A fraction is a piece of a whole 3/5
a opposite number is like -5 and +5
a reciprocal is the inverse operation -5 and +5 again
Answer:
1. Translate circle A using the rule (x − 3, y + 4).
4. Dilate circle A by a scale factor of 5
Step-by-step explanation:
we know that
All circles are similar figures
step 1
Translate the center of circle A to the center of circle B
we have
A(2,8) -----> B(5,4)
so
The rule of the translation is
(x,y) ----> (x+a,y+b)
(2,8) ----> (2+a,8+b)
2+a=5 ----> a=5-2=3
8+b=4 ---> b=4-8=-4
therefore
The rule of the translation is
(x,y) ----> (x+3,y-4)
step 2
Divide the radius of circle B to the radius of circle A to find out the scale factor
10/2=5
so
Multiply the radius of circle A by the scale factor to obtain the radius of circle B
therefore
Dilate circle A by a scale factor of 5
Answer:
No, the correct answer is 13/45
Step-by-step explanation:
Find the greatest common factor and change the equations
8/9 -> 40/45
3/5 -> 27/45
40/45 - 27/45 = 13/45
13/45 is the correct answer
Answer:
m=slope =5.5
Step-by-step explanation:
(2)
you may choce (c)
y-y1=m (x-x1)
(3)
y-30=5.5 (x-10)
y-30=5.5x-55
move 30 other side
y=5.5x-55+30
y=5.5x-25
