Answer:
A. {(-5, 3) (6, 3) (1, 3) (2, 3)}
Step-by-step explanation:
The relation with no duplicate "x" values is also a function.
B: x=2 appears twice
C: x=3 appears 4 times
D: x=0 appears twice
Answer:
huh? -1 is a decimal number maybe write it as -1.0 ?
Answer:
T=12500-0.25y
Step-by-step explanation:
Step one:
given data
The value of the car is $12500.
let the value of the previous year be T
let the number of years be y
25% will be 0.25----this is equivalent to the gradient
The expression for the change in price can be represented linearly using the equation of a straight line,
y=mx+c
but since the price is reducing the expression becomes
y=-mx+c
Now, in this situation the expression for the cost after y years is
T=-(0.25y)+12500
rearrange
T=12500-0.25y
<u>The expression is T=12500-0.25y</u>

Answer: 80.94 square cm</h3>
==================================================
Work Shown:
Area of parallelogram = base*height
Area of parallelogram = 11.4*7.1
Area of parallelogram = 80.94 square cm
-------------
notes:
- The base and height always form a 90 degree angle (as shown by the small square marker).
- The side length of 8.9 cm is never used.
- We can write "square cm" as "cm^2" or
