If f(x) = startfraction 7 over x endfraction, then what is the slope of f(x) at x = 5? round your answer to 3 decimal places.
Flura [38]

The slope of the function to 3 dp is 0.280

<h3>Slope of a function</h3>

Slope is also known as the gradient of a function

Given the function f(x) =\frac{7}{x}

Taking the derivative of the function will give:

f'(x)=-\frac{7}{x^2}

Substitute x = 5 into the equation to have:

f'(x)=-\frac{7}{5^2}

f'(x) = -\frac{7}{25}

Hence the slope of the function to 3 dp is 0.280

Veronika [31]

Answer: 9x+y=-6

Step-by-step explanation:

Standard: Ax+By=C

y=-9x-6

We need -9x on the left side, to move it, we must add 9x on both sides.

9x+y=-9x-6+9x\\9x+y=-6

Done. We have Ax = 9x, By = 1y and C after the equal sign = -6
