Answer:
68
Step-by-step explanation:
15% of 80 is 12 so you subtract 12 from 80 and thats 68.
Answer:
140/20
Step-by-step explanation:
If you reduce the fraction your left with just 7
Answer:
B
Step-by-step explanation:
(f+g)(x)=f(x)+g(x)
3x+1+x2-6 = x2+3x-5
the solution is here,
the coordinate of centre of circle A is (3,2)
and the coordinate of centre of circle B is (3,0).
so the translation point from A to B is (3-0,0-2)=(3,-2).
Now the translation rule is given by (x+h,y+k)
where h is the tranalation anlong the x-axis and k is the translation along the y-axis.
For this problem, translation ruleis (x+3,y-2).
Then, radius of circle A(r1)=2 units
radius of circle B (r2)= 3 units
as the circle A is translated to B, the scale factor is
r2/r1=3/2=1.5
In conclusion, the translation rule for given circles is (x+3,y-2) and its scale factor is 1.5
