Answer:

The answer to your question is: letter B

Step-by-step explanation:

Data

°C °F

0 32

35 95

Process

Find slope m = (95 - 32) / ( 35 - 0)

m = 63 / 35

m = 9/5

Line equation

( y - y1) = m(x - x1)

y = °C x = °F

°C - 0 = 9/5 ( °F - 32)

°C = 9/5( °F - 32)

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
