Step-by-step explanation:
|4x + 8| > 2
Therefore 4x + 8 > 2 or 4x + 8 < -2.
When 4x + 8 > 2, 4x > -6, x > -1.5.
When 4x + 8 < -2, 4x < -10, x < -2.5.
Hence, x < -2.5 or x > -1.5.
Answer:
D) x=5, x=-5.
Step-by-step explanation:
x^2-25=0
factor
(x+5)(x-5)=0
x+5=0, x-5=0,
x=0-5=-5,
x=0+5=5.
Answer:
A
Step-by-step explanation:
The line cuts the y at positive two. The rise over run of the slope is -3/1, or 3.
Just had a test on these kinds of problems and i got 100.
Step-by-step explanation:
For every increase in the x-value by 1,
the y-value decreases by -2.
(From 3 to 1 and from 1 to -1)
Hence, slope of line k
= Rise/Run = (-2)/1 = -2. (A)
