Answer:

$z=6$

Step-by-step explanation:

$-2.8\left(z+1\right)-\left(3.5z-9\right)=-31.6$

$-6.3z+6.2=-31.6$

$-6.3z+6.2-6.2=-31.6-6.2$

$-6.3z=-37.8$

$\frac{-6.3z}{-6.3}=\frac{-37.8}{-6.3}$

$z=6$

Step-by-step explanation:

Step 1: Define

Point (-5, 6) → x₁ = -5, y₁ = 6

Point (3, 2) → x₂ = 3, y₂ = 2

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formulas]: $\displaystyle d = \sqrt{(3+5)^2+(2-6)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(8)^2+(-4)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{64+16}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{80}$
[Distance] [√Radical] Simplify: $\displaystyle d = 4\sqrt{5}$
