Answer:

y(x) = x + 4

Step-by-step explanation:

A function rule is nothing more than a process that correlates changes in input to changes in output. If y is the output and x is the input, the function must be of the form y(x). Since "The output is four more than the input", the value of y is always 4 units greater than the value of x. The function rule is:

$y(x) = x + 4$

Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

$( \frac{2}{3} - \frac{1}{4} ) + ( \frac{1}{2} \times \frac{1}{3} )$

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

$\frac{2}{3} - \frac{1}{4} = \frac{8 - 3}{12} = \frac{5}{12}$

Next multiply the other terms in the other bracket

That's

$\frac{1}{2} \times \frac{1}{3} = \frac{1}{6}$

Add both results

That's

$\frac{5}{12} + \frac{1}{6}$

Find the LCM

The LCM is 12

We get the final answer as

$\frac{5}{12} + \frac{1}{6} = \frac{5 + 2}{12} = \frac{7}{12}$

Hope this helps you

Can you chose which option it is

ohaa [14]

Answer:

Step-by-step explanation:

8x + 2 + 70 + 60 = 180 ( sum of all angles of a triangle = 180 degree )

8x + 132 = 180

8x = 180 - 132

8x = 48

x = 48 / 8

x = 6

Therefore 3 rd option is correct.

Hope this helps

Which of the expressions below can be factored using the difference of squares method? A. 25x2 - 64y2 B. 17x2 + 23y2 C. 17x2 - 2

denis-greek [22]

<span>Difference of squares method is a method that is used to evaluate the difference between two perfect squares.

For example, given an algebraic expression in the form:
$x^2-y^2$
can be factored as follows:
$(x-y)(x+y)$

From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e. $25x^2-64y^2$
which can be factored as follows:
$(5x-8y)(5x+8y)$ .</span>
