Answer:
y =2
Step-by-step explanation:
Substitute -10 for x:
2(-10)-9y = -38
-20-9y = -38
-9y = -18
9y = 18
y = 2
In a quadratic function you square x so I'd assume that's what they want.
That means the values of f(x) would be:
9
1
1
9
25

Answer:
Simplifying
4u = 10.24
Solving
4u = 10.24
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Divide each side by '4'.
u = 2.56
Simplifying
u = 2.56
Step-by-step explanation:
The answer would be 18 units I believe
2(7+2)
2(9)
18 units
