$\frac{5}{n} =\frac{1.5}{1.8} \\ \\ n\neq 0 \\ \\1.5n=5\cdot 1.8\\ \\1.5n= 9 \ \ / : 1.5 \\ \\ n=6$

5/n = 1.5/1.8 Multiply each side by 'n': 5= 1.5n/1.8 Multiply each side by 1.8 : 9 = 1.5n Divide each side by 1.5 : 6 = n =====<=======<== Easier: 5/n = 1.5/1.8 Perform the division on the right side: 5/n = 5/6 Multiply each side by 'n' : 5 = 5n/6 Multiply each side by 6 : 30 = 5n Divide each side by 5 : 6 = n

A line that passes through the points (–4, 10) and (–1, 5) can be represented by the equation y = (x – 2). Which equations also

lyudmila [28]

The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line.
Let find the equation of the line:
First compute the slope using formula:
<span> </span> $\frac{y_2-y_1}{x_2-x_1}= \frac{5-10}{-1-(-4)}= \frac{-5}{3}$
So the equation is in the form:
$y=\frac{-5}{3}x+s\text{ wherein s is another parameter. }$
For x=-4 we get the equation:
$10=\frac{-5}{3}(-4)+s$
Solving the above equation for s we get:
$s= \frac{10}{3}$
The equation then is the following:
$y=\frac{-5}{3}x+\frac{10}{3}$

The correct answer then is equation 2 and equation 3.

Identify the domain and range of each relationship. Represent the relation with a mapping diagram. Is the relation a function?

Ivenika [448]

Remember, to be a function, all elements in the domain should correspond to one element in the range.
The domain is the x coordinate, range is the y coordinate.
The domain we can solve for as the set {4.2, 5, 7}. The range is the set {0, 1.5, 2.2, 4.8}.
But we see that an element in the domain corresponds to more than one element in the range, thus making it not a function.
