Answer:
5x+10
Step-by-step explanation:
let f(x)=(x-10)/5=y
now write 'x' in term of y
i.e, x-10=5y
i.e, x=5y+10
now replace y with x to get required inverse of f(x)
=5x+10
Answer:
3. y = 3/2x -1 4.y = 2x - 3
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
10 take away 2 is 8.
Answer:
using the first two equations cancelling the z
-2x-2y-5z=-7
6x+8y+5z=9
4x +6y= 2
using the second and the third equations cancelling the z
6x+8y+5z= 9
-2x-3y-5z= -6
4x +5y = 3
4x + 6y = 2
-4x -5y = -3
y= -1
2x + 2(-1) + 5z = 7
2x - 2 + 5z = 7
2x + 5z = 9
6x + 8(-1) + 5z = 9
6x - 8 + 5z = 9
6x + 5z = 17
-2x - 5z= -9
4x = 8
x = 2
2(2) + 2(-1) + 5z= 7
4 - 2 + 5z = 7
2 + 5z = 7
5z = 5
z = 1
(2, -1, 1)
the answer is a.
