Step-by-step explanation:
To find the roots of the equation, factor the equation and set each factor equal to 0 or use the quadratic equations. The quadratic expression does not factor and must be solved using the quadratic formula.
where a = 1, b=-3, and c=1
Answer:
He add $5 more each month
Step-by-step explanation:
* Lets consider this problem as an arithmetic sequence because
he add every month x dollars more
∵ He start with 50 dollars ⇒ a (1st amount)
∵ He add x dollars every month ⇒ d
∵ He did that for 36 months ⇒ n
∵ He saved 4950 dollars ⇒ Sn
∵ Sn = n/2[2a + (n - 1)d]
* Where Sn is the total money after <em>n</em> months
<em>a</em> is the first amount he saved
<em>d</em> is the money he add more each month
∴ 4950 = 36/2[2(50) + (36 - 1)(x)]
∴ 4950 = 18[100 + 35x]
∴ 4950/18 = 100 + 35x
∴ 35x = 275 - 100 = 175
∴ x = 175/35 = 5 dollars
$9147 x 12 =190,764
12 is how many months there is in a year
The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints. The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.
x-coordinate of midpoint: (-4 + 0)/2 = -4/2 = -2
y-coordinate of midpoint: (9 + 7)/2 = 16/2 = 8
Answer: The midpoint is (-2, 8).
