Given the following matrices are equal, what is the value of y?

Option B:

y = 6

Solution:

Given: Matrix A and Matrix B are equal.

That is elements of Matrix A and Matrix B are also equal.

To find the value of y:

In matrix A, the element in the first column second row is y + 4.

In matrix B, the element in the first column second row is 10.

Equating these two elements, we get

⇒ y + 4 = 10

Subtract 4 on both sides to equal the expression.

⇒ y = 10 – 4

⇒ y = 6

Hence the value of y is 6.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
