According to the properties of the quadratic equation the sum of its roots is '-b', in other words x₁+x₂= -b
Answer: -b
Since this is a compound interest, we will use this formula: A = P(1+r/n)^n*t
P = $1000 --> the amount that we start with
r = 8% --> this is the rate
n = 4 --> This is because it is compounded quarterly.
t = 5 --> the amount of years
A = 1,000.00(1 + 0.02)^(20)
So our final value after inserting those numbers in the equation is: $1,485.95.
Answer:
(0,3)
y=3
x=0
Step-by-step explanation:
x+5y=15
-3x+2y=6
solve the equation
x=15-5y
-3x+2y=6
substitute the value of x into an equation
-3(15-5y)+2y=6
distribute
-45-15y+2y=6
add 15 to 2
-45-17y=6
add 45 from both sides
17y=51
divide both sides by 17
y=3
substitute the value of y into an equation
x=15-5•3
multiply 5 to 3
x=15-15
subtract
x=0
(0,3)
Step-by-step explanation:
The 2 lines are parallel to each other which means that angle #5 and 93° are alternate interior angles so by definition, they are equal. Hence angle 5 = 93°
