Given system of equation:
y=-1/5x +1 Equation 1
y=x+4 Equation 2
Substitute value of y in equation 2.
x+4=-1/5x+1
Multiply both sides by 5.
5x+20=-x+5
Add x to both sides
6x+20=5
Subtract 20 from both sides
6x=-15
x=-15/6
x=-5/2
Now substitute value of x in equation 1.
y=-1/5 ( -5/2) +1
y=1/2+1
y=3/2
Solution is (x,y)= (-5/2 , 3/2)
via the angle sum formula of sin
which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true

Answer:
Step-by-step explanation:
Notice that each new term is closer to +1 than was the previous term. We can conclude tat the sequence converges to 1.
Answer:
mean =503.75
median=400
mode=400
range=691
Step-by-step explanation:
mean= 211+351+359+400+400+659+748+902=4030/8= 503.75
range= highest number -lowest number = 902-211=691
median= 400+400 =800/2= 400
