4x+c=w make x a subject
plz help me
answer me fast
and i want answer kn step by step

x= (w-c)/4

Step-by-step explanation:

Making a variable a subject is basically isolating it on one side. So in this case to make "x" a subject, we are just trying to get it alone on one side. You are solving for x.

1. Write the problem> 4x+c=w

2. Subtract "c" from both sides > 4x=w-c

3. Divide by 4 on both sides. You would need to divide (w-c) by 4 because the 4 has to apply to both variables!> x=(w-c)/4

x =w-c/4

Step-by-step explanation:

solution

here,

4x+c=w

or, 4x=w-c

:.x=w- c/x

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
