( -3,4 ) let me know if you need an extension
Answer:
Ok so T=time so a b and c would be 300 -10(a or b or c)
Step-by-step explanation:
Find the greatest common multiple of 12 and 8 is 4
To find a perpendicular line, you need to find the negative reciprocal of the slope.
-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.
Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
1 -since everything includes 4a, we can factor that to get 4a(a-4b^3+2b^2c)
2 - since 5 and 3 add to 8 and multiply to 15, we can do (n+5)(n+3)
3 - since -5 and -4 add to -9 and multiply to 20, we can do (g-5)(g-4)
4 - since -10 and 3 add to -7 and multiply to 30, we can do (z-10)(z+3)
5 - we can factor out 4y to get 4y(y^2-9).
I got the numbers in 2, 3, and 4 with a guesstimating and checking approach
