So we say x=-2
so in the equation where ever we see x we plug in like
f(-2)= 2 * (-3)^3 + 3 * (-2)^2
= 2 * -8+ 3 * 4
= -4
(-2,-4)
hope that helps
Okay. So the keynote speaker has 1/4 of an hour to speak, which means that 1 1/4 hours or 75 minutes are left for speakers. To find out the amount of time for each of the remaining 5 speakers, you have to divide 75 by 5. 75/5=15. The remaining 5 speakers will have 15 minutes to give their speech.
We'll use Cramer's rule for 2 equations:
ax + by = e
cx + dy = f
5x -3y = 18 a=5 b=-3 e=18
2x + 7y = -1 c=2 d=7 f=-1
denominator determinant (dn) = (a * d) - (c * b) = 5 * 7 - (2 * -3) = 41
x = [(e * d) - (f * b)] / dn
[18 * 7 - (-1 * -3)] / 41 =
123 / 41 = 3
y = [(a * f) - (c * e)] / dn
= (5 * -1) -(2 * 18) / 41 =
-41 / 41 = -1
