Answer: C. f(x)=1.5x
Step-by-step explanation:
Here's the complete question:
In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation
A-f(x)=6x
B-f(x)=4x
C-f(x)=1.5x
D-f(x)=0.67x
The direct variation equation will be:
6 = kx
When x = 4, this will be:
6 = 4k
k = 6/4
k = 1.5
Therefore, the direct variation equation is: f(x)=1.5x
2b² - 3b + 4a²
= 2(8)² - 3(8) + 4(-6)²
= 2(64) - 24 + 4(36)
= 128 - 24 + 144
= 248
