Answer:
RST = 20
Step-by-step explanation:
a ray that divides an angle into two equal angles is called an angle bisector.
So RSP = PST
3 x -2 = 9x - 26
6x = 24
x = 4
RST = 3x -2 + 9x -26 = 20
Answer:
x < - 6 or x > 6
Step-by-step explanation:
Inequalities of the type | x | > a, always have solutions in the form
x < - a or x > a
given 4| x + 2 | > 16 ( divide both sides by 4 )
| x + 2 | > 4 ← in the above form, hence
x + 2 < - 4 or x + 2 > 4 ( subtract 2 from both sides of both inequalities )
x < - 6 or x > 6 ← solution
Answer:
C
Step-by-step explanation:
If you fill in x=0, you are left with the y intercept. In the picture you can see it must be larger than y=10. This invalidates answer A and D.
The x-coordinate top of the parabola ax²+bx+c=0 is given by y = -b/2a, so immediately we can see -b has to be positive. This leads you to answer C because -9x implies b=-9, and --9 is positive.
