5. Which of the following is the equation of a line. that passes through the points (0.8) and (6.4)7 Use of

See in the explanation

<h2>Explanation:</h2>

In this exercise, <em>we have the following points:</em>

$(0.8) \\ \\ (6.4)$

And <em>the following linear equations:</em>

$(1) \ y=-x+8 \\ \\ (2) \ y=\frac{3}{2}x+6 \\ \\ (3) \ y=-\frac{4}{5}x+4 \\ \\ (4) \ y=\frac{1}{2}x+8$

When plotting these graphs, we find the following facts:

We see the graph in the first figure below. The graph only passes through the point (0, 8)

This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the fourth graph below. The graph only passes through the point (0, 8)

So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>

Least common multiple of 30 25 4

White raven [17]

Answer:

The least common multiple of 30, 25, 4 is 150.

Step-by-step explanation:

The given numbers are 30, 25 and 4.

The factors of given numbers are

$30=2\times 3\times 5$

$30=5\times 5$

$4=2\times 2$

The L.C.M of given numbers is a smallest number that divides the given numbers completely.

$L.C.M.=\frac{2\times 3\times 5\times 5\times 5\times 2\times 2}{5\times 2}$

$L.C.M.=2\times 3\times 5\times 5\times 2=150$

Therefore the least common multiple of 30, 25, 4 is 150.
