Answer:
The value of b² - 4 a c = 100
Step-by-step explanation:
Given equation x(x + 8) = 9
⇒ x² + 8 x = 9
⇒ x² + 8 x - 9 =0
The standard form of quadratic equation
a x ² + b x + c
Here a = 1 , b = 8 , c = -9
<em> The value of b² - 4 a c = ( 8)² - 4 (1)(-9) </em>
= 64 + 36
= 100
<u><em>Final answer:-</em></u>
The value of b² - 4 a c = 100
Answer:
B The number of candles Sallie sells
Step-by-step explanation:
Given the equation :
y = 8x
y = amount earned ; x = number of candles sold
Cost per candle = 8
The Independent variable is the number of candles sallie sells as it is this variable which determines the amount which sallie will earn from candle sales (dependent variable). In essence, the variable which determines or affects the dependent variable is the independent variable.
Answer:
L=193
Step-by-step explanation:
Initial length of the road =57mi
L= Total length
D=number of days worked
Number of miles added in 1 day= 4mi
Therefore,
L=57+D*4
After 34 days,
L=57+(34*4)
L=193mi
