Answer:15 and 7
Step-by-step explanation:
X-Y=8 ,2X+3Y=51 ,X=Y+8,2(Y+8)+3Y=51 ,5Y+16=51,5Y=35 ,Y=7 , X=7+8=15
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain
d(siny)/dz = dx/dz
(cosy)dy/dz = dx/dz
dy/dz = (1/cosy)dx/dz
