the solution of this equation is 3 and -3/2

Step-by-step explanation:

since it is quadratic equation, it has twp solutions

2 $k^{2}$ = 9 + 3k

or, 2 $k^{2}$ - 3k - 9 = 0

or, 2 $k^{2}$ - 6k + 3k - 9 = 0 ( by middle term factor)

or, 2k(k - 3) + 3(k - 3) = 0

or, (k - 3) (2k +3) = 0

so, k = 3 and -3/2

If f(x)=4(3x-5), find f^-1(x)

Margaret [11]

Answer:

f^-1(x) = (x+20) / 12

Step-by-step explanation:

f(x) = 4(3x-5)

Let y be the image of f.

y = 4(3x-5)

y = 12x-20

y+20 = 12x

x = (y+20) / 12

f^-1(y) = (y+20) / 12, so

f^-1(x) = (x+20) / 12

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The

Tanzania [10]

x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Volume of small box = 10 cubic feet

Volume of large box = 24 cubic feet

Total boxes shipped = 23

Combined volume = 426 cubic feet

Let,

x represent the number of small boxes.

y represent the number of large boxes.

x+y=23

10x+24y=426

x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
