Answer:

15x2 - 62x + 40

Step-by-step explanation:

(10 - 3x)(4 - 5x)= 10 x 4 + 10 x -5x - 3x x 4 - 3x x -5x = 15x2 - 62x + 40

f(x) is a parabola, now you have to graph

Answer:

x=10/-3, 4/5

Step-by-step explanation:

f(x) = (10 - 3x)(4 - 5x)

10-3x=0

-3x=-10

x=10/3

4 - 5x = 0

-5x = -4

x = 4/5

Is this an example of direct variation? f(x)=2xy

docker41 [41]

Answer:

Yes, it is:

Step-by-step explanation:

Given

$f(x) =2xy$

Required

Determine if it is a direct variation

A direct variation is represented as:

$f(x)\ \alpha\ x$

Express as equation

$f(x) = kx$

Compare $f(x) = kx$ to $f(x) =2xy$

$k = 2y$

<em>Hence, it is a direct variation</em>
