(f+g)(x)=f(x)+g(x)
(f+g)(x)=3x+4+8x+1
(f+g)(x)=11x+5
(f+g)(0)=11(0)+5
(f+g)(0)=0+5
(f+g)(0)=5
Answer:
The Answers are

Step-by-step explanation:
Let we Know some Identities
cosec (-θ) = - cosec (θ)
sec (-θ) = sec (θ)
cot (-θ) = - cot (θ)
Also,

Therefore,

Answer:
90.8 m
Step-by-step explanation:
Pythagorean Theorem
A²+B²=C²
slant height = C
A = 19.6/2=9.8m
90.9 in to m = 2.3m
9.8²+B²=2.3²
B²=90.9²-2.3² = 8257.52
B=
= 90.8
First one is -3
Second one is 1
Answer:
x = 5 and y = 1 or (5, 1)
Step-by-step explanation:
2x -3y=7
3x-2y=13
Multiply (1st) equation by 3 and (2nd) equation by 2
6x -9y=21
6x-4y=26
----------------subtract
-5y = - 5
y = 1
Substitute y = 1 into 2x -3y=7
2x -3(1)=7
2x - 3 = 7
2x = 10
x = 5
Answer
x = 5 and y = 1 or (5, 1)
