Answer: i gave you another example i just had to help you

Step-by-step explanation:

A)  8²+ 10²=x²

 

B) x + 8 = 10

 

C)  x²+8²=10

 

D)  x²+ 10²=8²

 

EXPLANATION:

A)  

Incorrect. In this triangle, you know the hypotenuse (the side opposite the right angle) has a length of 10. The lengths of the legs are 8 and x. The correct answer is .

 

B) x + 8 = 10

Incorrect. The Pythagorean Theorem is a relationship between the lengths of the sides squared. The correct answer is .

 

C)  

Correct. In this triangle, the hypotenuse has length 10, and the legs have length 8 and x. Substituting into the Pythagorean Theorem you have: ; this equation is the same as , or . What number, times itself, equals 36? That would make x = 6.

 

D)  

Incorrect. In this triangle, the hypotenuse has length 10 (always the longest side of the triangle and the side opposite the right angle) not 8. The correct answer is

Write a system of linear equations that has the ordered pair (1,4) as it's solition
Lemur [1.5K]

The required system of equations is x+y=5\\x-y=-3

Step-by-step explanation:

We need to write a system of linear equations that has the ordered pair (1,4) as it's solution.

It means we need to find  system of linear equations, which after being solved gives x=1 and y=4

Let the system of equations be:

x+y=5\\x-y=-3

I have made equations such that adding x+y gives 5 i,e (1+4=5) and subtracting x-y gives -3 (1-4=-3)

Now solving this system of equations to find value of x:

x+y=5\,\,eq(1)\\x-y=-3\,\,eq(2)

Adding eq(1) and eq(2)

x+y=5\\x-y=-3\\-----\\2x=2\\x=1

Putting value of x=1 into eq(1) to find value of y

x+y=5\\1+y=5\\y=5-1\\y=4

The solution set after solving system of equations is (1,4).

The required system of equations is x+y=5\\x-y=-3
