We can use special triangles to solve for x in triangle A<br>true or false

KIM [24]

I believe the answer is false.

explanation: a special triangle has side lengths of 3-4-5 or 6-8-10. In this case since you have 10 one of the other sides would have to be 6 or 8. You can use pythagorean theorem.

Use the linear combination method to solve.<br><br> {x+2y=1 x−2y=5

k0ka [10]

Answer:

Step-by-step explanation:

1) x+27=1

-27 -27

x = -26

2) x-2y=5 (solving for x)

+2y +2y

x = 5 + 2y

2) x-2y=5 (solving for y)

-x -x

2y = 5 -x

2y/2 5/2 -x/2

y = 5 - x

4. If u = {1,2,3,....10) A = { odd numbers up to 9} B = {numbers less than 7). Write out the members of the following sets: (i)

icang [17]

Answer:

i. {1,2,3,4,5,6,7,9}

ii. {1,3,5}

iii. {1,2,3,4,5,6,8,10}

Step-by-step explanation:

U= {1,2,3,4,5,6,7,8,9,10}

A= {1,3,5,7,9}

B= {1,2,3,4,5,6}

A U B = {1,2,3,4,5,6,7,9}

A n B = { 1,3,5}

A (prime) U B =

A(prime)= {2,4,6,8,10}

Therefore A(prime)= {1,2,3,4,5,6,8,10}
