Answer:

f(2h) = -4h + 9

Step-by-step explanation:

Jacob: Start with the given function f(x) = -2x + 9 and replace 'x' with 2h:

f(x) = -2x + 9 becomes:

f(2h) = -2(2h) + 9, or

f(2h) = -4h + 9

The first step when dividing 9m2 − 4m − 6 by 3m is shown. Which could be the next step? 3m − − 3m − − 3m − − 3m − −

Agata [3.3K]

Given:

Consider the below picture attached with this question.

The given expression is:

$\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}$

To find:

The next step.

Solution:

We have,

$\dfrac{9m^2}{3m}-\dfrac{4m}{3m}-\dfrac{6}{3m}$

Cancel out the common factors.

$=3m-\dfrac{4}{3}-\dfrac{2}{m}$

Therefore, the correct option is D.

Answer:

Step-by-step explanation:

A. 2 meters to centimeters

1 m = 100 cm

$2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2$

B)108 centimeters to meters

100 cm =1 m

$1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m$

C)2.49 meters to centimeters

1 m = 100 cm

$2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm$

D)50 centimeters to meters

100 cm = 1m

$1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m$

E)6.3 meters to centimeters

1 m = 100 cm

$6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm$

F)7 centimeters to meters

100 cm = 1 m

$1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m$

a)4 meters to millimeters

1 m = 1000 mm

$4 m = 4000 = 4 \times 10^3 mm$

b)1.7 meters to millimeters

1 m = 1000 mm

$1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm$
