C. No, the graph fails the vertical line test. I believe that is the answer.
Answer:
-4 or -3
Step-by-step explanation:
Calculate the determinant:
D = b^2 - 4ac = 49 - 48 = 1
Apply the formula:
x = (-b +- sqrt(D))/2a = (-7 +- 1)/2 = -4 or -3
Answer:
9=0.6q where q is the number of questions on the exam.
Step-by-step explanation:
X/6 >= 9
x >= 6 x 9
x >= 54
Therefore, 60, 72 and 54 satisfies the inequality.
