Hello! A diagram is a function, when the domain of a number only has one range. By looking at this graph, A is eliminated, because 1 has more than one range. Exact same thing with C. The only diagram that shows a function is B, because no domain has more than one range. All of the numbers have one range, and that diagram makes a function. The answer is B.

Write this equation in standard form: (4, -1) m = 3

ziro4ka [17]

Standard form looks like this: Ax + By = C.

y - (-1) = 3(x - 4)

y + 1 = 3x - 12

y = 3x - 12 - 1

y = 3x + 13

Move 13 to left side and y to right side.

-13 = 3x - y

Done!

Leo reads 13 pages in 1/3 hour?

yuradex [85]

A) there are 3 times 1/3 in each hour: so we have to multiply the original number by 3: 3*13=39!!

b)

so, 13 pages in 1/3 of an hour

for this we have to divide the time needed for the 13 pages by 13:

$\frac{1}{3*13} = \frac{1}{39}$

so each page requires $\frac{1}{39}$ of an hour, which is approximately 1.5 minutes.
