Answer:

P = -1

Step-by-step explanation:

3(2p-1)-2(3p+4)=11p

Distribute:

6p-3-6p-8=11p

Combine like terms:

-11 = 11p

Solve for p by dividing by 11:

-11/11 = 11p/11

Simplify:

-1 = p

Let y be f(x)

[tex]\\ \sf\longmapsto y=4x-12[/tex]

Swipe the values

[tex]\\ \sf\longmapsto x=4y-12[/tex]

Isolate y

[tex]\\ \sf\longmapsto 4y=x+12[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{x+12}{4}[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{1}{4}x+3[/tex]

Hence.

[tex]\\ \sf\longmapsto f^{-1}(x)=\dfrac{1}{4}x+3[/tex]

Let y=f(x)

y=4x-12

Now interchange the variables

x=4y-12

The y we need now

x+12=4y

Divide both sides by 4

y=(x+12)/4

This is the inverse

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12

Answers

Answer:

x = 4

x = 6

x = 7/2

Step-by-step explanation:

Solve 5x + 2 = 22:

5x+2-2=22-2 (subtract 2 from both sides)

5x=20

x=4

Solve 2x-5=7

2x-5+5=7+5 (add 5 to both sides)

2x=12

x=6

Solve 2x+5=12

2x+5-5=12-5 (subtract 5 from both sides)

2x=7

x= 7/2

Solve 5x + 2 = 22

=> 5x + 2 = 22

=> 5x = 22 – 2

=> 5x = 20

=> x = 20/5

=> x = 4

Solve 2x-5=7

=> 2x - 5 = 7

=> 2x = 7+5

=> 2x = 12

=> x = 12/2

=> x = 6

Solve 2x+5=12

=> 2x + 5 = 12

=> 2x = 12-5

=> 2x = 7

=> x = 7/2

A pet store has 15 birds and 75 fish.
In simplest form, what is the ratio of birds to fish in the pet store?
O1/6
O1/5
O5/1
I don't know

Answers

Answer:

1/5

Step-by-step explanation:

For every bird in the store there will be 5 fish.

Because there is 5 times more fish then birds.

Using the ratio concept, the number of birds to fish expressed as a ratio is 1/5

Given the Parameters :

Number of birds = 15 Number of fishes = 75

Ratio of the number of birds to fish can be expressed thus :

Number of birds : Number of fishes

15 : 75

Divide both sides by 15

1 : 5

Hence, the ratio of birds to fish is 1/5

Answers

Step-by-step explanation:

5⁴×5² = 5⁶

10⁶/10³ = 10³

so, we have 5⁶/10³ = 15.625

and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.

so, 15.625 as plain number is

1.5625 × 10¹ in scientific notation.

therefore option 1 is correct.
