Answer:

9 and -4

Step-by-step explanation:

Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

First, test if they multiply to -36:

9(-4)

= -36

Then, check if they add up to 5:

9 + (-4)

= 5

So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

Answer:

A) 1600 bacteria

B) 12800 bacteria

Step-by-step explanation:

We are told that the bacteria doubles every 4 hours.

Now, if the amount of bacteria is X, it means that for 4 hours, it becomes 2X and after 8 hours it becomes 2(2X)

For 12 hours, it becomes; 2 × (2(2X))

This means that for 12 hours, it becomes 2 × (2(2X)) = 8X

A) Since the lab starts with 200 bacteria, after 12 hours, it has;

N_12 = 8 × 200.

N_12 = 1600 bacteria

B) From above, we have seen that after t hours, where t is a multiple of 4, the number of bacteria is;

N_t = [2^(¼t - 1)] × (2X)

Where X is initial amount of bacteria.

Thus, after a day which is 24 hours, we have;

N_24 = 2^(¼(24) - 1) × 2X

N_24 = 2^(5) × 2X

Where X is 200, N_24 = 32 × 2(200) = 12800 bacteria

Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.

To calculate the new interest rate after purchasing points, we need to know the cost of one point and the number of points purchased.

One point typically costs 1% of the mortgage amount, so three points would cost 3% of the mortgage amount. The cost of the points is usually paid upfront at closing.

Assuming Neil's mortgage amount is $100,000, the cost of 3 points would be:

3% x $100,000 = $3,000

To calculate the new interest rate, we need to add the cost of the points to the original interest rate and then recalculate it as a percentage:

New rate = Original rate + (Cost of points / Mortgage amount)

New rate = 4.95% + ($3,000 / $100,000)

New rate = 4.95% + 3%

New rate = 7.95%

So, Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.

Answer:1144.2 for question 5

Step-by-step explanation:

Answer:

Option B, -10000

Step-by-step explanation:

Step 1:  Find the number that would be valid

As the x value gets closer to -1, the y values go to positive and negative infinity.  Therefore, the best value out of the options given would be -10,000 since it is the closest to negative infinity.

Answer:  Option B, -10000

Answer:

36.75 and 1/6 ( 6 accounts equally distributed )

Step-by-step explanation:

Number of Red counters to be sketched = 9

Number of Yellow counters = 4

The number of Zero pairs that can be made = 36.75

When you remove the Zero pairs the number of counters you would have = 6 accounts ie. 1/6

Answer:

5.02

Step-by-step explanation:

Answer:

Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.

That probably isn't a good answer, here's what I found on google:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Step-by-step explanation:

I'll do #10 as an example:

(x-5)y

distribute the numbers-  y(x)-y(5)

without the parentheses-  yx-y5

you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.

Here's #11:

-4(2a-3b+c)

distribute the numbers-  (-4*2a)-(-4*3b)+(-4c)

solve-  -4*2= -8

-4*3= -12

-8a-(-12)b+4c

*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing

Hope this helps you.
