Answer:
(A) y - x
Step-by-step explanation:
Finding a:
- ax + x² = y² - ay
- ax + ay = y² - x²
- a(x+y)= (y+x)(y-x)
- a = y - x
Correct choice is (A)
As you may know, this means that 3p-6 is equal to 90 degrees. Set up an equation:
3p-6 = 90
3p = 96
p = 32
no 28
solution
(AB)=100
ABC+CBD=100
4x+2+3x-7=100
7x-5=100
7x=100+5
x=105/7
x=15
(CBD) =3x-7
3(15)-7
45-7
38
Step-by-step explanation:
by using above information
Use substitution
x -4x - 7 = 2
-3x = 9, x = -3
Y = -4(-3) - 7
Y = 12 - 7, y = 5
Solution: x = -3, y = 5
