Any negative number added to a positive number always brings you further to the left, which is considered the negative zone. It's more like subtracting in a different way. That said, let's make the equation.
<em> </em>
Now, multiply 3 by 8.

Add negative 4, meaning subtract 4 in a dynamic way.

Answer:
Photosynthesis depends on the carbon dioxide released during cellular respiration.
Step-by-step explanation:
The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31
The function is given as:

When the normal systolic pressure is 125, it means that:

So, we have:

Subtract 125 from both sides of the equation


Rewrite the equation as:

Using a graphing calculator, we have:

But age cannot be negative.
So, we have:

Approximate

Hence, the age of the woman is 31
