Answer:
y=1/3x-6
Step-by-step explanation:
x-3y=18
3y=x-18

Answer:
The area of a trench is 5.5 m² .
Step-by-step explanation:
Formula
Area of a rectangle = Length × Breadth
As given
Tanya has a garden with a trench around it.

i.e

Put in the above formula

= 5 m²
As given

i.e



= 10.5 m²
Area of the trench = Area of garden with trench - Area of garden
Put the value in the above
Area of the trench = 10.5 m² - 5 m²
= 5.5 m ²
Therefore the area of a trench is 5.5 m² .
Answer:
Step-by-step explanation:
g(x)=ax²+3x-5
then g(-1)=-15
therefore g(-1) ⇒ a(-1)²+3(-1)-5=-15
a-3-5=-15
a-8=-15
a=-15+8
a=-7
for g(-1)=-15
then g(x)= -7x²+3x-5
It’s acute, equilateral and isosceles
