Answer:

(x + 4) × (2x - 5)

Step-by-step explanation:

  • Begin by writing 3x as a difference
  • 2x^2 + 8x - 5x - 20

  • Factor out 2x from the expression
  • 2x × (x + 4) - 5x - 20

  • Factor out -5 from the expression
  • 2x × (x + 4) - 5 (x + 4)

  • Factor out x + 4 from the expression
  • (x + 4) × (2x - 5)

Hope this helps!!

In a rational function, is the horizontal shift represented by the vertical asymptote?
ziro4ka [17]
<h3>Short Answer: Yes, the horizontal shift is represented by the vertical asymptote</h3>

A bit of further explanation:

The parent function is y = 1/x which is a hyperbola that has a vertical asymptote overlapping the y axis perfectly. Its vertical asymptote is x = 0 as we cannot divide by zero. If x = 0 then 1/0 is undefined.

Shifting the function h units to the right (h is some positive number), then we end up with 1/(x-h) and we see that x = h leads to the denominator being zero. So the vertical asymptote is x = h

For example, if we shifted the parent function 2 units to the right then we have 1/x turn into 1/(x-2). The vertical asymptote goes from x = 0 to x = 2. This shows how the vertical asymptote is very closely related to the horizontal shifting.

Find the solution set of this equation.<br> y^2-11y=0 <br> separate the two values with a comma.
Tanya [424]

Answer:

0,11

Step-by-step explanation:

y^2-11y=0

y(y-11)=0 we have transformed the equation into a product

a product can be zero only if one of the factors is 0

so the two solutions are

y=0

and y-11=0  y=11
