Answer: The non-permissible replacement for this expression is y = 0.

In math, we cannot divide by 0. It is not allowed. Therefore, in this problem, we cannot divide be 0. 

In other words, the denominator can't be 0.

So we can write and solve the following equation to determine what would make the denominator 0.

-5y = 0   Divide by -5
y = 0

Y cannot be 0 in this expression.

We have that
<span>(3/-5y)

we know that
</span><span>zero in the denominator is NOT allowed
</span><span>y = 0 is the non permissible replacement for y in this expression </span>
the domain of this <span>expression is all y value real numbers except the value of y=0

domain is (-</span>∞,0) ∩ (0,∞)

the answer is 
y=0

-The length is x feet.

- The width is y feet.

- The height is z feet.

2. The box has one base. The cost of the base is:

c1=4.20xy

3. It has four sides. The cost of the sides are:

c2=2(0.75yz)+2(0.75xy)\\ c2=1.5yz+1.5xy

1. Find the value of x.<br> 55°<br> (4x - 5)°<br> O<br> 26<br> O
Paha777 [63]

Answer:

26

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees, use this and set up an equation;

x + ( 4x -5 ) + 55 = 180

Simplify

x + ( 4x - 5 ) + 55 = 180

5x + 50 = 180

Inverse operations;

5x + 50 = 180

    -50     - 50

5x = 130

/5    /5

x = 26
