Answer:
x = -5/7
Step-by-step explanation:
8 1
---------- = ----------
x+3 x+1
Using cross products
8 (x+1) = 1 (x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x-x+3
7x+8 =3
Subtract 8 from each side
7x +8-8 =3-8
7x = -5
Divide each side by 7
7x/7 = -5/7
x = -5/7

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
