Which expressions are equivalent to the equation

Ivahew [28]

Answer:

The correct answer is option 3

2⁻¹⁰ and 1/1024

Step-by-step explanation:

Points to remember

1). ( xᵃ)ᵇ = xᵇ

2). x⁻ᵃ = 1/xᵃ

It is given that, (2⁵)⁻²

To find the equivalent of (2⁵)⁻²

(2⁵)⁻² = 2⁻¹⁰

To find the value of 2⁻¹⁰

2⁻¹⁰ = 1/2¹⁰

2¹⁰ = 1024

1/2¹⁰ = 1/1024

Therefore the correct answer is 3rd option

2⁻¹⁰ and 1/1024

Helpppppp pleaseeeeee !!!!!!!!! !!!!

Sergio [31]

Given:

The function is:

$f(x)=6x-3$

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

$f(x)=6x-3$

Step 1: Substitute $f(x)=y$ .

$y=6x-3$

Step 2: Interchange x and y.

$x=6y-3$

Step 3: Isolate variable y.

$x+3=6y$

$\dfrac{x+3}{6}=y$

Step 4: Substitute $y=g(x)$ .

$\dfrac{x+3}{6}=g(x)$

Therefore, the inverse of the given function is $g(x)=\dfrac{x+3}{6}$ and the graphs of these functions are shown below.

Y=_x+4 x + 2y = 8 How many solutions dose this linear system have

jeyben [28]

Answer:

X=-1, y=4

Step-by-step explanation:

$y = x + 4 \\ x + 2y = 8 \\ = = = = = = = = = = = = \\ y - x = 4 \\ x + 2y = 8$

by using eliminating property

$3y = 12 \\ y = \frac{12}{3} = 4$

by substitution

X=-1
