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
A = LW......W = A/L
A = 5/8
L = 10
W = (5/8) / 10
W = 5/8 * 1/10
W = 5/80 = 1/16
Answer:
whats the question
Step-by-step explanation:
?
To figure out the answer here, all you have to do is plug the given point into your equations and see if the result is true:
(4, 2) .... aka (x, y)
2 - 4 = 2
-2 = 2 ... this one is FALSE, as -2 doesn't equal 2, so already you can tell that the point won't be a solution, but still, check the second equation.
-3(4) - 2(2) = -8
-12 - 4 = -8
-16 = -8 .... this one is also false. (4, 2) is not a solution for this system of equations.
Answer:
y-3=4(x-10)
Step-by-step explanation:
Point Slope Form: y-y1=m(x-x1)
Where m=slope and (x1, y1) is a point on the line.
m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4
So the slope is 4,
y-3=4(x-10)
