Answer: x=5, y=-5, z=6
Step-by-step explanation:
x+y+z=6 -> 2x+2y+2z=12
subtract 2x+4y+2z=2 from this, and you get -2y=10 -> y=-5
So, x+z=11 and -x-3z=-23
x+z=11
-x-3z=23
---------
-2z=-12
z=-6
Meaning x=5.
3x - 4 = 18+5x
-3x -3x
-4-18 = 18 + 2x
-18
-22 = 2x
2x/2 = -22/2
x= -22/2
x= -11
Final answer: x = -11
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let p represent the bacteria population in thousand after d days.
Since each day, the bacteria population grows by a factor of 2, hence:
Hence, d = log₂p represents a logarithmic function
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Answer: Linear
Step-by-step explanation:
It wouldn't be exponential because there isn't exponent, and it won't be rational because there is no fraction, and it is not quadratic. Hope this helps :)
Answer:
4y + 5 = 2
Step-by-step explanation:
4y + 5 = 2 Subtract 5 from both sides
4y = -3 Divide both sides by 4
y =
