Mathematics
1 answer:
Anestetic [448]3 years ago

Answer:

B) f^-1(x)=3-5x

Step-by-step explanation:

y=3-x/5

rearrange the equation so you have x variable on the left side

5y=3-x

+x     +x

5y+x=3

-5y      -5y

x=3-5y

so answer is b)

f^-1(x)=3-5x

Mary is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect? Which coordinates if they do? Negat
Umnica [9.8K]

Answer:

The graphs of the two function will not intersect.

Step-by-step explanation:

We are given a quadratic function f(x).

Also g(x) is given by a set of values as:

 x            g(x)

 1              -1

  2             0

  3              1

As g(x) is a linear function hence we find out the equation of g(x) by the slope intercept form of a line: y=mx+c

let g(x)=y

when x=1 ,   g(x)=-1

-1=m+c----(1)

when x=2   , g(x)=0

0=2m+c------(2)

Hence, on solving (1) and (2) by method of elimination we get:

m=1 and c=-2

Hence, the equation of g(x) is:

g(x)=x-2

So clearly from the graph we could see that the graph of the two functions will never intersect.

Answer:

The following tells what variable terms are and a explanation. I hope this is helpful

Step-by-step explanation:

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. ... In , the terms are: 5x, 3y, and 8. When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.
