How do i graph 3tan(x+30)

1 answer:

5 0

$y = 3tan(x + 30)$
$y = 3(\frac{tan(x) + tan(30)}{1 - tan(x)tan(30)})$
$y = \frac{3(tan(x) + tan(30))}{1 - tan(x)tan(30)}$
$y = \frac{3(tan(x)) + 3(tan(30))}{1 - tan(x)tan(30)}$
$y = \frac{3tan(x) + 3tan(30)}{1 - tan(x)tan(30)}$

Javier has a basket of oranges and apples. The number of oranges is 2 more than twice the number of apples in the basket. The di

Vesna [10]

Hello!

Let's put this into a system of equations and have a represent the apples and o represent the oranges.

o=2a+2
0.5o-0.5a=4

Since we can already so what o equals (2a+2) we will substitute it into the second equation and solve for a.

0.5(2a+2)-0.5a=4
1a+1-0.5a=4
1.5a+1=4
1.5a=3
a=2

Now that we know the value of a will put a into the first equation to find o.

o=2(2)+2
o=4+2
o=6

There were 6 oranges and 2 apples.

I hope this helps!

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2

vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40

40 pounds of Lemon Drops are needed
