Which equation represent y as a linear function of x? A x= 5 B y=2x C y=2x^2 D y=x^3
1 answer:
We know that
The variable x must be either degree zero or degree 1 and the variable y must be 1st degree in order to be a linear function.
case A) x=5
the variable x is first degree but variable y is zero degree---> is not a linear function
case B) y=2x
the variable x is first degree and variable y is first degree----------> is a linear function
case C) y=2x²
the variable x is second degree and variable y is first degree----------> is not a linear function
case D) y=x³
the variable x is third degree and variable y is first degree----------> is not a linear function
the answer is
the option B) y=2x is a linear function

x = 180
Answer:
It can be solved in many forms
one by replacing each point to see which one satisfy the equation or by using quadratic formula
so the right answer is the fourth one
Answer:
140
Step-by-step explanation:
70% 200
---------- * ---------- = 70*2 = 140
100% 1
you cross out the 2 zeros from the 100% so it will be one then croos out the 2 zeros from 200 and you will have 70 * 2 and you will get 140
