Answer:

y = 1.5x

Step-by-step explanation:

in the graph you can see that when y=2, x= 3 and this graph is linares (im sorry if its not the right word). so this means for every 3gal of white paint youll need 2 gal of red paint. so 2y=3x: y = 3/2x

Which figure could be rotated the least amount of degrees to be carried onto itself

jeka94

Regular octagon.
Regular shapes take the least amount of degrees to rotate on themselves. However, out of all of them, the octagon has the most sides and thus also the least amount of degrees in rotating.

Hope this helps :)

Which rational number equals 0 point 4 with bar over 4?

Ulleksa [173]

<h3>Answer: 4/9</h3>

==============================================

Work Shown:

$x = 0.\overline{4}\\\\x = 0.4444\ldots\\\\10x = 4.4444\ldots\\\\10x-x = 4.4444\ldots-0.4444\ldots\\\\9x = 4\\\\x = \frac{4}{9}\\\\\frac{4}{9} = 0.\overline{4}= 0.4444\ldots\\\\$

The idea is that when we subtract 10x and x, the infinite decimal pattern (the 4s that go on forever) will cancel. That leads to 9x = 4 which solves to x = 4/9

Answer: Slope: -1 Y-intercept: -4

Step-by-step explanation:

Slope formula:

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

$m=\frac{-13 -(-6)}{9-2}= m=\frac{-13 + 6}{9-2}$

$m=\frac{-7}{7\\}$

m = -1

When you draw this on the graph, the y-intercept is -4.

y = -4

Use the law of cosines to find the length of a

borishaifa [10]

Answer:

Step-by-step explanation:

You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:

$\frac{sin55}{175}=\frac{sin42}{a}$ and solving for a:

$a=\frac{175sin42}{sin55}$ so

a = 143.0
