Answer:
-2, -6
Step-by-step explanation:
using cramer rule
5 -3
-2 -1
calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11
using cramer rule
to calculate x we change the coefficient of x with the answer (8,10)
8 -3
10 -1
we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22
to calculate x
22/-11= -2
to calculate y we change the coefficient of y with the answer (8,10)
5 8
-2 10
we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66
to calculate y
66/-11= -6
Step-by-step explanation:
Since they have a common denominator the answer is (-5 + 2) / 6 = -3 / 6 = -1/2.
11.5 x 3.2 = 36.8m
-36.8 meters change in elevation
Sam is a little fish. He lives in the sea. He is very lonely. He wants to have a friend. The friend looks like him. Sam sees an ink fish. The ink fish has eight legs. He doesn't look like Sam. So Sam goes away. Sam meets a shark. He wants to say hello to the shark. The shark opens his big mouth. Sam runs away quickly. Sam is tired and hungry. He wants to have a rest. Then he sees a round fish. She says to him. "Hello! Would you like to be my friend?" Sam answers: "Of course! But you are round. I am flat." The round fish days: "But we are both fishes."
Sam thinks and says, "You are right. Let's be friends." They become good friends.
Answer:
Step-by-step explanation:
if x= -2
and P(x)=x^4+4x^3+6x^2-8
then P(-2)=(-2)^4+4*(-2)^3+6*(-2)^2-8=16-32+24-8=0
so P(x)=(x+2)* Q(x) and P(x) is divisible by x+2
