19+x/2=4
multiply 2 on both sides
19+x=4 times 2
19+x=8
subtract 19 on each side
x=8-19
subtract
x=-11
What do you mean? I don't think it's enough information
Answer:
yes all are right
Step-by-step explanation:
The given expression written in the simplest rational exponent form is 
<h3>Writing an Expression in Exponent form</h3>
From the question, we are to write the given expression in exponent form
The given expression is
![\sqrt{x} \times \sqrt[4]{x}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%20%5Ctimes%20%5Csqrt%5B4%5D%7Bx%7D)
In exponent form,

and
![\sqrt[4]{x} = x^{\frac{1}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%7D%20%3D%20x%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D)
Thus,
becomes

Applying the multiplication law of indices, we get

= 
Hence, the given expression written in the simplest rational exponent form is

The polynomial that passes through the point (5,100) has the leading coefficient or c equal to 1.38.
<h3>What do a polynomial's leading term and leading coefficient mean?</h3>
- The term with the highest power of x is the leading term in a polynomial.
- As an illustration, the leading term in 7+x3x2 is 3x2. A polynomial's leading coefficient is the coefficient of the leading term. The leading coefficient in the aforementioned illustration is 3.
We need to determine the leading coefficient c of the polynomial which passes through the point (5,100).
Given polynomial: f(x) = c(x - 1)(x + 1)(x-2)
Substituting f(x) = 100 and x = 5,
100 = c(4)(6)(3)
100 = c72
c= 1.38
Therefore, the leading coefficient c of the polynomial given that the graph goes through the point (5,100) is 1.38.
