Ax^2 + bx + c = 0
x^2 + x + 2 = 0
a = 1
b = 1
c = 2
b^2 - 4ac
1^2 - 4(1)(2)
= 1 - 8
= -7
The value of the discriminant is -7.
Seventeen and fifty thousandths in stander form is this:
<em><u>17.05</u></em>
Answer:
18/100 or 9/50
Step-by-step explanation:
First, put 0.18 over 100 because there are 2 digits in the decimal, so you convert it to 18/100. Then, simplify it, and because the GCF is 2, divide the numerator and denominator. The final fraction ins 9/50.
The equation of a line is given by:
y - y1 = m ( x - x1 )
You are given m = -3
And the point (-2 , 4)
Sub these values into the equation,
y - 4 = -3 ( x - (-2))
y - 4 = -3 ( x + 2 )
y - 4 = -3x - 6
y = -3x - 2
Hope this helped! Ask me if there's any part of the working you don't understand :)
If the sales tax is 8%, then you multiply the previous cost by (1 + 0.08).
198.99 x (1.08) = 214.91.
Final Cost: $214.91.
