“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].
Direct variation is written in the form y = k * x or x = y * k. And, inverse variation is written in the form y = k/x or x = y/k.
For the first problem, if we isolated the y, we would get:
4y = 3x - 1
y = (3/4)x - 1/4
This is written as y = mx + b, which isn’t the form of direct or inverse variation, so the answer is NEITHER.
For the second equation, we could divide by 2 on both sides to isolate x and see if it is in the correct form:
x = 4/y
This is inverse form, so the second question is INVERSE with a constant of variation as 4.
Answer:
x = 2.7
Step-by-step explanation:
The given equation is :
We need to solve it for x.
It can be rewrite as follows:
Adding 10 to both sides,
So, the value of x is equal to 2.7.
