Answer:
-3a² - ab - 7ac - 2b² + 6bc + 4c²
Step-by-step explanation:
Step 1: Distribute
3a² + 3ab + 3ac - 2ab + 2b² -2bc
Step 2: Combine like terms
3a² + ab + 3ac + 2b² - 2bc
Step 3: Distribute again
-4ac + 4bc + 4c² - (3a² +ab + 3ac + 2b² -2bc)
Step 4: Combine like terms again
-3a² - ab - 7ac - 2b² + 6bc + 4c²
And you have your final answer.
Hello there! :)
Given:
x-coordinate of point = -2
y-coordinate of point = 5
Slope, or "m" = 1/5
Substitute in these values into slope-intercept formula (y = mx+b)
5 = 1/5(-2) + b
5 = -2/5 + b
25/5 = -2/5 + b
27/5 = b
Rewrite the equation:
y = 1/5x + 27/5
Graph the equation using a graphing utility:
Answer:
hmm... 65 or smwr near?
