Triangle ABC has vertices at A(-3, 5), B(0, 0), and C(6, 5). It is transformed so that Triangle A'B'C' has coordinates A'(1, 11)

Alisiya [41]

Jacob is incorrect. The transformation was no a reflection, but a translation. The transation was (x+11,y+6)(11 units rigth and 6 units up). (Explain what the points would have been if it was a reflection across the x-axis)

sladkih [1.3K]

Answer:

Step-by-step explanation:

Substitute the value of the variable and simplify.

$(-(2))^{(2+2)} +2^{(2-2)}$

$-2x^{2+2} =2^{4} = 16$

$2^{2-2} =2^{0}$

Anything raised to the power of 0 is one.

16 + 1 = 17

U=(1,2,3,4,5,6,7,8),a=(1,3,5,7), b=(4,5,6) is it true statement

kvv77 [185]

<u>Answer:</u>

U=(1,2,3,4,5,6,7,8), a=(1,3,5,7), b=(4,5,6) is false statement

<u>Solution:</u>

Given, two sets are a = (1, 3, 5, 7) and b = (4, 5, 6).

And their union set is U = (1, 2, 3, 4, 5, 6, 7, 8)

We have to find that whether above sets are true or not.

We know that, union of two sets will have the all elements in the two sets except the repeated elements.

Now, according to our knowledge.

Union of a and b = (1, 3, 5, 7, 4, 6)

Now compare the given union set with our set.

After comparison we can say that, both are not equal which means that given union set is false set.

Hence, given statement is false.
