8a² - 4b + 7a² and 5(3a² - 2b) + 6

First, simplify the expressions.

1) 8a² - 4b + 7a²

Add like terms.

15a² - 4b

2) 5(3a² - 2b) + 6

Distribute 5 by multiplying the number to each terms inside the parenthesis.

15a² - 10b + 6

15a² - 4b ≠ 15a² - 10b + 6

Solution: The expressions are not equivalent.

A bacteria culture contains 100 cells and grows at a rate proportional to its size. After one hour the population has increased
xenn [34]
We know it begins at 100. If we use a*b^t, then 100 is our a. 100*b^t. We can now divide 480 by 100. This is 4.8. 4.8 is b. f(t) = 100(4.8)^t

When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88
Natali5045456 [20]
Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2. 

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 4x + 8y = 16 4x - 8y = 0 A. (4, 2)
balu736 [363]
Adding both equations cancels y:

<span>4x + 8y = 16 
</span><span>4x - 8y = 0 
-----------------+
8x = 16 => x=2

filling in x=2 in the first equation gives:

4*2 + 8y = 16 => 8y = 8 => y=1

So (2,1) is the (x,y) pair that solves the two equations. Answer C.</span>
