Answer:
-1/6
Step-by-step explanation:
A suitable calculator can evaluate this for you and show you the result as a fraction.
You start with the multiplication in the inner-most set of brackets. Here, those brackets are the absolute value function.
-2(-1/3) = +2/3
Then the sum in those brackets:
-5/6 +2/3 = -5/6 +4/6 = -1/6
The absolute value changes the sign of this back to positive, so the value in square brackets is ...
3 -(1/6) = 18/6 -1/6 = 17/6
Finally, this value is divided by -17, so you have ...

First solve what is inside the parentheses (PEMDAS)
(5-21)+(-7+81)
(-16)+(74)
Add

Answer:
the factored form is -5x^2(7x-1)
Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m = 
= 
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
Hello!
- Diameter of the circle = 12 cm
Area of the Circle
A=πr²
Hey! We have the diameter, not the radius.
Don't panic. In order to find the radius, we should divide the diameter by 2.
So, the radius is 6.
Plug it into the formula:
A=π(6)²
A=π(36)
A≈113 cm
Hope it helps!
Good luck and enjoy your day!
