What is the answer to 16a5 b3/8ab ?
marishachu [46]

Answer:

When we are dividing exponents, there is this rule:

\frac{a^n}{a^m}=a^{(n-m)}

So, in our case we have this:

\frac{16a^5b^3}{8ab} = \frac{16}{8}a^{(5-1)}b^{(3-1)}=2a^4b^2

Svet_ta [14]

Answer: 3rd option

Step-by-step explanation: The answer would be the third option. Let's go through each one and explain why it's correct or incorrect. First of all, our function is y = x - 3 so we can plug numbers into our X and Y. If we follow the function y = x - 3, we have 8 = 10 - 3 which is incorrect for the first one so that can't be it. For the nest one, we have 13 = 10 - 3 which also does not make sense. For the third one, we have 7 = 10 - 3 which is correct. And the last one, we have 3 = 10 - 2 which is wrong. Therefore, the third option is the answer.

What is an equation of the line that passes through the points (2, -6)(2,−6) and (-1, 6)(−1,6)?
Crank

Answer:

y = -4x + 2

Step-by-step explanation:

To figure out the slope, plug the coordinates in the formula.

y2 - y1 / x2 - x1

= 6 - (-6) / -1 -2

= -4

Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b

y = -4x + b

-6 = -4(2) +b

-6 = -8 + b

2 = b
