Answer:
z = -1
Step-by-step explanation:
add like terms: 13z = -13
divide both sides by 13: z = -1
Answer:
The length of BC = 12
Step-by-step explanation:
c^2 = a^2 + b^2
15^2 = 9^2 + b^2
225 = 81 + b^2
b^2 = 225 - 81
b^2 = 144
b = 12
The length of BC is 12
Answer:
4 degrees.
Step-by-step explanation:
A complete circle has 360 degrees.
(4/360) of a circle = (4/360) * 360 degrees = 4 degrees
Nothing to "solve" here. Just graph this absolute value function.
Note that if x=2 we get y = -4. Thus, (2,-4) is the vertex. Plot this point.
Now, starting from (2, -4), draw a line at a 45 degree angle to the horizontal.
Then draw a corresponding line on the other side of the y-axis. You're done!
