-1 > (x + 4) / 2....multiply both sides by 2, eliminating the 2 on the right
2 * -1 > x + 4
-2 > x + 4 ....subtract 4 from both sides
-2 - 4 > x
-6 > x or x < -6
graphed : open circle (because there is no equal sign)...on -6, shading to the left
Answer:
The x intercepts are -2 ,4
Step-by-step explanation:
f(x)=(x-4)(x+2)
We set the function equal to 0 to determine the x intercepts
0 = (x-4)(x+2)
Using the zero product property
0 = x-4 0 = x+2
x=4 x=-2
The x intercepts are -2 ,4
Answer:
47.3 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
180 - 42.7 - 90 = N
N = 47.3 degrees
