F(x)=x^2-3x+18 what is the value of discriminante of f?

- 63

Step-by-step explanation:

f(x) = 1x² - 3x + 18

a =1, b= -3, c=18

D= b² - 4ac = (-3)² - 4*1*18 = - 63

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
