Step-by-step explanation:
x + y = 16 (*)
x^2 + y^2 = 146 (**)
(*) <=> x= 16-y
substitute x = 16 - y
(**) <=> (16-y)^2 + y^2 = 146
<=> y^2 - 2.16.y + 16^2 + y^2 = 146
<=> 2y^2 - 32y + 110 = 0
<=> y^2 - 16y + 55 = 0
<=> (y-11)(y-5) = 0
<=> y=11 or y= 5
For y = 11, we have x= 16-11=5
For y=5, we have x= 16-5=11
Answer: (x,y) = (11,5) ; (5,11)
Answer:
Part A: 18x^2+63x+55, B: second degree trinomial, Part c: (3x+5) (6x+11) =18x^2+63x+55
I don’t really know I’m guessing Sorry A 4
Number of strawberry = 1
Number of Lime = 1
Number of Lemon = 1
Number of Cherry = 1
Number of Blueberry = 1
Total number of candies = 1 +1 + 1 +1 +1 +1 =6
favourable outcome = 1
P(of selecting blueberry ) = 
P(of selecting blueberry) = 
P(of selecting blueberry) = 0.1666
P(of selecting blueberry) = 0.17
Answer:
9
Step-by-step explanation:
Because the Y's cancel out you add the absolute value of negative 5 and 4.
