Answer:
x = 1
Step-by-step explanation:
Given in the question the equation
y = -x² + 2x - 1
To find the x-intercept, substitute in 0 for y
0 = -x² + 2x - 1
To find value of x use quadratic equation
x = -b ± √b²-4ac / 2a
here a = -1
b = 2
c = -1
x1 = -2 + √2²-4(-1)(-1) / 2(-1)
= -2 + 0 / -2
= -2 / -2
= 1
x2 = -2 - √2²-4(-1)(-1) / 2(-1)
= -2 - 0 / -2
= -2 / -2
= 1
Answer:
$2,651
Step-by-step explanation:
The first step is to find what 1.5% of $2,600 is.
Secondly, divide 2600 / 100 = 26
Finally, multiply 26 by 1.5 = 39.
Add 39 and 12 to 2600 = $2,651.00 total earnings for the month.
