The line x=4 is a straight vertical line. If we were to measure it's slope using rise over run, we will get 0 in the denominator because there is no change in the x direction. Therefore, the slope of the line is undefined.

The function f is defined by f(x) = x^2 + 3x -10 , if f(x + 5) = x^2 + kx + 30, k=
boyakko [2]

Answer:

k = 13

Step-by-step explanation:

substitute x = x + 5 into f(x) , that is

f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL

          = x² + 10x + 25 + 3x + 15 - 10

         = x² + 13x + 30

compare this with f(x + 5) = x² + kx + 30

for the 2 expressions to be equal , then k = 13

Grace [21]

Answer:

Width = 4m

Length = 12 m.

Step-by-step explanation:

Let width = x, then length = 3x.

Perimeter

= 2(3x + x) = 32

2 * 4x = 32

x = 32 / 8 = 4 m.

The length = 3*4 = 12m and width = 4 m.
