Evaluate 3x+4(y+3) when x is 5 less than the quotient of y and 3, and y=18.

romanna [79]

It is given that x is 5 less than the quotient of y and 3.

And given value of y is 18 .

So quotient of y and 3 is

$\frac{18}{3} = 6$

And 5 less than 6 =1

So we have y=18 and x=1

Given expression is

$3x+4(y+3)$

At x=1 and y=18, we will get

$3(1)+4(18+3) =3 + 4(21)$

$= 3+84=87$

In the rectangle below AC has a length of 28. What is the length of ED? If necessary, round your answer to two decimals places.

expeople1 [14]

<span>The diagonals of a rectangle have equal lengths. Since AC has a length of 28, and AC is a diagonal, the other diagonal BD also has a length of 28. The diagonals of a rectangle also bisect each other. So diagonal BD is bisected by the other diagonal AC at point E. And since diagonal BD has a length of 28 then BE and ED both have a length which is of 28, or 14 each.

Answer: ED has a length of 14.</span>

The average rate of change of f from 2 to 3

ella [17]

For a function of $f$ , the average rate of change can be found as follows:

$ARC=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}$

So, this problem asks for the Average Rate of Change of $f$ from $x_{1}=2$ to $x_{2}=3$ . In this way, we need to find $f(x_{1}) \ and \ f(x_{2})$ . As you can see above, we have the graph of $f(x)$ , so we can find these values. Thus, from the graph:
