Answer: This relation is not a function

Step-by-step explanation:

To find out if a relation is a function, we need to use the vertical line test, which means each input value only has one output value. This graph does not pass that vertical line test.

Y is directly related to X, and Yis 81 when X is 27.<br> The constant of variation is

Arisa [49]

Answer:

Step-by-step explanation:

A direct variation is of the form

y = kx

We know x and y so we can find k

81 = k *27

Divide each side by 27

81/27 = 27k/27

3=k

The constant of variation is 3

Robert mixed 113 liters of blue paint with 123 liters of red paint to make 3 liters of purple paint. To make a new batch of purp

MAVERICK [17]

Answer:

$Blue =1\frac{3}{5}$

Step-by-step explanation:

Given

$Blue = 1\frac{1}{3}$

$Red = 1\frac{2}{3}$

Required

Determine the amount of blue paint when Red = 2

To do this, we make use of the following equivalent ratios

$Ratio = Blue : Red$

When $Blue = 1\frac{1}{3}$ and $Red = 1\frac{2}{3}$

$Ratio = 1\frac{1}{3} : 1\frac{2}{3}$

When Red = 2

$Ratio = Blue : 2$

Equate both ratios

$Blue : 2 = 1\frac{1}{3} : 1\frac{2}{3}$

Convert to division

$\frac{Blue}{2} =1\frac{1}{3} / 1\frac{2}{3}$

Convert fractions to improper fraction

$\frac{Blue}{2} =\frac{4}{3} / \frac{5}{3}$

$\frac{Blue}{2} =\frac{4}{3} * \frac{3}{5}$

$\frac{Blue}{2} =\frac{4}{5}$

Make Blue the subject

$Blue =\frac{4}{5}*2$

$Blue =\frac{8}{5}$

$Blue =1\frac{3}{5}$
