5x = 2x + 9, where 5x > 0 and 2x + 9 > 0 ;
Then, 3x = 9 ;
Then, x = 3 ;
Verify : 5 × 3 = 2 × 3 + 9 ;correct !
5 × 3 > 0 ; correct !
2 × 3 + 9 > 0; correct !
B)
así que si usted toma el número sesenta dos entonces se obtiene cuarenta y seis
B because to be perpendicular the slope had to be opposite of the original slope but the same b. But parallel would be the exact same slope with a different b
Answer:
Step-by-step explanation:
Answer:
f'(x) = 2x + 
Step-by-step explanation:
differentiate using the power rule
( a
) = na
Given
f(x) = x² - 
+ 9 = x² - 4
+ 9 , then
f'(x) = 2x + 12
= 2x +
=
=
