The answer to this equation is 2
The rule for going 90 degree counter clockwise is:
(x, y) becomes (y, -x)
Therefore, the new points are:
A(-3, 1) to (1, 3)
B(-2, 2) to (2, 2)
C(-3, 4) to (4, 3)
Answer:
Step-by-step explanation:
Let John's age be x. This gives us that in 11 years, john's age will be 5 less than 5 times his current age. Therefore, we could get:
. This is your second equation. Solving for x, we get 4x=16 so x=4.
Answer:
x = - 12, x = 2
Step-by-step explanation:
Given
x² + 10x = 24
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(5)x + 25 = 24 + 25
(x + 5)² = 49 ( take the square root of both sides )
x + 5 = ± = ± 7 ( subtract 5 from both sides )
