Question

I really need help with algebra 1!! Systolic blood pressure, the higher number in a blood pressure reading, is measured as your heart muscle contracts. The inequality P ≤ ½a + 110 gives the normal systolic blood pressure, P, based on age, a, (in years).
Find the systolic blood pressure for a 16 year old.
At age , 30 does 125 represent a maximum or minimum systolic pressure?
Explain:

Answer 7

ok

Answer 8

Have you tried substituting those specific ages into your inequality?

Answer 9

no, i dont know how :/

Answer 10

Well, the information tells you that a stands for the age, then in part A, they give you an age of 16
so plug 16 in for a
\[P \le \frac{ 1 }{ 2 }a+110 \rightarrow P \le \frac{ 1 }{ 2 }16+110\]

Answer 11

oh! okay im going to try that
