Find a unit rate using a graph understanding proportional relationship by relating grapha and equation
Answer:
Domain:
Step-by-step explanation:
The domain of a function is all values of x such that f(x) exists.
In our case we have the following function:

We know that x and f(x) are real numbers, therefore the domain will be the interval
, or in other words, the domain is all real numbers.
I hope it helps you!
Answer:
-3 = -2
Step-by-step explanation:
3 (x + 1) - 6 = 5x - 2 (1 + x)
3x + 3 - 6 = 5x - 2 - 2x
3x - 3 = 5x - 2 - 2x
3x - 3 = 3x - 2
= -3 = -2
Answer : 29.5°
Given r = 10, q = 20, and Q = 100°
From the attached figure we can see that two sides and one angle is given
We use sine rule to find angle R

In triangle QRS

r = 10, q = 20, and Q = 100°

Replace all the values


=sin R
0.4932403876 = sin (R)
R= 
R= 29.5 degrees
