Question

Which conditional and its converse are both true?

If x = 3, then x2 = 6.
If x = 2, then x2 = 4.
If x2 = 4, then x = 2.
If x = 1, then 2x = 2.
- i think its C but i dont know

Answer 1

B and D are both correct...
in case of C If x2 = 4, then x = +2,-2 which is not an option

Answer 2

im confused

Answer 3

Let's look at each one.
A. If x = 3, then x2 = 6.
Is this true?

Answer 4

you;re confused about C or B and D?

Answer 5

What is \(3^2 =\)

Answer 6

c

Answer 7

im confuced a bout c

Answer 8

C. If \(x^2 = 4\), what can x =?
What numbers squared = 4?

Answer 9

C says If x2 = 4, then x = 2.
which is incorrect
\[x=\sqrt{4}=+2 , -2\]

Answer 10

\[(-2)^{2}=2^{2}=4\] remember?

Answer 11

ok well idk if my are just tried but it look to me that a is correct

Answer 12

A can't be right...
see If x = 3, then x^2=3^2=9
while A says If x = 3, then x^2 = 6.

Answer 13

then which one is correct

Answer 14

nm b is correct

Answer 15

thank you guys

Answer 16

You're not done.

Answer 17

For each conditional, you need to see if both the conditional and its converse are true.

Let's start with A.:
If x = 3, x^2 = 6.
This is false since 3^2 = 9, so
if x = 3, x^2 = 9 not 6.
Here the conditinal is false, so there is no need to check the converse.

Answer 18

B. If x = 2, then x2 = 4.
This conditional is true. If x = 2, 2^2 = 4.
Now we need to check the converse.
If x^2 = 4, then x = 2.
This converse is false. If x^2 = 4, then x = -2 or +2.
For B. the conditional was true but the converse was false. So B. is not the answer.

Answer 19

C. If x2 = 4, then x = 2.
If x^2 = 4, then x = -2 or +2.
This conditional is false, so there is no need to check its converse.

Answer 20

D. If x = 1, then 2x = 2.
This conditional is true. If x = 1, then 2x = 2(1) = 2,
or you can multiply both sides by2 to get 2x = 2.
Now let's check the converse:
If 2x = 2, then x = 1.
We divide both sides by 2, to get:
x = 1.
The converse is also true.
The answer is D. because that is the only conditional that is true , and its converse is also true.

ok i get it thank you for explaining
