Is the equation y=4x+1 proportional? * Yes No

Mathematics

Answer:

Step-by-step explanation:

y = 4x + 1 is not a direct variation. Direct variations have the form y = kx. So y = 4x would be a direct variation (k=4), but not y = 4x+1

Find the value of x and the value of y

serg [7]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

use Cos for y .... b/c we see that function above has all the pieces we are going to work with

use Sin for x .. for the same reason above

Cos(30) = y / 4 $\sqrt{2}$

4 $\sqrt{2}$ Cos(30) = y

4 $\sqrt{2}$ $\sqrt{3}$ /2 = y

2 $\sqrt{6}$ = y

leave the answer for y like that.. it's in 'exact" form

now for x

Sin(30) = x / 4 $\sqrt{2}$

4 $\sqrt{2}$ Sin(30) = x

4 $\sqrt{2}$ * 1/2 = x

2 $\sqrt{2}$ = x

and leave your answer for x like that as it's in it's exact form. :)

oh and I see the answer in the list.. do you? :)
