Answer:
Each friend got 6 cars each
Step-by-step explanation:
17-5= 12 cars
He gave 12 cars away.
Since there are 2 friends, you divide the cars given away by 2, hence
12/2= 6
Area = (3x-5)(x-4) =
3x² - 12x - 5x + 20 =
3x² - 17x + 20
Answer:
a. x - 2y = 4
Step-by-step explanation:

The value of y varies directly as the square of x and y = -12 when x = 2 then the value of y when x = -4 exists y = 24.
<h3>What is meant by direct variation?</h3>
When two variable quantities contain a constant ratio, their relationship exists comprehended a direct variation. It exists said that one variable varies directly as the other. The formula for direct variation is y = kx, where k exists the constant of variation.
The constant value (often written k) relating amounts that rise or fall uniformly together. It exists the ratio of the amounts y and x:
k = y/x.
Put another way: y = kx.
Accordingly, the equation has the form y = kx, where k may be any number.
Substituting y = -12 when x = 2, we get
-12 = k × 2
simplifying the above equation, we get
⇒ k = -6
Therefore, the required equation exists y = -6x.
The value of y when x = -4 is y = -6 × -4 = 24.
