You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7
solve for "k", to find k or the "constant of variation"
then plug k's value back to
now.... what is "p" when q = 5? well, just set "q" to 5 on the right-hand-side, and simplify, to see what "p" is
The correct answer is: [A]: " 2" .

5x - 4 = 3x ;
Subtract "3x" from each side of the equation;
5x - 4 - 3x = 3x - 3x ;
2x - 4 = 0 ;
Add "4" to each side of the equation;
2x - 4 + 4 = 0 + 4 ;
2x = 4 ;
Divide each side of the equation by "2" :
2x / 2 = 4 / 2 ;
x = 2 ; which is: "Answer choice: [A]: " 2" .

A polynomial is the sum of at least one term. For example, x^3+1 is a polynomial. A monomial is a polynomial with only one term, such as 2x^2.
A binomial is a polynomial with two terms, and a trinomial is one with three terms. The example you gave is a trinomial (which is also a polynomial).
Degree of a polynomial is the largest sum of variable powers in any term of the polynomial. So, for example, x^2 y has degree 3, and x^3+x^2 also has degree 3. A sixth degree polynomial would be x^6-2x+1, for example.
For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time
Substituting values we have:
y = 200 * (0.946) ^ t
Answer:
An exponential function showing the relationship between and and is:
y = 200 * (0.946) ^ t
