Answer:
2
Step-by-step explanation:
Discriminant of a quadratic equation can be calculated as:
Discriminant = b² - 4ac
b = coefficient of x term = 2
a = coefficient of squared term = 1
c = constant = 7
So,
Discriminant = 4 - 4(1)(7) = -24
So, the correct answer to this question is option C
Answer:
C= 30

Answer:
8931
Step-by-step explanation:
1 1 1
21 x 18 x 13 = 4914
16 x (18x13) = 3744
13 x 21 = 273

(I am not 100% Sure, you should double check)
11) x-intercept: 12
y-intercept: 8
12) x-intercept: -18
y-intercept:-16
13) x-intercept: 6
y-intercept:10
Sorry I can't graph it for you but here are the equations in the slope-intercept form
11)y=-2/3x+8
12)y=-8/9x-16
13)y=-5/3x+10
