Answer: If you think of the relationship between two quantities, you can think of this relationship in terms of an input/output machine. If there is only one output for every input, you have a function. If not, you have a relation. You can conclude that this set of ordered pairs does not represent a function

Answer:
$659.25
Step-by-step explanation:
Since its 25 percent off we need to see what it would look as a decimal
1-.25=.75
879times.75= 659.25
-3x - 4y = 2
<u>8y</u> = <u>-6x - 4</u>
8 8
y = -0.75x - 0.5
-3x - 4(-0.75x - 0.5) = 2
-3x + 3x + 2 = 2
0x + 2 = 2
<u> - 2 - 2</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-3(0) - 4y = 2
0 - 4y = 2
<u>- 0 - 0</u>
<u>-4y</u> = <u>2</u>
-4 -4
y = 0.5
(x, y) = (0, 0.5)
Answer:
$600
Step-by-step explanation:
Simple Interest Rate: A = P(1 + RT)
A 
Total Value
P Principle
R Rate
T Time
__________________________________________________________
<h2>Step 1: Insert Values </h2><h2> </h2>
Let's plug the info we have into the formula:
A = 4000(1 + 0.05(3))
A = 4000 + 4000(0.15)
A = 4000 + 600
A = 4600
__________________________________________________________
<h2>Step 2: Finding the Interest</h2><h2 />
So the total value she ends up with $4600, but we want to find the extra value, or interest, she has to pay.
To find this we subtract the principle from the new value:
4600 - 4000 = 600
Liz has to pay $600.

Step-by-step explanation:
Length of rectangle is 140 m and its breadth is 100 m
Perimeter = sum of all sides
For rectangle, P = 2(l+b)
P = 2(140+100)
P = 480 m
Area = length × breadth
For a rectangle, A = lb
A = 140 × 100
A = 14000 m²
We need to write the length and breadth such that it has the same perimeter but a larger area.
Let the length is 110 m and breadth is 130 m.
Perimeter, P = 2(110+130)
P = 480 m
Perimeter is same as previous
Area, A = 110 × 130
A = 14300 m²
Area is more than the initial area.
Hence, this is the required solution.
