Quadratic equation solve using formula​
kiruha [24]

Answer:

2 , 1\2

Step-by-step explanation:

b² - 4ac = (-5)² - 4*2*2

             = 25 - 16

             = 9

\sqrt{b^{2}-4ac} = \sqrt{9} = \sqrt{3*3}=3

x= \dfrac{-[-5] + 3}{2*2} ;  x = \dfrac{-[-5]-3}{2*2}\\\\x =\dfrac{5+3}{4} ; x = \dfrac{5-3}{4}\\\\x=\dfrac{8}{4}  ;x = \dfrac{2}{4}\\x = 2 ; x = \dfrac{1}{2}

A gym membership is $100 sign-up fee and charges $20 a month thereafter. How much is the membership fee in a month?
trapecia [35]

Answer:

$120

Step-by-step explanation:

y = mx + b

The $100 sign up fee is a set amount, or the b value.

The $20 would be the m value since it the constant change, or the slope.

Thus, the equation would be y=20x + 100

The membership fee for 1 month would be --->

y= 20(1) +100

y= 20 + 100

y= $120
