<u>→ Chapter : Linear Equation of Two Variables ←</u>
<em><u>≡ We know that:</u></em>
↔ y = 4x + 6
⇔ 3x + y = 41
↔ y = 41 - 3x
<u><em>≡ Solution:</em></u>
<em>⇔ First, find the value of x:</em>
⇒ y = y
⇒ 4x + 6 = 41 - 3x
⇒ 4x + 3x = 41 - 6
⇒ 7x = 35
<u>⇒ x = 5</u>
<em>⇔ Then, find the value of y:</em>
⇒ y = 4x + 6
⇒ y = 4(5) + 6
⇒ y = 20 + 6
<u>⇒ y = 26</u>
<em>∴ So, the solution of that equation is (5, 26)</em>

Answer:
Step-by-step explanation:
Given that a person’s body surface area (BSA) (in meters squared) using the formula

We are to calculate the rate of change of BSA with respect to mass for a person of constant height h = 180 from m =70 to m =80
For this we calculate BSA for 80 kg and BSA for 70 kg first
Rate of change = 
=
i.e. rate of change per 10 kg is 0.129
No BSA does not increase more rapidly
F(1)=18
f(2)=18-2=16
f(3)=16-2=14
f(4)=14-2=12
f(5)=12-2=10
