Aleks04 [339]

Answer:

y = mx + b

y = -2x + 4

Step-by-step explanation:

m = 2 - 4 / 1 - 0 = -2 / 1 = -2

m (slope) = -2

y = mx + b (0,4)

4 = -2x + 0

<u>-0 - 0</u>

<u>4</u> = <u>-2x</u>

-2 -2

-2 = x

Equation: y = mx + b

y = -2x + 4

Is this correct if not which one is and why

zheka24 [161]

I believe the smallest would be D since even though B is a decimal with a lot of zeros in front of the #, B is still a positive # and D is a negative number being lower in the # line, so D or -200 would be the smallest

Jonathan's Antiques purchased an old wooden sled at an auction for $210. Jonathan wants to mark up the sled 60% of the selling p

Elis [28]

Well, if the selling price was 210, and that's the 100%, then if he adds 60% to that, the new price will be 160% of 210... well, if 210 is the 100%, what's 160% of that?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
210&100\\
x&160
\end{array}\implies \cfrac{210}{x}=\cfrac{100}{160}$

solve for "x".
