Answer:
A
Explanation:
Not every single point is on line A, but just by eyeballing the other 3, you can see that line A is much closer to the distribution of points than any of the others.
Hope this helps!
Answer:
![[\frac{16}{21}, 1\frac{17}{21}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B16%7D%7B21%7D%2C%201%5Cfrac%7B17%7D%7B21%7D%5D)
Step-by-step explanation:
{y = 5x - 2
{x + 4y = 8
Use the Substitution Method:
x + 4[5x - 2] = 8
x + 20x - 8 = 8
21x - 8 = 8
+ 8 + 8
__________
21x = 16
____ __
21 21
x = 16⁄21 [Plug this back into both equations above to get the y-coordinate of 1 17⁄21]; 1 17⁄21 = y

Answer:
![\boxed{\sf D)\:-24a^3b^7}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20D%29%5C%3A-24a%5E3b%5E7%7D)
Step-by-step explanation:
![\sf (3a^2b^4)(-8ab^3)](https://tex.z-dn.net/?f=%5Csf%20%283a%5E2b%5E4%29%28-8ab%5E3%29)
We'll use rule of exponents to simplify expression.
![\sf 3^1a^2b^4(-8)^1a^1b^3](https://tex.z-dn.net/?f=%5Csf%203%5E1a%5E2b%5E4%28-8%29%5E1a%5E1b%5E3)
Now, use the commutative property of multiplication.
![\sf 3^1(-8)^1a^2a^2b^4b^4](https://tex.z-dn.net/?f=%5Csf%203%5E1%28-8%29%5E1a%5E2a%5E2b%5E4b%5E4)
In order to multiply power of the same base, we add their exponents.
![\sf 3^2(-8)^1a^{2+1}b^{4+3}](https://tex.z-dn.net/?f=%5Csf%203%5E2%28-8%29%5E1a%5E%7B2%2B1%7Db%5E%7B4%2B3%7D)
→ Add exponents:
![\sf 3^1(-8)^1a^3b^7](https://tex.z-dn.net/?f=%5Csf%203%5E1%28-8%29%5E1a%5E3b%5E7)
→ Multiply 3* -8
![\sf -24a^3b^7](https://tex.z-dn.net/?f=%5Csf%20-24a%5E3b%5E7)
