Answer:
As i multiplied the answer i got is
48x^3-4x^2+18x-40
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
Answer:
D 1.33
Step-by-step explanation:
B and C are less than 1
A is one and .30
D is one and .33
33>30
Answer:
f(x) = a+b/x
We = 0
So that f(x) = 3+7/x = f(x) = 3+7/-2 = 5 also 3+7/-2+2 = 10/0 = -1
Step-by-step explanation:
Answer: bacteria 2
Step-by-step explanation:
Since the growth rates are modeled as : Bacteria 1: y = 4x
And Bacteria 2: y = 4x2
Where y represents the number of bacteria colonies and x represents the number of hours.
Let's plug in for the two models
By assuming x = 2 and x = 3
If x = 2
Bacteria 1 will be y = 8 and bacteria 2 will be y = 16
Based on these models, bacteria 2 is growing faster than bacteria 1 because the growth is exponential
