Answer:
The independent variable is s
The dependent variable is c
Step-by-step explanation:
Identify the independent and dependent variables:
The equation c = 0.09s gives the amount c (in dollars) of commission a salesperson receives for making a sale of s dollars.
c = 0.09s
Where
c = commission the salesperson makes
s = amount of sales
The variables in the equation are c and s
The independent variable is s
The dependent variable is c because it's value is determined by the amount of sales of the salesperson
Answer:
11x+2=
Step-by-step explanation:
Simply combine the like terms. Since 9 and -7 are like terms you can combine them, 9-7=2
We know that 1 mm=0.01 dm
75 mm=0.75 dm
choice D
Answer:
8x - 3y = 12 _______( 1 )
5x = 2y + 7 _______( 2 )
On further solving ( 2 ), we get
5x - 2y = 7 _______( 3 )
Multiply ( 1 ) by 2
16x - 6y = 24 _______( 4 )
Multiply ( 3 ) by 3
15x - 6y = 21 _________( 5 )
Subtract ( 4 ) and ( 5 )
( 16x - 6y ) - ( 15x - 6y ) = 24 - 21
16x - 6y - 15x + 6y = 3
Put this in ( 2 )
5 ( 3 ) = 2y + 7
15 = 2y + 7
2y = 15 - 7
2y = 8
y = 8 / 2
