Answer:
<u>Linear</u>
y=-x
<u>Non linear</u>
Step-by-step explanation:
Linear equations have the highest degree to be 1.
Therefore y=-x is linear.
The degree of this equation is 2.
It is non-linear
is also linear.
Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for .
Based on given conditions,
Now collecting the coefficients and adding them,
Hence, the <u>6</u><u>a</u><u>²</u><u>b</u><u> </u><u>+</u><u> </u><u>1</u><u>2</u><u>a</u><u>b</u> should be added.
C is the correct answer choice
