Answer:
A.make calculation easier
Answer:
-2-(-16)=14
Step-by-step explanation:
Use KCC rule
35 + 0.05m > 50 + 0.01m
0.05m > 15 + 0.01m
0.04m > 15
m > 15 x 25
m > 375
You must send more than 375 messages.
Reflecting over the x axis means to perform the following tranformation:

So, you maintain the x coordinate, and change the sign of the y coordinate. The vertices become

Translating 3 units to the left means to perform the following transformation:

So, you maintain the y coordinate, and decrease the x coordinate by 3. The vertices become

So, as you can see, after these two transformation, the vertices A, B and C become A', B' and C'.
Answer:
A) y=x+1
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(9-5)/(8-4)=4/4=1
y-5=1(x-4)
y-5=x-4
y=x-4+5
y=x+1
