An inverse of the function is when you switch the variables around, or solve for f(x). I'm going to make f(x) y, because it is just the same thing. So y=4x. Divide by 4, so x=y/4. Then you can switch the variables so y is on the outside, or the dependent variable, and the answer is y=x/4, or y=1/4x.

To find the inverse function, interchange the variables and solve for y.

f⁻¹ (x)= x/4

bonufazy [111]

Answer:

Idk if its multiple choice but you can do 1 of 2 ways theres using distance formula =√(5-3)sq+(1-4)sq

=√4+9

=√13 <--

or

3.6 units

Given: The two points that are P(5,1) and Q(3,4).

To find: The distance between these two points.

Solution: It is given that there are two points that are P(5,1) and Q(3,4).

The distance between these two points can be found out as using the distance formula that is: 3.6

Thus, the distance between the given two points is 3.6 units.

8X +6Y+4<br> Y=-3X+9<br> using substitution what numbers are the variables X and Y
Svetach [21]

Answer:

(5,6)

Step-by-step explanation:

8X +6Y=4

Y=-3X+9

Substitute the second equation into the first.  Every place you see y put -3x+9)

8x +6(-3x+9)=4

Distribute

8x-18x +54 = 4

Combine like terms

-10x +54 = 5

Subtract 54 from each side

-10x +54-54=4-54

-10x = -50

Divide by -10

-10x/-10 = -50/-10

x= 5

Now we need to find y

y = -3x+9

y = -3(5) +9

y = -15+9

y= 6
