Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ± 
( add 3 to both sides )
x = 3 ±
Then
x = 3 - ≈ - 6.49 ( to the nearest hundredth )
x = 3 + ≈ 12.49 ( to the nearest hundredth )

According to wikihow its letter c
Answer: b=y+3/x
Step-by-step explanation:
bx-3=y
bx-3+3=y+3
bx=y+3
bx/x=y+3/x
Answer:
C
Step-by-step explanation:
7x + 3y = 30 (equation 1)
-2x + 3y = 3 (equation 2)
9x = 27 (subtract the two equations to eliminate y)
x = 3 (divide by 9)
7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)
21 + 3y = 30 (7 * 3 = 21)
3y = 9 (Subtract 21)
y = 3 (divide by 3)
Answer is (3, 3)
