Find the inverse of the one to one function. f(x)=2x+5/7

Answers

Answer 1

Answer: $f(x)=(2x+5)/(7)\n\n y=(2x+5)/(7)\n 7y=2x+5\n 2x=7y-5\n x=(7y-5)/(2)\n \boxed{f^(-1)(x)=(7x-5)/(2)}$

Solve 8m² + 20m = 12 for m by factoring

Please show all work

Answers

$8m^(2)+20m=12 / :2$
$4m^(2)+10m=6$
$4m^(2)+10m-6 =0$
$\Delta=b^(2)-4ac$
$\Delta=100-(4*4*-6)$
$\Delta=100+96=196$
$x1=(-b-√(\Delta))/(8)$
$x1=(-10-14)/(8)$
$x1=(-24)/(8)$
$x1=-3$
$x1=(-b+√(\Delta))/(8)$
$x2=(-10+14)/(8)$
$x2=(1)/(2)$

so you can write $8m^(2)+20m=12 / :2$ as

$8(m+3)(m-(1)/(2))=8*[m^(2)+2.5m-1.5]=0$

What is zero of a function?

Zero of a function is defined as the roots of the function for which the value of the function will be 0 at those points.

If p is the zero of the function f(x)=0 then f(p)=0.

We have,

f(x) = (x-1)² (x+3)³ (x+1)

Now,

The zero is located at x=1 and has a multiplicity of 2.

Because the number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity.

The zero is located at x = - 3 and has a multiplicity of 3. The graph of the function will touch, but not cross, the x-axis at the x - the value of 1.

The complete question is given below:-

Consider polynomial function f f(x)=(x-1)^2(x+3)^3(x+1)

use the equation to complete each statement about this function

The zero located and x=1 has a multiplicity of __ and the zero located at x=-3 has a multiplicity of __. The graph of the function will touch, but not cross, the x-axis at the x-value of __.

Which of the sets shown includes the elements of set Z that are both odd numbers and multiples of 7?Z={-21, -14, -7.0, 7, 14, 21}
A {-21, 21)
B. {-21.-7. 7. 21)
C: {-14, 0.14)
D. {-21, -14, -7)

Answers

Answer:

B. {-21.-7. 7. 21)

Step-by-step explanation:

The set made up of odd numbers and multiples of 7 is given as;

{-21.-7. 7. 21)

Multiples of 7 are usually those numbers where 7 is factor.

Odd numbers are numbers that cannot be divide by 2.

So, the most fitting answer is B.

Consider the following system of equations.Y=3x-7
Y-3x=5
What can you conclude about the system of equations?

The system if equations is inconsistent.

The system of equations is dependent.

The system of equations is independent.

None of these.

Answers

The given equation: y = 3x -7 and y - 3x = 5
Before we answer, let’s solve the given equation:
=> y – 3x = -7
=> y – 3x = 5
=> Subtract both equation. Cross out y – 3x, thus the remaining would be
=> -7 and 5; in where -7 is not equals to 5

Thus the system of equations is inconsistent because an inconsistent system has no solution.
And there is no solution found of the given equations.
