For this case what we must do is to use the formula of the resolvent in the following way:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Where,
a = 1
b = -4
c = -38
Substituting the values:
x = (- (- 4) +/- root ((- 4) ^ 2 - 4 * 1 * (- 38))) / (2 * 1)
x = (4 +/- root (168)) / 2
x = (2 +/- root (42))
Answer:
x = 2 +/- squareroot 42
Answer: C. 5/6
Steps:
Use the formula x1-x2/y1-y2 to find the slope
(5,11), (-5,-1)
-5-5/-1-11
= -10/-12
=5/6
Answer:
Akira = 22 + 30x
Jen = 53 + 20x
for both of them to have sold the same number of tickets, the number of days for them to be able to sell the same amount is 3.1 days
Step-by-step explanation:
Standard form of a line is Y=mX+b
where m is slope
4x+2y=-6
2y=-4x-6
y=- 2x - 6
m= - 2 and y intercept is b=-6
