-4x = y + 3
y = -4x - 3

The second equation is solved for y.
We'll leave it like that.
Now we solve the first equation for y.

-4x = y + 3

-4x - 3 = y

y = -4x - 3

Write the new form of the first equation followed by the original second equation.

y = -4x - 3
y = -4x - 3

Before we get to the addition method, we see that both equations are the same.

The solution is every real number.

4. Suppose that Peculiar Purples and Outrageous Oranges are two different and unusual types of bacteria. Both types multiply thr
Viktor [21]

Answer:

Peculiar purples would be more abundant

Step-by-step explanation:

Given that eculiar Purples and Outrageous Oranges are two different and unusual types of bacteria. Both types multiply through a mechanism in which each single  bacterial cell splits into four. Time taken for one split is 12 m for I one and 10 minutes for 2nd

The function representing would be

i) P=P_0 (4)^{t/12} for I bacteria where t is no of minutes from start.

ii) P=P_0 (4)^{t/10} for II bacteria where t is no of minutes from start. P0 is the initial count of bacteria.

a) Here P0 =3, time t = 60 minutes.

i) I bacteria P = 3(4)^{5} =3072

ii) II bacteria P = 3(4)^{4} =768

b) Since II is multiplying more we find that I type will be more abundant.

The difference in two hours would be

3(4)^{10}- 3(4)^{8} =2949120

c) i) P=P_0 (4)^{t/12} for I bacteria where t is no of minutes from start.

ii) P=P_0 (4)^{t/10} for II bacteria where t is no of minutes from start. P0 is the initial count of bacteria.

d) At time 36 minutes we have t = 36

Peculiar purples would be

i) P=3 (4)^{36/12}=192

The rate may not be constant for a longer time.  Hence this may not be accurate.

e) when splits into 2, we get

P=P_o (2^t) where P0 is initial and t = interval of time

You know that 44% of a number x is 99 you also know that 22% of a number y is 55 what are the values of x and y which number is
Tomtit [17]
44% of a number x is 99
44%=0.44
0.44×99= 43.56


22% of a number y is 55
22%=0.22
0.22×55=12.1



the greater number is 44% of a number is 99 so the value is 43.56

Which is a reasonable domain for the function f(x)=10x+8
Soloha48 [4]

Answer:

(-∞,∞)

Step-by-step explanation:

The domain is all possible x values of the function

There are no constraints or holes for this and therefore the domain is all real numbers

How do you solve this don’t mind the (f) that’s just the problem number
zavuch27 [327]
Hello,
You need to evaluate the equation, so:
3xˆ2+14x+8 --> 17xˆ2+8. Hop this helps!
