Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2

Step-by-step explanation:
Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .
<u>Step-by-step explanation:</u>
Here we have , Bruce saved $ 35.00 to buy a new video game. The game's original price was $ 42.00 , but it was on sale for 30% off. The sales tax rate was 5%. We need to find Did Bruce have enough money to buy the game .Let's find out:
We have , Bruce saved $ 35.00 to buy a new video game . The game's original price was $ 42.00 , but it was on sale for 30% off. i.e.
Price =

⇒
Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .
For the first equation, start from 4 on the y axis and go up one over to the right one (repeat). For the second equation, start on the 2 on the y axis and go down one and to the right one (repeat). Also a tip, look up Desmond Graph Calculator. Desmos can show you what the graph will look like when you enter it in like shown in the picture I have sent.
