Variables - a quantity that may change, depends on the context of the math problem.  Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc

Which bacteria sample (A or B) had a smaller initial population? What was that value?
zubka84 [21]

Answer:

B has a smaller initial population of 500

Step-by-step explanation:

Given

See attachment for complete question

Required

The bacteria with the smaller initial population

The initial population is at x = 0

For bacteria A;

A(x) = 600 when x = 0

For bacteria B, we have:

B(x) = 500(2)^x

Substitute 0 for x

B(x) = 500(2)^0

B(x) = 500*1

B(x) = 500

So; when x = 0

A(x) = 600 and B(x) = 500

Because; 500 < 600

We can conclude that B has a smaller initial population of 500

Answer:

Claimed statement is he worst is yet to come, with an earthquake 142,990 times  as intense as the 1906 earthquake ready to hit San Francisco.

We need to find the magnitude of their  claimed earthquake.

It can be calculated by simply multiplying 142,990 by 7.8 as follows :

E=142990 \times 7.8\\\\=1115322

The magnitude of claimed earthquake is 1115322 .

H : because each square contains 100 blocks so the two boxes would be 200 together and as you see one square has all blocks shaded ( 100% ) and then has another 100 block with only 40% shaded in 100% + 40% = 140%

Pepsi [2]

We can isolate y in the linear equation to get:

y = 4x - 8

<h3>How to isolate the variable?</h3>

Here we have the linear equation:

8x - 2y = 16

Now, remember that we can perform the same operation in both sides of the equation, and the equation don't changes.

To isolate y, we can start by subtracting 8x in both sides, so we get:

-2y = 16 - 8x

Now we should divide both sides by -2:

y = (16 - 8x)/(-2) = -8 + 4x

y = 4x - 8
