Please help :/
soldi70 [24.7K]

Answer:

(a) $26.37 (b) $17.58

Step-by-step explanation:

The original price of a beach chair = $43.95

Janelle bought the chair on sale at = 60% off

The discount price = 60% of 43.95

                               = \frac{60}{100}\times 43.95

                               = 0.60 × 43.95

                               = $26.37

(a) The amount of discount = $26.37

(b) The sale price = 43.95 - 26.37 = $17.58

The amount of discount was $26.37 and the final sale price was $17.58.

54 - 54 + 9y = -18 + 54

9y = 36 isolate y

9y/9 = 36/9

If alpha beta are the roots of the equation
Vikki [24]

Answer:

Step-by-step explanation:

Hello, I believe that we can consider a different from 0.

By definition of the roots we can write.

ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }

Thank you
