Table 1 and table 3 are represent linear functions of x.
What is a linear function?A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra.
Given are four tables, we need to find that which of them shows linear functions of x,
Linear functions will have the ratios of x and y coordinates, constant.
In table 1 :-
x/y = -1/2
-2/4 = -1/2
-3/6 = -1/2
Since the x and y coordinates are constant, therefore, the function is linear.
In table 2 :-
x/y = 1/1 = 1
2/4 = 1/2
3/9 = 1/3
Since the x and y coordinates are not constant, therefore, the function is not linear.
In table 3 :-
x/y = 1/5
2/10 = 1/5
3/15 = 1/5
Since the x and y coordinates are constant, therefore, the function is linear.
In table 4 :-
x/y = 1/1 = 1
2/8 = 1/4
3/27 = 1/9
Since the x and y coordinates are not constant, therefore, the function is not linear.
Hence, table 1 and table 3 are represent linear functions of x.

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2
Equations
l^2 + r^2 = l^2
l is the slant height.
Solution
SA = π * l * r + π r² = π(1 + √5) Divide both sides by π
Find l
l * r + r^2 = 1 + √5
l^2 = r^2 + h^2
l^2 = r^2 + (2r)^2
l^2 = 5r^2
l = √5 * r
Now go back to this equation to find r
l * r + r^2 = 1 + √5 Substitute the value for l
√5 r * r + r^2 = 1 + √5 On the left pull out r^2
r^2 (1 + √5) = 1 + √5 Divide by 1 + √5
r^2 = 1 Take the square root on both sides
sqrt(r^2) = sqrt(1)
r =1
Therefore h = 2
Volume of the cone.
V = 1/3 * π r² h

Answer:
The answer is ;
9x/2y^2
Step-by-step explanation:
Here, we want to simplify as far as possible
Let us take all the numbers one after the other
All numbers on numerator and denominator;
(4 * 9)/(2 * 4) = 9/2
All x
(x^2 * x^2)/(x^2 * x) = x
All y
(y^4 * y^4)/(y * y^9) = y^8/y^10 = 1/y^2
So the complete answer is;
9/2 * x * 1/y^2
= 9x/2y^2

A seed company planted a floral mosaic of a national flag. The perimeter of the
rectangular planting area is 420 feet. The length of the area is 110 feet longer
than the width.
a.) Write a system of equations to relate the
length and width of the planting area.
b.) Use the system of equations to
determine the length and width of
the planting area.
9514 1404 393
Answer:
a) 2(L+W)=420; L-W=110
b) length: 160 ft; width: 50 ft
Step-by-step explanation:
The formula for the perimeter (P) in terms of length (L) and width (W) is ...
P = 2(L+W)
We can use this as one of the equations. The other will relate the length and width according to their difference:
L -110 = W
Substituting the given perimeter in the above equation, our system of equations is ...
420 = 2(L+W)L-110 = WSubstituting for W in the first equation gives ...
420 = 2(L +(L -110))
210 = 2L -110
320 = 2L
160 = L
160 -110 = W = 50
The planting area is 160 feet long by 50 feet wide.

Comment on the question
Most national flags have a length/width ratio of 1.5 or 2. The flags of Vatican City and Switzerland are square (1.0). The longest flag is that of Qatar, with an aspect ratio of width:length = 11:28, about 2.545. The "national flag" described here has an aspect ratio of width:length = 5:16, or 3.2. Apparently, it is not to scale, or not from Earth. (The US flag aspect ratio is 1.9.)

A car driving cross-country traveled 180 mites in 4 hours. At this rate of speed, how many mites further will the car travel in the next 3 hours?
Answer:
I'm sure you mean miles, but the car will travel 135 mites.
Step-by-step explanation:
(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

What is the value of x?
What is the measure of
Answer:
x is 10
Step-by-step explanation:
Form the diagram, you can see that UV is parallel to TS, this means that <UVS = < UTS
Given
<UVS = 5x + 38
<UTS = 12x - 28
Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;
5x + 38 + 12x - 28 = 180
Collect like terms
5x + 12x - 28 + 38 = 180
17x + 10 = 180
17x = 180-1-
17x = 170
x = 170/17
x = 10
hence the value of x is 10

All of the following represent the same function except _____.
y = x - 1
{(0, 1), (2, 3), (4, 5), (7, 8)}
x y
1 0
3 2
5 4
8 7
Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}
Step-by-step explanation:
For the function: y = x - 1 (y is one less than x)
If x =1 , y= 0
if x= 3 . y= 2
If x = 5 , y= 4
If x= 8 , y= 7
So it is same as
x y
1 0
3 2
5 4
8 7
But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]
So, the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .
