.................
Step-by-step explanation:
1. difference in algebraic expression is known SUBTRACTION
a² -b²=(a+b)(a-b)
see on "a" there is square and also on b
2. no there is no matter
now let multiply (a+b) (a-b)
a²+ab-ab-b²
a²-b²
now let multiply (a-b) (a+b)
a²+ab-ba-b²
ab and ba is same
a² -b²
Answer:
C). 9
Step-by-step explanation:
Given: f(x) = 8(x - 4) - 18
If f(x) = 22;
8(x - 4) - 18 = 22
8x - 32 - 18 = 22
8x - 50 = 22
8x = 22 + 50 = 72
x = 72 ÷ 8 = 9
Answer:
D) Only (-1,9) is a solution.
Step-by-step explanation:
x+y =8
x^2 + y = 10
Lets check the first point (-1,9)
Put in x =-1 y =9
x+y =8
-1+9 = 8
8 =8
This works
x^2 + y = 10
(-1)^2 +9 =10
1+9 = 10
10 = 10
This works
Lets check the second point (-2,6)
Put in x =-2 y =6
x+y =8
-2+6 = 8
4=8
This does not work
We can stop now. (-2,6) cannot be a solution
