Is the leading coefficient of the function positive or negative?

Negative.

Step-by-step explanation:

To understand the question, you first must understand the slopes of different types of equations.

A linear equation: will travel from the third quadrant to the first.

If you plug in 2 for x, y will equal 4. Both values are positive, leading to a positive correlation.

A linear equation: will face the other direction, as shown in your attached image. When you plug in a positive number for x, like 5, y will equal -15, making the graph go up and left towards negative values.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
