Answer:
x < -2
Step-by-step explanation:
subtract 6 from each side
-3x > 6
divide both sides by -3
x < -2
(with inequalities you must flip the sign if you divide by a negative number)
Answer:
2 pieces (that each equal 1/3 of the whole bar)
Answer:
a): A line has a total degree of 180. So just subtract it. 180-92 is
y=88
b): Similar to the previous, a right angle has a total angle of 90. 90-45=45.
y=45.
These are all the ones I can figure out. I hope someone else can get c) and d).

Step-by-step explanation:
The equation that describes the number of bacteria in both the foods when they are mixed is; Option C: 35T₂ + 55T + 450
<h3>How to simply quadratic Equations?</h3>
We are given the equations that describes the number of bacteria in both the foods when they are mixed.
Equation for first bacteria is;
N₁(T) = 15T₂ + 60T + 300
Equation for second Bacteria is;
N₂(T) = 20T² - 5T + 150
The equation that describes the number of bacteria in both the foods when they are mixed is;
N₁(T) + N₂(T) = 15T₂ + 60T + 300 + 20T² - 5T + 150
⇒ 35T₂ + 55T + 450
