Answer:
The images are;
A’ (5,2) B’ (2,1) and C’ (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over x-axis, we get (x,-y)
So;
A ( 2,5) becomes (2,-5)
B (1,2) becomes (1,-2)
C ( 3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees counterclockwise about the origin
Here we have;
(x,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)
Answer:
x = 0.5
Step-by-step explanation:
9/50 + 12x/50 = 15/50
9 + 12x = 15
x = 6/12 = 0.5
Answer:
The 2nd and last one
Step-by-step explanation:
Answer:
Step-by-step explanation:
8
Let a and c be the number of adult and children tickets sold respectively.
a=2c
6.2c+9.8a=593.4, using a from above in this equation gives you:
6.2c+9.8(2c)=593.4 perform indicated multiplication on left side
6.2c+19.6c=593.4 combine like terms on left side
25.8c=593.4 divide both sides by 25.8
c=23
So 23 child tickers were sold that day.
