To move a graph up c units, add c to the whole function
so basicaly what you did is you subtraced 3 from the whole function
the whole graph shifts 3 units down
B is answer
C = 15x + 50
let c be $125 since c represents the cost
15x + 50 = 125
15x = 125 - 50
15x = $75
x = 75 ÷ 15
x = 5
Answer:Length if tank=12m
Step-by-step explanation:
Dimension of tank is 12m by 8m by 5m
Which is length × breadth × heigh
Combine like terms, 1+6 is 7 and 2t+4t is 6t. so 6t+7=55. get the t by itself by subtracting 7 from both sides. 6t=48, divide by 6. t=8
