Mathematics

Step-by-step explanation:

Point of intersections of the graph with x-axis are not clear.

Let these points are x = -a, -b and c

Therefore, function representing the graph will be,

f(x) = p(x + a)(x + b)(x - c)

Since, this graph crosses y-axis at (0, -6),

f(0) = p(0 + a)(0 + b)(0 - c) = -6

-pabc = -6

p = $\frac{6}{abc}$

Therefore, equation of the given function will be,

f(x) = $\frac{6}{abc}(x+a)(x+b)(x-c)$

Mathematics

the answer is the option D

boxes

Step-by-step explanation:

Let

x-----> the number of the oz boxes

y-----> the number of the oz boxes

we know that

x+y=24

y=24-x -----> equation A

3.5x+5y=97.5 -----> equation B

Substitute equation A in equation B

3.5x+5(24-x)=97.5

3.5x+120-5x=97.5

solve for x

3.5x-5x=97.5-120

-1.5x=-22.5

x=15

Find the value of y

y=24-15=9
