Question

A couple quick algebra 1 questions for 50 points!

Answer 1

Answer:

Question 6) Neither (Not an inverse variation)

Question 7) Inverse variation

Question 8) Inverse variation

Step-by-step explanation:

These are the two formulas we need to know prior to solving the question.

Direct variation: c times x

Inverse variation: c times 1/x --> c/x

- Here, c is the constant

6. y = x + 7

This is neither. It is not in the form of a direct, or inverse variation, so it does not belong in any category.

7. 14 = xy

This equation is an inverse variation.

xy = 14

y = 14/x

14 is the constant, and the format is the same as for an inverse variation.

8. x = -8/y

This equation is an inverse variation.

yx = -8

y = -8/x

-8 is the constant, and the format is the same as for an inverse variation.

So we can conclude that questions 7 and 8 is an inverse variations, while question 6 isn't.

Answer 2

General forms

Direct

• y=Kx

Inverse

• y=k/x

so

#6

• y=x+7

Not inverse and direct also as 7 is present

#7

• 14=XY
• y=14/x

Yes

#8

• x=-8/y
• y=-8/x

Yes
