Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

To find the slope, we need any two points on the line --> (0,4) and (3,0)

$Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}$

2. Set up, with any one point on the line and the slope, in point-slope form

$(y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4$

<u>Answer</u>: $\frac{4}{3}x+y = 4$

Hope that helps!

F(x)=x^2+3x-5. find and simplify f(x+h)-f(x)

jarptica [38.1K]

Answer:

$f(x + h) - f(x) = h^2 + 3h - 5$

Step-by-step explanation:

Given

$f(x) = x^2 + 3x - 5$

Required

Find f(x + h) - f(x)

In functions:

$f(x + h) = f(x) + f(h)$

So:

$f(x + h) - f(x) = f(x) + f(h) - f(x)$

Collect Like Terms

$f(x + h) - f(x) = f(x) - f(x)+ f(h)$

$f(x + h) - f(x) = f(h)$

Solving for f(h)

$f(h) = h^2 + 3h - 5$

So:

$f(x + h) - f(x) = h^2 + 3h - 5$
