-5x-3=-23
Add 3 to both sides
-5x=-20
Divide both sides by -5
x=4
Final answer: x=4
Check:
-5(4)-3
-20-3
-23
-23=-23
True
Since these 2 events are independent , the probability of them both occurring is obtained by multiplying them
P(rain on Wed and Sat) =0.30* 0.60 = 0.18
which is 18%
F is 5 because -1 and 1 are not web that makes 8 odd so f is 5
Definitely multiply out the given factors:
f(x) = 10 + 2x - 5x - x^2, or f(x) = -x^2 - 3x + 10
Find the derivative: f '(x) = -2x - 3
Set the deriv. = to 0 and solve for x: -2x = 3, and x = -3/2
This x = -3/2 is the x-coordinate of the max value. The y-coord. is
f(-3/2) = (-3/2)^2 - 3(-3/2) + 10 = 21.25
I realize that this result does not agree with any of the four possible answers. Please ensure that y ou have copied down this problem completely and correctly.
Answer:
Step-by-step explanation:
ok so y= 7-2x just need to move 2x to the other side
