Reflecting over the y axis means the x would change (flip from either positive to negative) so therefore the answer is A.
Answer:
4^4=4^3*4=64*4=256

Answer:
Step-by-step explanation:
The diameter is twice the radius, so ...
XY = 2·ZY
12x -4 = 2(3x +4) . . . . substitute the given expressions
12x -4 = 6x +8 . . . . . . eliminate parentheses
6x = 12 . . . . . . . . . . . . add 4-6x
x = 2
YZ = 3x+4 = 3(2) +4
YZ = 10
Answer:
y=2x-58
Explanation:
In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)
This gives us:
y=2x + c
Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:
2=2(30) + c
2=60+c
2-60=c
-58=c
So now we know that our C (constant) is - 58.
Hence our point-slope formula is:
y=2x-58
Which you can test with the other point:
-28=2(15) - 58
