Answer:
Like I said from before, just make sire all the X’s are different for a function
DOn’t worry about the y, if there are repeating Ys, it doesn’t matter
If the each X is different from other Xs then its a function, if there are more then 1 x it’s not a function.
In This case the answer is
D or the last option
(1,-1),(-3,-8),(8,-1),(0,5)
Step-by-step explanation:
(-3,1),(8,-2),(0,0),(8,6) is not a function
(-1,-8),(-8,-3),(-8,7),(4,1) is not a function
(-3,-8),(-3,-7),(2,-7),(6,-4) is not a function
(1,-1),(-3,-8),(8,-1),(0,5) has to be the function
18x^2+6
2(9x^2+3)
multiply each term in parentheses by 2
2 x 9x^2+2 x 3
calculate product
18x^2+2 x 3
multiply numbers
Shipping box is a cube, with units
Fish food is an unitary cube, that means have x,y,z measures the same
Shipping box is a parallelepip box. Rectangular
Volume of shipping box is found by formula
V = X•Y•Z
X = 3ft, Y=3 3/4 ft, Z=3 1/4 ft
then V = (3•3+ 3•3/4)•(3+1/4) = (11 +1/4)• (3+1/4) = 33 + 11/4 + 3/4 + 1/16
V = 33 + 2 + 3/4+ 3/4 +1/16 = 35 + 25/16 = 34+ 9/16
Now, find volume using packing cubes
How many fish food boxes fit
In X direction it fits 3/(1/4) = 12
In Y direction it fits (3+3/4)/(1/4)= 15
In Z direction it fits (3+1/4)/(1/4) = 10
Now then multiply 12x15x10= 1800 fish boxes fit in larger box
