For this case we must simplify the following expression:
![6 (1 + 8n) = - 39 + 3n](https://tex.z-dn.net/?f=6%20%281%20%2B%208n%29%20%3D%20-%2039%20%2B%203n)
We apply distributive property on the left side of the equation:
![6 * 1 + 6 * 8n = -39 + 3n\\6 + 48n = -39 + 3n](https://tex.z-dn.net/?f=6%20%2A%201%20%2B%206%20%2A%208n%20%3D%20-39%20%2B%203n%5C%5C6%20%2B%2048n%20%3D%20-39%20%2B%203n)
We subtract 3n from both sides of the equation:
![6 + 48n-3n = -39\\6 + 45n = -39](https://tex.z-dn.net/?f=6%20%2B%2048n-3n%20%3D%20-39%5C%5C6%20%2B%2045n%20%3D%20-39)
We subtract 6 from both sides of the equation:
![45n = -39-6\\45n = -45](https://tex.z-dn.net/?f=45n%20%3D%20-39-6%5C%5C45n%20%3D%20-45)
We divide between 45 on both sides of the equation:
![n = \frac {-45} {45}\\n = -1](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%20%7B-45%7D%20%7B45%7D%5C%5Cn%20%3D%20-1)
Answer:
![n = -1](https://tex.z-dn.net/?f=n%20%3D%20-1)
Answer:
43
Step-by-step explanation:
180 - 43 = 137
then,
180 - 137 = 43
Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
Answer:
D.44
Step-by-step explanation:
i hope its help for you po
Wouldn’t you just for part a, insert different x values and solve to get your y value. and do that over and over again with different numbers to create a data table. and then for part b you’ll just make a graph and put down the points. so for the first slot, do 0 for x. y will equal -1 after solving, so your first plot for part b can be (0,-1) and continue on from there
