Plot a graph of y-axis against x-axis.

The graph should be a straight line passing through:

(-2,0.8) , (-1,-0.4) , (0,0) , (1,0.4) and (2,0.8)

Select all of the equations that represent linear relationships.
ad-work [718]
There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.

So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.

Hope this helps! :)

at a shop on times square three''I love NY'' shirts sell every 10 minutes for $19.95 each.Every 45 minutes on Yankee's hat sells
Marizza181 [45]
I believe the answer 30,164.4
 
you multiply 19.95 by 3 and you get 59.85
then you figure out how many hours are from 9 am to 9 pm which was 12 then you multiply that by 6 then you take 59.85 and multiply that by 72 then you multiply that by 7

Which expressions can be used to find m∠ABC? Check all that apply.
valina [46]

Answer:

\cos^{-1}(\frac{6.3}{9.8})

\sin^{-1}(\frac{7.5}{9.8})

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The sine ratio is the length of the opposite side expressed over the hypotenuse.

\sin m\angle ABC=\frac{7.5}{9.8}

Take the sine inverse of both sides to get;

m\angle ABC=\sin^{-1}(\frac{7.5}{9.8})

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

\cos m\angle ABC=\frac{6.3}{9.8}

Take the cosine inverse of both sides to get;

m\angle ABC=\cos^{-1}(\frac{6.3}{9.8})
