EXPLANATION
The parent square root function is

The translation

Will shift the graph of f(x) k units to left.
The translation

will shift the graph of f(x) to the right by k units.
Therefore if f(x) is shifted 4 units to the left its new equation is:

Answer:
Step-by-step explanation:

Answer:
Team B scored 17 points and team A scored 30 points.
Step-by-step explanation:
17 + 13 = 30
30 + 17 = 47
47 total points
Answer:
The formula is ⇒ 
Step-by-step explanation:
∵ The sequence is -1/2 , -3/10 , -9/50 , -27/250
∵ (-3/10) ÷ (-1/2) = 3/5
∵ (-9/50) ÷ (-3/10) = 3/5
∴ It is a geometric sequence
∴ The formula is Tn = ar^(n - 1)
Where a is the first term , r is the constant ratio between each two consecutive terms and n is the position of the number
∴ Tn = -1/2 ( 3/5)^(n - 1)
∴
Answer:
x=8 and y=21
Step-by-step explanation:
12x-28=7x+12 (the 2 angles are equivalent)
12x-7x=12+28
5x=40
x=8
9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))
9y-77+12*8-28=180
9y=180+28+77-96
9y=189
y=21
