet
Length would be = 4 time width = 4 * 2 = 8 feet
Means dimension of original deck would be = 2 feet and 8 feet :Answer
Hope it will help :)
Just plot the values onto a normal number line
I’m not exactly sure what you mean by “write it in math,” however I can tell you what I think.
4y=x
(It says that x is 4 times the value of y which means that y times 4 is x.)
