While at the beach Daniel buys lunch for his family from a food stand he purchased one hotdog for $2.50 and three hamburgers if
Alex17521 [72]

The cost of each hamburger is $ 3.5

<em><u>Solution:</u></em>

Given that, Daniel purchased one hotdog for $2.50 and three hamburgers

He spent $ 13 in total

Let "H" be the cost of each hamburger

From given,

one hotdog for $2.50 + three hamburgers each for "H" = $ 13

Thus we get,

1 \times 2.50 + 3 \times H = 13\\\\2.50 + 3H = 13\\\\\text{Solve the above equation for H}\\\\3H = 13 - 2.50\\\\3H = 10.5\\\\\text{Divide both sides of equation by 3}\\\\H = 3.5

Thus cost of each hamburger is $ 3.5

1. Evaluate the discriminant for each equation, then use it to determine the nature of the roots for each quadratic equation.
Marizza181 [45]

Given the quadratic equation ax^2 + bx + c = 0, the coefficients of x^2, x and 1 are a, b and c respectively.  

(a) and (b) are not valid quadratics, because they omit the exponent 2.   Rewrite these as comments within your original post, please.

(c) 4x^2+20x+25=0:  Here, a = 4, b = 20 and c = 25.
