Answer:
it means y intercept
Step-by-step explanation:
Answer:
7 feet and 24 feet
Step-by-step explanation:
In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.
Let x feet and y feet be the lengths of triangle's legs.
By the Pythagorean theorem,

The area of the right triangle is half the product of its legs, thus

Solve the system of two equations:

From the second equation:

Substitute it into the first equation:

The length of the leg cannot be negative, so

Answer:
<h2>h = 15</h2>
Step-by-step explanation:
The formula of an area of a parallelogram:

b - side
h - height
We have b₁ = 18 and h₁ 10 and b₂ = 12.

Substitute:

<em>divide both sides by 12</em>

Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.
