0.4 divided by 0.08 show your work

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Since we have not instructed to follow any kind of rule dividing, we can write in any form. Let's calculate it using fraction

$0.4:0.08=\frac{0.4}{0.08}$

We can multiply both the nominator and denominator with 100

$\frac{0.4}{0.08}=\frac{40}{8}=5$

The answer is 5.

We can also solve it as a division of fractions:

$\frac{4}{10} : \frac{8}{100} = \frac{4}{10} * \frac{100}{8} = \frac{10}{2} = 5$

Which of the following is a correct equation for the line passing through the point (-1,4) and having slope m=-3

timurjin [86]

Answer:

y = -3x + 1

Step-by-step explanation:

Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line: y - k = m(x - h) becomes y - 4 = -3(x + 1), or:

y = -3x - 3 + 4

y = -3x + 1 This is the same as answer choice (b).
