Answer:
y= -2/3x+8/3
Step-by-step explanation:
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
30x-15
Step-by-step explanation:
Answer(s):
- Dependent variable: v
- Independent variable: t
What is the dependent variable of an equation?
The dependent variable of an equation is the variable that is completely isolated on one side.
What is the independent variable of an equation?
The independent variable is the variable that is not isolated. The independent variable can either have a cooeficient or has some operation (+ - × ÷) included on that side of the equation.
Determining the independent and dependent variable
In this equation, we can see that "v" is completely isolated on one side and "t" has a cooeficient of 68. Thus, the dependent variable is "v" and the independent variable is "t".
