Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
You have to convert the percent into a decimal before you convert it into a fraction then you simplify the fraction.

Answer:
down
Step-by-step explanation:
y = -3x^2 +x +1
The coefficient of the x^2 term is negative so it opens facing down
X^2 coeffient
- means down
+ mean up
5.94/3= 1.98
Each loaf of bread cost $1.98.
