<em>Answer:</em>

<em><u>X = 80</u></em>

<em>Step-by-step explanation:</em>

<em>Subtract </em><em>"5"</em><em> from both sides,</em>

<em>3x + 5 - 5 = 245 - 5</em>

<em><u>Simplify,</u></em>

<em>3x = 240</em>

<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>

<em>3x/3 = 240/3</em>

<em>X = </em><em>80</em>


<u><em>Hope this helps :-)</em></u>

3x + 5 = 245
Subtract 5 from both sides to get x alone on one side
3x = 246
Now divide by 3 on both sides
x = 82

Consider the function f ( x ) = 1 − 4 x 2 on the interval [ − 1 , 3 ] . Find the average or mean slope of the function on this i
Blababa [14]

Answer:

The average slope is 8.

Step-by-step explanation:

Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient

                                       average slope = \frac{f(b)-f(a)}{b-a}

To find the average slope of the function f(x)=1-4x^2 on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.

So,

f(-1)=1-4(-1)^2=-3\\\\f(3)=1-4(3)^2=-35

The average slope is  \frac{f(3)-f(-1)}{3+1}= \frac{-3+35}{3+1}=\frac{32}{4}=8
