v/13=11/7 solve for v

Let y be f(x)

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

Swipe the values

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

[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)

Now interchange the variables

The y we need now

Divide both sides by 4

This is the inverse

Solve for p by dividing by 11:

-11/11 = 11p/11

Simplify:

-1 = p

Step-by-step explanation:

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

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

=> 5x + 2 = 22

=> 5x = 22 – 2

=> 5x = 20

=> x = 20/5

=> x = 4

=> 2x - 5 = 7

=> 2x = 7+5

=> 2x = 12

=> x = 12/2

=> x = 6

=> 2x + 5 = 12

=> 2x = 12-5

=> 2x = 7

=> x = 7/2

Answer:

angle 4 is the alternate angle

Answer: (A) angle 1

Step-by-step explanation:

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.
