Answer:
2
Step-by-step explanation:
-1-(-3) is the same as -1+3, which is 2
you can also rewrite it as 3-1, which is also 2
Answer:
a) -4
b) 2
Step-by-step explanation:
a) f(-2) = 3*-2 + 2 = -4
b) f(x) = 8
3x + 2 = 8
3x = 8 -2
3x = 6
x = 6/3
x = 2
Answer:
±square root 20
Step-by-step explanation:
x²= 20
x= square root 20
x= 2 square root 5
x≈ 4.4721
If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x.
so 3/4 = 1/4x
3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3)
so 4 x ? = 1.33. 1.33 / 4 = 0.3325
so (if you're solving for x) I believe the answer is x = 0.3325
