Answer:
y=3x - Linear Function
y=4x-1 - Linear Function
y=x²+1 - Non-Linear Function
y=0.75x+2 - Linear Function
y=0.5x³ - Non-Linear Function
(For a function to be linear, both x & y must equal 1.)
Answer: b ≤ -18
<u>Step-by-step explanation:</u>
Isolate the variable by multiplying both sides by -3. Remember that when you multiply or divide by a negativem the symbol flips.
Difference of two squares:
(a+b)(a-b) = a² - b²
(a-b)(a+b) = a² - b²
The difference of two squares results to a binomial because the middle term cancels each other out.
example:
a = 2 ; b = 3
(2 - 3)(2 + 3) = 2(2+3)-3(2+3) = 4+6-6+9 = 4 + 0 + 9 = 4 + 9
