Solution:
3x - 5 = -2x²
2x² + 3x - 5 = 0
By splitting the middle term,
2x² - 2x + 5x - 5 = 0
2x (x - 1) + 5 (x - 1) = 0
(2x + 5)(x - 1) = 0
So, 2x + 5 = 0
x = -5/2
(OR)
x - 1 = 0
x = 1
The roots of 2x² + 3x - 5 = 0 are: A. x = 1 & B. x = -5/2
60/30 as a mixed # is 2/1 or 2
No, the sequence is algebraic.
Answer:
Each highlighter is $1.30
Step-by-step explanation:
First the formula is 10+4h=15.20. H represents the unknown cost of each highlighters. Solve for h by subtracting 10 on both sides. 4h=15.20 Then divide 4 on both sides to get h by itself. h=1.30 Therefore one highlighter would cost $1.30
