Answer:
B) y + 7 = 5x
Step-by-step explanation:
In math, a linear function is one that has a graph that is a line. It looks like this: There are two things that make up the equation: y = f(x) = a + bx. One independent variable and one dependent variable make up a linear function, which is also called a simple function. The independent variable is x, and the dependent variable is y, which is what you're interested in. Also, there are no exponents in a linear function, which means the exponent is one.
Answer:
B
Step-by-step explanation:
eliminating the y-term
(y + z = 6) × -5
99.7% encompasses about 3 standard deviations either side of the mean.
82 ±3*2 = (76, 88)
About 99.7% of the values lie between 76 and 88.
Initially = 80 pounds
It triples every 2 hours
2 hours later = 3(80)
4 hours later = 3(3(80)))
6 hours later = 3(3(3(80)))
8 hours later = 3(3(3(3(3(80)))))
8 hours later =

x 80
8 hours later =
6480 (Answer C)
OR
We find the number of 2 hours period in that 8 hours
8 ÷ 2 = 4
It starts at 80 pounds
It tripes every 2 hours
Total algae =

x 80 =
6480 (Answer C)
