Answer:
(x,y)=(0,-1)
Step-by-step explanation:
Observe that the equation
can be transformed in the equation of a line

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that
.
Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.
Answer:
20in²
Step-by-step explanation:
The area of a triangle is calculated using the formula A = bh/2
"A" means area.
"b" is for the base.
"h" is for the height.
It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.
5in can be the height.
8in can be the base.
Put the base and height measurements into the formula.
A = bh/2
A = (8in)(5in)/2 Multiply the measurements and the units.
A = (40in²)/2 Divide by 2
A = 20in² Area of the triangle
When you multiply units, in X in becomes in².
"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.
in¹ X in¹ = in¹⁺¹ = in²
