Answer:
x = - 
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
The radius of a unit circle is r = 1
substitute (x, - 
) into the equation and solve for x
x² + (- )² = 1²
x² + 
= 1 ( subtract from both sides )
x² = 1 - = 
( take square root of both sides )
x = ± 
= ±
since the point is in the 3rd quadrant then x < 0
x = -
23.8% of 164 is 39.032 so minus that off of 164 and you would've sold 124.968 cars and im guessing you should round so the dealership would've sold 125 cars.
Answer: 16x^2 - 9x + 11
Step-by-step explanation:
(5x^2+8x+18)+(11x^2-17x-7)
5x^2+8x+18+11x^2-17x-7
16x^2 - 9x + 11
Answer:
a < 4
Step-by-step explanation:
7 + a < 11
Subtract 7 from each side
7+a-7 <11-7
a < 4
