Answer:
17.5
Step-by-step explanation:
17×4=68; half of 4 is 2; 68+2=70
When reflecting across the Y axis, the Y values remain the same.
Now if you were reflecting across Y = 0, the x values would just be inverse ( opposite signs).
So this triangle if reflected across Y = 0 the new vertices would be (4,4) (2,3) and (5,2)
Now since the reflection line is y = -1, which is a one unit shift to the left of y = 0, subtract 1 unit from each X value.
The locations are now: A'(3,4), B'(1,3) and C'(4,2)
One angle has 60 degrees, the other angle has 30 degrees.
60 divided by 30 = 2.
and 60 + 30 = 90.
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
