The equation you would use to find her earning for the week would be:

y=0.03(x-1000)+150

Create a 5th degree trinomial that has a constant term of 3.

erastovalidia [21]

Answer:

$4x^5\:+\:9x^2\:+\:3$ is a trinomial having three terms, with degree 5 and the constant term '3'.

Step-by-step explanation:

Considering the trinomial

$4x^5\:+\:9x^2\:+\:3$

As the polynomial contains 3 terms, so it is a trinomial.

As the highest power of the variable 'x' is 5, so the degree of this polynomial is 5.

Any term with no variable is called a constant term. so, 3 is a term with no variable. Therefore, the constant term is 3.

Therefore, $4x^5\:+\:9x^2\:+\:3$ is a trinomial having three terms, with degree 5 and the constant term '3'.

Answer:

B. 18

Step-by-step explanation:

$x^{2} + 36x + 324 = (x + m)^{2}$

$(x+18)^{2}= (x + m)^{2}$

$\cancel x+18= \cancel x + m$

$18= m$
