Joan: 12 years old
Amber: 22 years old
If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)
Answer:
x² - 6x = -5
x = {1, 5}
Step-by-step explanation:
The square of a number minus six times a number equals negative five.
x² - 6x = -5
Add 5 to both sides
x² - 6x + 5 = 0
Factor
(x - 1)(x - 5) = 0
x = {1, 5}
Answer is (9, 7)
Step by step
Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).
This means, we switch x and y and make x negative.
So
(-7, 9) ➡️ ( 9, 7)
Are you asking to simplify all of those equations?
