Answer:
y=log_2 (x)
Step-by-step explanation:
We see that the graph passes though the point (2,1). So we can write:
log_a (2) = 1 => a = 2
So it's a log in base 2.
Answer:
30 pounds of hard candy and 30 pouonds of soft candy
Step-by-step explanation:
$2 per pound added with $4 per pound would become $3 per pound
x pounds plus 60 - x pounds will add up to 60 pounds
(multiply the top with the bottom)
2x + 4x = 3(60)
6x = 180
x = 30
60 - 30 = 30
Answer:
d = 100t
Step-by-step explanation:
(x+3)(5x-4)(2x-1)
multiply the first two by foil method
F x × 5x =5x²
O -4 × x =-4x
I 3 x 5x =15x
L 3 × -4 =-12
(5x²+11x-12)(2x-1) distribute
2x(5x²+11x-12)=10x³+22x²-24x
-1(5x²+11x-12)=-5x²-11x+12
combine like terms
10x³+22x²-5x²-24x-11x+12
Answer: 10x³+17x²-35x+12
