Answer:
x =14
Step-by-step explanation:
14x+24=18x-32
Subtract 14x from each side
14x-14x+24=18x-14x-32
24 = 4x -32
Add 32 from each side
24+32=4x-32+32
56 = 4x
Divide each side by 4
56/4 = 4x/4
14=x
Answer:
50
Step-by-step explanation:
The total salary was $3650.
The base salary is $3500.
$3650 - $3500 = $150
He made $150 in commission.
He makes $12 commission for every $100 he sells.
$150/$12 = 12.5
He sold 12.5 amounts of $100.
Each $100 corresponds to 4 cases.
12.5 × 4 = 50
He sold 50 cases of coffee.
Answer:
See below
Step-by-step explanation:
Domain: set of x values
Range: set of y values
Function: no two x values are the same
Line 1:
Domain: {3, 4, 5}
Range: {1, 2, 3, 4}
Function: no since there are two points with x-coordinate 3
Line 2:
Domain: {-1, -2, 1, 2}
Range: {1, 3}
Function: yes since all x-coordinates are different
Line 3:
Domain: {-2, -1, 0, 1, 2}
Range: {0, 1, 4}
Function: yes since all x-coordinates are different
