Write in function form 5x + 4y = 20.

Mathematics
1 answer:
xenn [34]3 years ago
6 0

Answer:

Step-by-step explanation:

5x + 4y = 20

You need to express y in terms of x.

isolate the y term

4y = -5x + 20

divide both sides by the coefficient of y

y = (-5/4)x + 5

f(x) = (-5/4)x + 5

How to find a local minimum of a function?
ser-zykov [4K]

Answer:

  Find the places where the derivative is zero and the second derivative is positive.

Step-by-step explanation:

By definition, a function has a minimum where the first derivative is zero and the second derivative is positive.

That will be a "local" minimum if there are other points on the function graph that have values less than that. It will be a "global" minimum if there are no other function values less than that. A global minimum is also a local minimum.

__

On a graph, a local minimum is the bottom of the "U" where the graph changes from negative slope to positive slope.

What is the point-slope form of the equation for the line with a slope of 6/19 that passes through the point (−1,75)?
Umnica [9.8K]

Answer:

The answer is

<h2>y =  \frac{6}{19} x +  \frac{1431}{19}</h2>

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (−1,75) and slope 6/19 is

y - 75 =  \frac{6}{19} (x + 1) \\ y - 75 =  \frac{6}{19} x +  \frac{6}{19}  \\ y =  \frac{6}{19} x +  \frac{6}{19}  + 75

We have the final answer as

y =  \frac{6}{19} x +  \frac{1431}{19}

Hope this helps you

This is kinda hard to explain but i'll try.
First off, don't do online school.
Second, don't look up answers.

The gcf of the first two terms is 3g^2 and the gcf of the second two terms is 5
3g^2(g + 2) + 5(g + 2)
