Answer:

Step-by-step explanation:

let price of  one pretzel=x

price of one soda=y

3x+4y=11.25   ...(1)

5x+2y=8.25    ...(2)

multiply by 2

10x+4y=16.50   ...(3)

(3)-(1) gives

7x=5.25

x=0.75

from (1)

3(0.75)+4y=11.25

2.25+4y=11.25

4y=11.25-2.25

4y=9

y=9/4=2.25

cost of one pretzel=$0.75

cost of one soda=$2.25

Solve the equation x^2 + 5x = -1 by completing the square.
8090 [49]

Answer:

The answer to your question is: the third option

Step-by-step explanation:

              x² + 5x = - 1

              x² + 5x + (\frac{5}{2}) ^{2} = -1  + (\frac{5}{2} )^{2}

             (x + \frac{5}{2})² =   - 1 + 25/4

            (x + \frac{5}{2})²  =  (-4 + 25) / 4

            (x + \frac{5}{2})² = 21/4

            (x + \frac{5}{2}) = ± \sqrt{\frac{21}{4} }

            x = \frac{5}{2} ±   \frac{\sqrt{21}}{2}

            x = \frac{-5 ± \sqrt{21} }{2}
