Answer: 5(x-1)
Step-by-step explanation:
The value of f(19) in the given equation is 55.
<h3>What is the function of a linear equation?</h3>
The function of a linear equation illustrates a straight line graph and for a given set of input into the function, there is usually a specific output.
Given that:
We are to find the f(x) = 19.
So;
f(19) = 3(19) - 2
f(19) = 57 - 2
f(19) = 55

Divide 235/5 so 47 check by doing 47 times 5 it checks so the answer is 47
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
4
Cos(30) = y
4
/2 = y
2
= y
leave the answer for y like that.. it's in 'exact" form
now for x
Sin(30) = x / 4
4
Sin(30) = x
4
* 1/2 = x
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? :)
Answer:
angle y is 64⁰
Step-by-step explanation:
There are 2 ways to solve this.
first,
they are alternate angles
second,
you can solve by
180-64=116 (on a straight line)
180-116=64⁰
I'm not really good at explaining but hope this helps :)
