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

we know that in direct variation as x increase y also increases.

in indirect variation x decreases y increase and vice versa.

in part a we have x at top (numerator ) and y at denominator it mean indirect variation (as x increases y decreases).

to find k we know that for indirect variation xy=k

if we rewrite the equation x=9/y we get xy=9

which mean k=9 .

in part b we have 4xy=20 if we simplify this equation we get

xy=20/4=5

so here if we rewrite in terms of x.

we get x=5/y which represents indirect variation.

and we know xy=k

we have xy=5 .so k=5

(pls also provide an explanation for how i do this)
Marizza181 [45]

Answer:

slope = \frac{3}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 3 ) and (x₂, y₂ ) = (9, 6 )

m = \frac{6-3}{9-5} = \frac{3}{4}

A proper fraction is converted to a decimal equivalent by dividing the denominator into the numerator. True
kondaur [170]

False, it's the other way around: you divide the numerator by the denominator.

For example, to evaluate \frac{8}{15} you divide 8 by 15:

\dfrac{8}{15} = 8\div 15 = 0.5\overline{3}
