Answer:

Number 1 can form a right triangle. Numbers 2 & 3 cannot.

Step-by-step explanation:

To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.

5² + 12² = 13²

25 + 144 = 169

169 = 169

<u><em>They are equal therefore Number 1 can form a right triangle.</em></u>

5² + 7² = 9²

25 + 49 = 81

74 = 81

<em>They are not equal, therefore Number 2 can't form a right triangle.</em>

<em />

10² + 12² = 30²

100 + 144 = 900

244 = 900

<em>They are not equal, therefore Number 3 can't form a right triangle.</em>

Is (–5, 0.5) a solution of this system? x – 4y = –7, 0.2x + 2y = 0 Substitute (–5, 0.5) into x – 4y = –7 to get . Substitute (–5
kaheart [24]

<u>ANSWER: </u>

(-5, 0.5) is the solution of given equation x – 4y = –7, 0.2x + 2y = 0.

<u>SOLUTION: </u>

Given, two equations are x – 4y = -7 → (1)

And 0.2x + 2y = 0 → (2)

We have to find whether (-5, 0.5) is a solution of given system or not.

For that, we have to solve the given two equations.  

Before solving let us multiply equation (2) with 2 in order to get y terms cancelled. Such that, our  process becomes easy.  

Now equation (2) becomes

0.4x + 4y = 0 → ( 3 )

Now, add equation (1) and equation (3), we get

1.4x + 0 = -7

x=\frac{-7}{1.4}=-5

Now, substitute x value in (2)

0.2(-5) + 2y = 0

-1 + 2y = 0

2y = 1

y = 0.5

So, the solution for given equations is (-5, 0.5).

Hence (-5, 0.5) is the solution of given equations.
