Answer:
B
Step-by-step explanation:
-5[ (x³+1)(x+4) ] = -5[ x³*(x+4) + 1*(x+4) ]
= -5 [ x³*x + x³*4 + 1*x + 1*4 ]
= -5 [ x⁴ + 4x³ + x + 4]
= -5*x⁴ + (-5)*4x³ + (-5)*x + (-5) * 4
= -5x⁴ - 20x³ - 5x - 20
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (18, 26)
m = 
=

Answer:
f(12) = 11
Step-by-step explanation:
To solve this question:
- Substitute x = 12 into the equation: f(12) = 3/4 (12) + 2
- Simplify: 3/4 × 12 = 36/4 which is 9 → f(12) = 9 + 2
Hope this helps!
That depends on if there is a 90-degree angle within the triangle or not.
