Answer:

Table A represents a function, but Table B does not represent a function.

Step-by-step explanation:

We have to select the correct option among the given 4 options after judging the given two tables attached to this question.

The first table shows that for each x values there is only one y value. Therefore, this is a function.

But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.

Hence, table B is not a function. it is just a relation. (Answer)

What is the fully factored form of the expression 16x^2 - 49y^2

podryga [215]

Answer:

(4x + 7y)(4x - 7y)

Step-by-step explanation:

Rewrite 16 as 4^2

= 4^2x^2 - 49y^2

Rewrite 49 as 7^2

= 4^2x^2 - 7^2y^2

Apply the Exponent Rule Pt 1 ((a^m*b^m =(ab)^m))

= (4x)^2 - 7^2y^2

Apply the Exponent Rule Pt 2

= (4x)^2 - (7y)^2

Apply Difference of Squares Formula (( x^2-y^2 = (x + y)(x - y)

= (4x + 7y) (4x - 7y)

What is the domain of the function y = -4x+1 if the range is -11

a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

$y=-4x+1$

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

$x=-\frac{1}{4}(y-1)$

If the range of the original function is the set given by the number {

What is the square root of 500

noname [10]

500 is not a perfect square number. Therefore, find the factors of 500 with the largest perfect square. In this case, 100 is the largest perfect square number in 500.
$500= \sqrt{500} ^2$

$\sqrt{500}=\sqrt{100*5}$

$\sqrt{500}=\sqrt{100}\sqrt{5}$

$\sqrt{500}=10\sqrt{5}$

If you are simply looking for the calculator result, you will get $22.36$
