Answer:
x divided by 75% = y
Step-by-step explanation:
Given that the ski club sold 42 Italian hoagies and 53 roast beef hoagies, they sold a total of 95 hoagies. The ratio of Italian hoagies to total number of hoagies sold is obtain by dividing 42 by 95. Mathematically,
ratio = 42 / 95
Answer:
The discrimant of this equation is 144.
Step-by-step explanation:
First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :
9x² + 14x + 13 = 8x²
9x² + 14x + 13 - 8x² = 8x² - 8x²
x² + 14x + 13 = 0
It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :
x² + 14x + 13 = 0
D = b² - 4ac
= 14² - 4(1)(13)
= 196 - 52
= 144
