(f.g)(x) = (4x + 6)(-5x) = -20x^2 -30x
ok done. Thank to me :>
Answer:
30 ft
Step-by-step explanation:
you use 35x sin(60) because 35 is the hypotenuse and the angle is 60 degrees
The y-intercept is 7500 and it represents when the account is still active or have been inactive for 0 years.
Answer:
D
Step-by-step explanation:
For this one, you want to solve it similarly to linear equations.
-13x+11<-24x by adding 24x to both sides becomes 11x<11.
From there, you divide by 11 to isolate x, leaving x<1.
Since the equation has a < symbol (not ≤), the dot is not filled in. X is less than 1, so the arrow goes to the left, making it D.

Answer:
130°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
60° + 70° = x
130 = x
