Answer:. x = 18
Step-by-step explanation:
Solve by substitution. Given: y= 12x. Rewrite the original equation y= 180 + 2x to 12x = 180 +2x. Subtract 2x from both sides. 10x = 180. Then divide both sides by 10.
x=18
So once she has sold 18 necklaces, she has covered her costs (180 + 36) and she begins to make a profit.
Answer:
16 inches
Step-by-step explanation:
c = πd
50.26 = 3.14 * d
Divide both sides by 3.14
d = 16.0
16 inches
Answer:
1
Step-by-step explanation:
To find the solutions (or, in other words, zeroes) of a quadratic function/equation we use the discriminant (the part that's inside the square root of the quadratic formula, 
.)
If the discriminant is smaller than 0, there are no zeroes
If the discriminant is equal to 0, there is one zero
If the discriminant is larger than 0, it has two zeroes
The discriminant is commonly denoted as 
.
b = -0.5 and a = 1. 2=3+-1. 1 to the third power is just 1, times 8 is 8. -0.5 to the third power is -0.125. -0.125 times 8 is -1. 8 - (-1) is 9. 36 times 1 is 36, times -0.5 is -18. 9-(-18) = 27. I hope this helps! Could I possibly get brainliest?
