Answer:
Sorry but how am I supposed to know?
P(x) = x-4
k(x-4) = 5(x-4) - 8 = 5x - 28
So the answer is 2
Answer:
f>-9
Step-by-step explanation:
Answer:
(AD)=SQRT(20n^2+34-4n)
Step-by-step explanation:
let the point of intersection between AC and DB be O. Then the length of OA is the same as that of OC which is=2n+5
Similarly the length of DO is the same as that of OB which is=4n-3
Now from Pathagoras theorem we get
(AD)=SQRT((DO)^2+(OA)^2)
(AD)=SQRT((4N-3)^2+(2N+5)^2)
(AD)=SQRT((16n^2+9-24n)+(4n^2+25+20n))
(AD)=SQRT(20n^2+34-4n)
Y α x²
y = kx²
64 = k*4²
64 = k*4*4
64 = 16k
64/16 = k
4 = k
k = 4
y = kx²
y = 4*6²
y = 4*6*6
y = 144
