Which function is the inverse f(x)=-5x-4
Kay [80]

Answer:

f⁻¹(x) = -(x+4) / 5

Step-by-step explanation:

Given function is :

f(x) = -5x-4

We have to find the inverse of given function.

Step 1.  Put y = f(x) in given function

y = -5x-4

Step 2. Add 4 to both sides of above equation

y+4= -5x-4+4

y+4 = -5x

Step 3.Divide by -5 to both sides of above equation

y+4 / (-5) = -5x / (-5)

-(y+4) / 5 = x

Step 4 . Swap sides

x = -(y+4) / 5

Step 5. Put x = f⁻¹(y) in above equation

f⁻¹(y) = -(y+4) / 5

Step 6. replace y with x

f⁻¹(x) = -(x+4) / 5 which is the inverse of f(x) = -5x-4.

4.84 times ten to the fifth power plus 3.9 times 10 to the second power plus 8.91 times 10 to the 7th power
lakkis [162]
Okay, so you didn't really put anything for me to know what you wanted to solve, so I'm going to assume this is Scientific Notation:
We have:
10^5 = 100,000  x 4.84 would be:  484,000
10^2 = 100 x 3.9 would be: 390
10^7 = 10,000,000 x 8.91 would be: 89,100,000

lisa's dog has 12 squeaky toys. one third of the dog's toys are squeaky toys. how many dog toys are squeaky?
AVprozaik [17]
The answer is that 4 dog toys are squeaky.

We are going to multiply 12 by 1/3 to find what one third of 12 is.
12*1/3
So when you multiply the numerators and denominators, you get 12/3 which can be simplified to 4.

Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into
ANEK [815]

Answer:

-3/5x + y = - 26/5

Step-by-step explanation:

First, I put everything in slope-intercept form, just because it's more simple for me.

y = 3/5x + b

Since we don't have b, we can use the coordinate they give us to solve for it.

-4 = 3/5 (2) + b

-26/5 = b

y = 3/5x - 26/5

Now, we can move the variables around to fit the form:

Ax + By = C

-3/5x + y = - 26/5

I hope this helped!
