Answer:
A
(1,5),(2,6),(4,5)
Step-by-step explanation:
Think of the answer choice in a table
x | y
1 | 5
2 | 6
4 | 5
exactly one input (x) has one output (y)
in a function likw this you have to make sure that the x is going to one y.
if not than it is not a function.
(1,2),(1,5)(3,9)
see the one in this orderd pair goes to 2 and 5 so in is not a function
Answer: 12x^3 + 19x^2 -27x -40
Step-by-step explanation:
Finding f(x) times g(x) is multiply the two polynomials
(4x+5)(3x^2 + 1x -8) Apply the distributive property twice to solve
4x ( 3x^2 + 1x -8)
12x^3 + 4x^2 - 32x
5(3x^2 + 1x -8)
15x^2 + 5x - 40
12x^3 + 4x^2 - 32x + 15x^2 + 5x -40 now combine like terms
12x^3 + 19x^2 -27x -40
can I see the full question but if the question asks how many liters in total add
1.25 + 2.5 + 1 = 4.75 L
Answer:
15
Step-by-step explanation:
Given that the profit equation from selling x necklaces is
P = −x2 + 35x.
To make a profit of $300, the profit P = 300 then
300 = -x2 + 35x
x2 - 35x + 300 = 0
solve by factorization
x2 - 15x - 20x + 300 = 0
x(x - 15) - 20(x - 15) = 0
(x - 15)(x - 20) = 0
x - 15 = 0 or x - 20 = 0
x = 15 or 20
Since 20 is higher, the least number of her necklaces she must sell to make a profit of $300.00 is 15
