Find the value of y when x=0 using the equation y=-2/3x +4. Explain
1 answer:
<u>Given </u><u>:</u><u>-</u>
- y = 2/3x + 4 .
<u>To </u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The value of y when x = 0 .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given equation to us is ,
y = -2/3x + 4
So when we substitute x = 0 , we have ,
y = -2/3 *0 +4
y = 0 + 4
y = 4
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is</u><u> </u><u>4</u><u>.</u>

Answer:
Domain of the function is { x : x∈R, x>0 } or (0,∞).
Step-by-step explanation:
It is given that the dimensions of a rectangular piece of cardboard are
Length = 14 inch
Width = 10 inch
The box will be constructed by cutting out equal squares of side x at each corner and then folding up the sides. So the dimensions of the box are
Length = 14-2x inch
Breadth = 10- 2x inch
Height = x inch
The volume of cuboid box is
The volume function of the box is
The volume function is V=(14-2x)(10-2x)x.
It is a polynomial function and domain of a polynomial function is all real numbers.
Here, x represents the height of the box. So, value of x must be a positive real number.
Domain of the function is
Domain = { x : x∈R, x>0 }
It can be written as (0,∞).
Therefore, domain of the function is { x : x∈R, x>0 } or (0,∞).
