If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 . Which of the sets of th
pantera1 [17]

Answer:

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

c^2=a^2+b^2

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

1^2=1^2+1^2

1=2

We can see that left side is not equal to right side

so, this is FALSE

option-B

a=51

b=140

c=149

now, we can verify formula

149^2=51^2+140^2

22201=22201

We can see that left side is  equal to right side

so, this is TRUE

option-C

a=16

b=63

c=65

now, we can verify formula

65^2=16^2+63^2

4225=4225

We can see that left side is  equal to right side

so, this is TRUE

option-D:

a=6

b=8

c=11

now, we can verify formula

11^2=6^2+8^2

121=100

We can see that left side is not  equal to right side

so, this is FALSE

Which values for A and B will create infinitely many solutions for this system of equations? ax-y=8 2x+y=b
Nata [24]

Answer:

a = -2 , b = -8

Step-by-step explanation:

* Lets talk about the solution of the linear equations

- There are three types of the solutions of the system of linear equations

# If the two lines intersect each other, then there is one solution

- The equations are ax+ by = c , dx + ey = f

# If the two lines parallel to each other, then there is no solution

- The equations are ax+ by = c , ax + by = d in its simplest form ,

  where a is the coefficient of x , b is the coefficient of y and

  c , d are the numerical terms

# If the two lines coincide (over each other), then there are infinite

   solutions

- The equations are ax+ by = c , ax + by = c in its simplest form, where

  a is the coefficient of x , b is the coefficient of y and c is the

  numerical term

* Lets solve the problem

∵ The system of equation is:

   ax - y = 8 ⇒ (1)

   2x + y = b ⇒ (2)

∵ The system create infinitely many solutions

∴ The lines are coincide

- The equations must be equal, then multiply equation(1) or (2) by -1 to

  make the coefficient of y in the two equations equal

∴ -ax + y = -8

∴ 2x + y = b

∵ Their coefficients of x are equal

∵ Their coefficients of y are equal

∵ Their numerical terms are equal

∵ The coefficient of x in equation (1) is -a and in equation (2) is 2

∴ -a = 2 ⇒ multiply both sides by -1

∴ a = 2

∵ The numerical term in equation (1) is -8 and in equation (2) is b

∴ b = -8

* The values for a and b will create infinitely many solutions are -2 , -8
