My guess is -1 because when a x value don’t got a number replace it with a 1

I think the answer would be -1 because normally you would place a 1 in front of x if it was negative, so I’m assuming you would do the same if it was -x and the one would just go after the negative symbol

Answer:

see below

Step-by-step explanation:

19-3 will be greater

We are multiplying 1/2 *(19-3) which is multiplying by a number less than 1 it will be less than 1

18-3 = 16

1/2 * (19-3)

Using PEMDAS

We do parentheses first

1/2 ( 16)

Then multiply

kondaur [170]

Answers:

1. No I don't agree with Selena because the area of the rectangle has the exact same area of the square

Step-by-step explanation:

1. square = x

rectangle length = 6 + x

rectangle width = x - 6

the plus 6 and minus 6 cancel each other out and make the same area that the square has.

Write an appropriate inverse variation equation if y = 9 when x = 3.

pav-90 [236]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
y=9\\
x=3
\end{cases}\implies 9=k3\implies \cfrac{9}{3}=k\implies \boxed{3=k}
\\\\\\
thus\qquad y=3x$
