Please help Show that the inverse of a linear function y=mx+b, where m≠0 and x≠b, is also a linear function
Let f(x) = mx+b. Also, let g(x) be the inverse of f(x)
To find the inverse, we start with y = mx+b and swap x and y. From there, we solve for y like so
y = mx+b
x = my + b
x-b = my
my = x-b
y = (x-b)/m ... note m is in the denominator, so m cannot be 0
y = (x/m) - (b/m)
y = (1/m)x - (b/m)
g(x) = (1/m)x - (b/m)
This new equation is linear because it is in the form (slope)x+(y intercept)
The new slope is 1/m and the new y intercept is -b/m
So this proves that the inverse g(x) is linear when f(x) is linear.
The inverse function is:
[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]
Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].
---------------------------------
A linear function is given by:[tex]y = mx + b[/tex]
In which:
m is the slope and b is the y-intercept.To find the inverse function, we exchange x and y in the original function, and then isolate y. Thus:[tex]x = my + b[/tex]
[tex]my = x - b[/tex]
[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]
Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].

Given the following equation, solve for c.
Answer:
c = b/a
Step-by-step explanation:
Solve for c:
b/c = a
Hint: | Transform b/c = a so that c only appears in the numerator.
Take the reciprocal of both sides:
c/b = 1/a
Hint: | Solve for c.
Multiply both sides by b:
Answer: c = b/a
find 4 different solution for 2x-y-4=0
Answer:
x=3 y=1
x=4 y=2
x=5 y=3
x=6 y=4
Step-by-step explanation:
add y to both sides to get:
2x-4=y
pull out the 2 from 2x-4 to get:
2(x-2)-y = 0
We need to know that x-2 cannot equal 0 or else the solution will be negative. So we need to make x-2 equal to any other number that is not negative and make y the inverse of x-2 so they cancel out and be zero. so some solutions are:
x=3 y=1
x=4 y=2
x=5 y=3
x=6 y=4

Write a function g whose graph represents a reflection in the y-axis of the graph F(x)=-x+1
Answer:
[tex]\bold{g(x) = x+1}[/tex]
Step-by-step explanation:
Given a function:
[tex]F(x) =-x+1[/tex]
To find:
Function [tex]g[/tex] whose graph is a reflection in the y -axis for the given function = ?
Solution:
First of all, let us learn about the reflection of a point ([tex]x, y[/tex]) in y axis.
For example, let us consider a point (3, 2) on the coordinate axis.
The reflection of this point in y axis will be (-3, 2)
OR
In other words, To find the image of a point in y axis:
the x coordinate is made of negative sign and y coordinate remains the same.
A line is nothing but a number of points joined together.
So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.
Given that [tex]F(x) =-x+1[/tex]
We can write it as:
[tex]F(x)=y =-x+1[/tex]
To find its reflection:
[tex]g(x) = - (-x)+1\\\Rightarrow \bold{g(x) = x+1}[/tex]
Please refer to the attached graphs of [tex]F(x)[/tex] and [tex]g(x)[/tex] .
So, the answer is:
[tex]\bold{g(x) = x+1}[/tex]
5 times the sum of the digits of a two digit number is 9 less than the number formed by reversing its digits. If 4 times the value of the digit at ones place is equal to the half of the place value of the digit at tens place, find out the number.
Answer:
5 times the sum of the digits of the number is 9 less than the number formed by reversing digits. → x = (5y - 9)/4 -- equation (1). Case - 2 : And, 4 times the value of the digits at ones place is equal to half the place value of digit at tens place (10x/2).

Y/8=5 I don’t know where to start
Answer: y = 40
Explanation: In this problem, notice that y is being divided by 8 so to
get y by itself, we need to multiply both sides of the equation by 4.
So we have (8)(y/8) = (5)(8).
Noice that on the left side, the 8 and 8
cancel each other out so we're just left with y.
On the right side, we have (5)(8) which is 40.
So we have y = 40.
Answer: so what you want to do is you have the equation.
Y/8=5
so you can just say it's Y divided by 8 = 5.
The inverse operation of division is multiplication.
so know it would be y×8=5. so you would multiply 8 by 5. which would be 40 so y=40. a way to check it is subsituting 40 for Y. 40/8=5

An account pays 8% per year simple interest paid a new one, the amount in the account is $850. How much is the account in year 6?
Answer:
1258
Step-by-step explanation:
SI = (P x R x T) / 100
SI = Simple Interest
P = Principal
R = Rate
T = Time
SI = (850 x 8 x 6)/100
=> SI = 85 x 8 x 6 /10
=> SI = 680 x 6 /10
=> SI = 68 x 6
=> SI = 408
The total amount after 6 years = Principal + Simple Interest
=> Total Amount = 850 + 408
=> Total Amount = 1258
After 6 years, the amount in account is 1258.

Find the GCF of the terms of the polynomial.
====================================================
Explanation:
The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.
----------
For the variable portions, we can
write z^5 as z^3*z^2write z^4 as z^3*z^1write z^3 as z^3*1Each time we see z^3 show up, so this is the largest common factor among the three variable terms.
----------
The two results we got were 2 and z^3
Putting the two results together, we end up with the overall GCF of 2z^3

A debt of $17 is a larger value than a debt of $20.
One half an apple is equivalent to 8 fourths apples.
8.01 is a smaller increase in sales then 8.001.
LaTeX: \frac{2}{3} 2 3 below zero is a lower temperature than 6 below zero.
Answer:
The statement that is true is:
A debt of $17 is a larger value than a debt of $20.
Step-by-step explanation:
Let us look at the statements one after the other to determine if they are true or not:
1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$
2) One half an apple is equivalent to 8 fourths apples:
one half an apple = [tex]\frac{1}{2}\ of\ an\ apple[/tex]
8 fourths of an apple = [tex]\frac{8}{4} = \frac{2}{1}\ of\ and\ apple[/tex]. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.
3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:
8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009
4) [tex]\frac{2}{3}\ below\ zero[/tex] is a lower temperature than 6 below zero:
[tex]\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ[/tex]
6 below zero = - 6°
On the number line, -6 is smaller than [tex]-\frac{2}{3}[/tex] hence the statement is false.
Can someone help? 15 points! :)
Answer:
[tex]\Large \boxed{\mathrm{see \ below}}[/tex]
Step-by-step explanation:
Given.
(4x)/7 - 6 = -20
The x variable should be isolated on one side of the equation.
Adding 6 to both sides of the equation.
(4x)/7 - 6 + 6 = - 20 + 6
(4x)/7 = - 14
Multiplying both sides of the equation by 7.
(4x)/7 × (7) = - 14 × (7)
4x = - 98
Dividing both sides of the equation by 4.
(4x)/4 = - 98/4
x = - 24.5

-7 - p= p +3
How do you do this
Answer:
-5 = p
Step-by-step explanation:
-7 - p= p +3
Add p to each side
-7 - p+p= p+p +3
-7 = 2p+3
Subtract 3 from each side
-7-3 = 2p+3-3
-10 = 2p
Divide each side by 2
-10/2 = 2p/2
-5 = p
