Answer:
70 degrees
Step-by-step explanation:
x = angle
180 - x = it's supplement
90 - x = it's compliment
(180 - x) - 4(90 - x) = 30
180 - x - 360 + 4x = 30
reducing
3x = 210
x = 70
Answer:
-8/3
Step-by-step explanation:
find slope
(-1,5) ( 2,-3 )
(-3 -5)/( 2-(-1)) = -8/3
The value of f(2) is -2 ⇒ 1st answer
Step-by-step explanation:
The form of the quadratic function is;
f(x) = ax² + bx + c, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
- x is the domain of the function and f(x) is the range of the function
∵ f(x) = -5x² - x + 20
- f(2) means value f(x) at x = 2
∵ x = 2
- Substitute x in the function by 2 to find f(2)
∵ f(2) = -5(2)² - (2) + 20
∴ f(2) = -5(4) - 2 + 20
∴ f(2) = -20 - 2 + 20
∴ f(2) = -2
The value of f(2) is -2
