Answer:
Third graph down
Step-by-step explanation:
2x -6 ≥ 6(x-2)+8
Distribute
2x - 6≥6x -12+8
Combine like terms
2x - 6≥6x -4
Subtract 2x from each side
2x-6-2x ≥6x-2x-4
-6 ≥4x-12
Add 4 to each side
-6+4 ≥4x-4+4
-2 ≥4x
Divide by 4
-2/4 ≥4x/4
-1/2≥x
Closed circle at -1/2
Line going the the left
Answer:
slope should be 1.50x and your y-intercept should be 7.50
Step-by-step explanation:
Answer:
60! hope this helps!
Step-by-step explanation:
We can write this as:-
P(x) = + x^3 - 5x^2 - 25x + 125
There are 2 changes of real sign so by Descartes Rule of signs there are either 2 positive real roots or 0 positive roots.
P(-x) = - x^3 - 5x^2 + 25x + 125
There is just one change of sign so there is exactly 1 real negative root.
125 is a multiple of 5 so By rational root theorem 5 could be a positive root.
P(5) = 125 - 125 - 125 + 125 = 0 so one zero is 5
if we divide the polynomial by (x - 5) we get the quadratic
x^2 - 25
(x + 5)(x - 5) = 0
x = 5,-5
so the roots are 5 (multiplicity 2) and -5.
2 real positive zeroes and one real negative zero
Reason 1: Given.
Reason 2: Vertical angles
Reason 3: Angle, Side, Angle(ASA)
