Write the equation in function form:
8x + 4y = 20

Answers

Answer 1
Write 8x+4y=20 in function form


Writing a an equation in function form is simply expressing y values in terms of x. In other words when you substitute a particular value for x, you get a particular value for y.

so

8x + 4y = 20

4y = 20 - 8x

y = (20-8x)/4 or y = (20-8x)/4 or y = f(x) = 2(10-4x)/4 = (10-4x)/2 = 5 - 2x = -2x+5

check your answer with a sample values say with a point that solves the equation or a point on the line.....see below....

(2,1)

8(2) + 4(1) = 20......16 + 4 = 20...check.......y=-2(2) + 5 = -4 +5 =1....x=2, y=1...checks....so f(x)=-2x+5

another quick check are the intercepts.....y (x=0)....or x (y=0)

8 (0) + 4 (5) = 20.....(0,5).......y=f(x) = -2 (0) + 5...x = 0..y=5 so again the function checks so

8x + 4y = 20.....is also written as the function y= f(x)= -2x + 5

What is the first step when solving the equation 3 (3x - 5x) + 2 = -8?

Answers

Answer:

Distribute

Step-by-step explanation:

You will want to distribute 3 by 3x and -5x, Which will then make your equation

9x-15x+2=-8

You are using pemdas in this equation so there for you distribute first .
Example : 3(3x-5x)+2=-8
You will multiply
3 (3x-5x)
9x -15 x +2=-8
Then add and subtract with same variables
-6x = -6
Then you divide by -6
X=1

Step-by-step explanation:

First, you need to get the variable by itself. To do that you do the opposite of multiplication, which is division. 9.20p divided by 9.20 is just p.

Second, whatever you do to one side you have to do to the other, so you divide 299 by 9.20 to get 32.5.

Bonding is related to the electrons in an atom, and there are different kinds of bonds. As a result, some substances can have the same atoms but different bonds.
