“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
Murljashka [212]

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.

Solve the following equation or inequality for the unknown variable. Round answer to two decimal places if necessary.
Sonbull [250]

Answer:

x = 2.7

Step-by-step explanation:

The given equation is :

(3x)^2-10=56

We need to solve it for x.

It can be rewrite as follows:

9x^2-10=56

Adding 10 to both sides,

9x^2-10+10=56+10\\\\9x^2=66\\\\x=\sqrt{\dfrac{66}{9}}\\\\x=2.70

So, the value of x is equal to 2.7.
