Answer:
Step-by-step explanation:
Example of a linear function: y = -5x + 2. Note that both x and y are to the first power: y^1 and x^1.
Example of a nonlinear function: y = 2x^2 - x - 13. Here x is to the second power (which automatically makes this a nonlinear function).

Answer:
6. Because to decrease = number × 100-% over 100(as a fraction)
which is =39.99 ×100-30% over 100
= 39.99 × 70/100
=27.993
After you take your answer from the decrease and subtract from the original price which is 39.99
39.99-27.993 *note the 39.99 has a zero at the end
the answer = 11.997 Rounded off it becomes 12
I am not sure about this but here goes nothing: d=2.5t+2.2 is very familiar to y=mx+b y=d m=2.5 x=t b=2.2 to find a new quasion we substitute d and t into place wich equals 1=2.5(0)+b simplification and you get b=1 so your answer is d=2.5t+1
Answer:
y = -2x + 6
Step-by-step explanation:
y = -2x + b
-4 = -2(5) + b
-4 = -10 + b
6 = b
