Answer: Rita and Tina's total weekly wages can be represented as 11r + 32 + 11t or 11( r + t ) + 32
Step-by-step explanation:
Since, For Rita,
Charges per hour = $ 11
Working time = r hours,
Overtime charges for a week = $ 32,
Thus, her weekly charges = 11 r + 32
Now, For Tina,
Charges per hour = $ 11
Working time = t hours,
Thus, her weekly charges = 11 t
Hence, the combined weekly wages of both Rita and Tina = 11 r + 32 + 11 t
= 11( r + t ) + 32
Which is the required expression.
Refrection of a function across the y-axis, changes the sign of x in the function.
Thus, given the function:

Refrection of the function across the y-axis will result in the function:

Refrecting a function across the x-axis, changes the sign of the function.
Thus, refrecting the function:

across the x-axis will result in the function:

Answer:
fjdpaohgw] -9fmU
Step-by-step explanation:
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
