Y=x^2-10x-18

Mathematics
1 answer:
BartSMP [9]3 years ago
3 0

Answer:

Vertex form is y=(x-5)^2-43

Step-by-step explanation:

Given expression: x^2-10x-18

Take half of b:

-10/2=-5

Square the result:

-5^2=25

Add and subtract into original expression:

x^2-10x+25-25-18

Factor and simplify:

(x^2-10x+25)-25-18

(x-5)^2-25-18

(x-5)^2-43

So the vertex form is y=(x-5)^2-43

Harlamova29_29 [7]

Answer:

For the unpaid amount of $38,200 IRS can assess either Mr.peterson or Mrs.Peterson for the entire deficiency as both are jointly and severally liable for the tax paid before they got divorced.

The graph of g(x) is obtained by reflecting the graph of f(x)=2|x| over the x-axis.
Lera25 [3.4K]
Answer: Choice C) 
g(x) = -|2x|

You get this answer by simply sticking a negative out front of the original function. In other words, g(x) = -f(x) or more technically, g(x) = -1*f(x).

The negative will flip every y coordinate from positive to negative (or vice versa)

You'll also use the idea that |2x| = 2|x|. The two can be pulled out since we can say |x*y| = |x|*|y|
So |2*x| = |2|*|x| = 2|x|

A fraction reduces to 36. If its denominator is 6x5, what is its numerator?
olchik [2.2K]
If you would like to find the numerator of a fraction, you can do this using the following steps:

denominator ... 6 * 5 = 30
numerator ... x = ?

36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080

The correct result would be 1080.
