Answer:
Step-by-step explanation:
<u>Proportional relationship is:</u>
- y = kx, where k is the constant of proportionality
We have a point (5, 2). it means x = 5, y = 2
<u>Substitute x and y and find k:</u>

Only one
Answer:
The value of the car in 8 years is : v(t)=69,326 rounded to the nearest dollar, yet if not rounded to the nearest dollar then it is 69,326.968936
Step-by-step explanation:
v(t)=28,000(1.12)^8
v(8)=69,326
Answer:
- Powers of the variable descending left to right
- right side of the equal sign is 0
Step-by-step explanation:
For some constants a, b, and c, the standard form* is ...
ax^2 + bx + c = 0
___
It is nice if the leading coefficient (a) is positive, but that is not required.
The main ideas are that ...
- Powers of the variable are descending
- All of the non-zero terms are on the left side of the equal sign
- Like terms are combined
_____
* This is the <em>standard form</em> for a quadratic. For other kinds of equations, when the expression is equal to zero, this would be called "general form."
