Answer:
x = 4
Step-by-step explanation:
a = i-2j
b = 2i-xj
1 = k•2
-2 = k•(-x)
=> 1/2 = k
=> (-2)/(-x) = k
=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4
Answer:
It is -7x + 5
Step-by-step explanation:
I could do a whole explanation, but I'm sure you want the answer quickly. So there ya go. Hope this helps!
The answer would be J because if the equation was transferred into a positive then it would be 2y and 5x marking 5x on the bottom and 2y vertically.
Hope this helps!!
So when you have one of these, it’s just asking you so solve it as if x were 6 (as you see where the x in f(x) is replaced with a 6.
so you’d sub x for 6
giving you:
4 x (6)
which = 24
hope that makes sense :)
