Answer:x=11
Step-by-step explanation:
2x-13=9
2x=9+13
2x=22
x=22/2
x=11
hope this helps :)
Answer:
C.
Step-by-step explanation:
First, isolate the y:
First, since there is no "equal to", we can ignore B and D since their lines are shaded.
Since the y is greater than, we need to pick the graph that is shaded above the line.
The answer is C as the shaded portion is above the graph and the graph is dotted.
Answer:
96 degrees
Step-by-step explanation:
The angle bisectors splits the two angles mentioned down the middle so the 2 angles are equal to each other.
4x + 4 = 2(x + 13) Distribute the 2
4x + 4 = 2x + 26 Subtract 2x from both sides
2x + 4 = 26 Subtract 4 from both sides
2x = 22 Divide both sides by 2
x = 11 Plug that back into either the right side or the left side of the original equation
4x + 4
4(11) + 4
44 + 4
48. Each angle is 48 degrees. 48 + 48 is 96
T² -1 =(t)² - (1)² = (t + 1) (t - 1)
