Answer:
f (3) is equal to 31
Step-by-step explanation:
f (3) means that x is equal to 3 [hence f (x) ---> f (3)]
Plugin 3 into all the x values to solve:
4(3)^2 - 2(3) + 1
4(9) - 6 + 1
36 - 6 + 1
30 + 1
31
f (3) is equal to 31
Total people x,
then, 3.5x + 5.5x + 6 = 51
simplify, 9x +6 = 51
subtract 6 on both sides, 9x= 45
divide by 9 on both sides, x= 5
therefore, total 5 people in the family.
Answer:
2x - 2y
Step-by-step explanation:
Multiply by 1
combine like terms
Combine the second
rearrange terms
Then you should come up with the sloution 2x - 2y
You have to insert 67 for y and then only solve the equation for X
67=-24x+379
x=?
