Answer:
this is from a angle I think you want to write perimeter and area of this ×+1= and you want see that
Answer:
z = 5/2y -1
Step-by-step explanation:
We observe that z has ...
- 1 added
- the sum multiplied by 2/5
To solve for z, we undo these operations in reverse order.

∂t/∂x = -46x/(8 +x² +y²)²
∂t/∂y = -46y/(8 +x² +y²)²
At (x, y) = (1, 1)
.. ∂t/∂x = -46/100
.. ∂t/∂y = -46/100
Your formula is right but you must have plugged it in wrong.
Y= 1/10 x
X is your distance, so plug in 85 with x
Y= 1/10 85
One- tenth as a decimal equals 0.1. So 0.1 times 85 will equal 8.5
