Simplify the following expression. 4a^-2b<br><br> A.) b/4a^2<br> B.)4b/a^2<br> C.)1/4a^b2

Sergio [31]

ANSWER

The correct answer is B

$\frac{4b}{ {a}^{2} }$

EXPLANATION

The given exponential expression is

$4 {a}^{ - 2} b$

We can rewrite this as,

$4b \times {a}^{ - 2}$

We need to simplify to obtain a positive index, so we apply the following property,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

This implies that,

$4b \times {a}^{ - 2} = 4b \times \frac{1}{ {a}^{2} }$

This will finally simplify to,

$4b \times {a}^{ - 2} =\frac{4b}{ {a}^{2} }$

Therefore the correct answer is B

−9x+4y=6 9x+5y=−33

blsea [12.9K]

Answer:

{x,y} = {-2,-3}

Step-by-step explanation:

System of Linear Equations entered :

[1] -9x + 4y = 6

[2] 9x + 5y = -33

Graphic Representation of the Equations :

4y - 9x = 6 5y + 9x = -33

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 5y = -9x - 33

[2] y = -9x/5 - 33/5

// Plug this in for variable y in equation [1]

[1] -9x + 4•(-9x/5-33/5) = 6

[1] -81x/5 = 162/5

[1] -81x = 162

// Solve equation [1] for the variable x

[1] 81x = - 162

[1] x = - 2

// By now we know this much :

x = -2

y = -9x/5-33/5

// Use the x value to solve for y

y = -(9/5)(-2)-33/5 = -3

Answer:

1.15 miles closer

Step-by-step explanation:

you just subtract 1 3/5 from 2 3/4

1 3/5 = 1 12/20

2 3/4 = 2 15/20

2 15/20- 1 12/20 = 1 3/20 = 1.15
