Answer:

I think it's c

Step-by-step explanation:

because  a*1=1

All of the other statements are incorrect because for one a+0=0 Only 0 can = 0

A*0=1? A number times 0 is always going to be zero

A+1=1? Only 0 is the only number that a number plus 0 is the same number

Find (f*g)(x) when f(x)=x^2-7x+12 and g(x)=3/x^2-16
IgorC [24]

The answer is:  (f*g)(x)= \frac{3x-9}{x+4}

<u><em>Explanation</em></u>

Given functions are.......

f(x)=x^2-7x+12

g(x)= \frac{3}{x^2-16}

For finding (f*g)(x) , we just <u>need to multiply the two functions</u> f(x) and g(x). So......

(f*g)(x)= f(x)*g(x)\\ \\ (f*g)(x)= (x^2-7x+12)(\frac{3}{x^2-16})\\ \\ (f*g)(x)= [(x-3)(x-4)][\frac{3}{(x+4)(x-4)}]\\ \\ (f*g)(x)= \frac{3(x-3)}{x+4} = \frac{3x-9}{x+4}

Answer ASAP!!! Find the distance on the coordination system from the point (-3,4) to the point (8,-7).
alexdok [17]

Answer:

The answer to your question is: distance = 15.55 units

Step-by-step explanation:

Data

A (-3, 4)

B (8, -7)

Formula

distance = √((x2-x1)² + (y2-y1)²)

Substitution

distance = √((8- -3)² + (-7-4)²)

distance = √((8 + 3)² + (-7-4)²)

distance = √((11)² + (-11)²)

distance = √(121 + 121)

distance = √242

distance = 15.55 units
