Consider the function y = f (x), the element 'x' is the input of the function, and 'y' is the value of the function or the output.
Now, we have to determine the equation for " Nine times the input minus seven is equal to the output"
Since, the input of the function refers to the variable 'x' and output of the function refers to the variable 'y'.
The required equation is:

So, 
Therefore, 9x-7=y is the required equation.
Therefore, Option C is the correct answer.
So 60 by 80,
60 <80 so 60=width
she moves it so that width=300
findn height
60:300=80:x
60/300=80/x
muliplyb oth sides by x
60x/300=80
x/5=80
mulitpliy both sides by 5
x=400
the height=400 mm
Answer:
She will have $25.91 left in her wallet
So 1/4 of 12 is
'of' can be translated to multiply so
1/4 times 12=12/4=3
she used 3 eggs
B is the answer
Answer:
A.) 126°
Step-by-step explanation:
180-54=126
A straight line equals 180°
So you can subtract 180° by the known angle to find the unknown angle.
