Answer: I’m pretty sure its D) 1 1/9
Answer:
1. -6
Step-by-step explanation:
f(x)=x²-9
g(x)= x-3
1. (f+g)(2) =
(2²-9)+(2-3) = (4-9)+(2-3) = (-5)+(-1)= -6
Answer:
it would be -18
Step-by-step explanation:
because you would divide 108 by 6 and you will get -18 each second

Answer: 5 - 4i (choice A)</h3>
===================================================
Work Shown:
x = the other number
(5+4i)*x = 41
x = 41/(5+4i)
x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below
x = 41*(5-4i)/( 41 )
x = (41/41)*(5-4i)
x = 5 - 4i
As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41
The rule used is (a-bi)(a+bi) = a^2 + b^2
-----------
Note: I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.
Christina can buy 7 bananas because one papaya is 8 dollars and then you do 50-8=42 and then 42/6 which equals 7.
Billy can only buy one pair of jeans. The reason is that jeans are 35 bucks and he has already spent 55 dollars on a hat and jacket and that leaves him with 35 bucks left so 35-35 equals zero!
