[Answered] Consider the data points (–4, –14), (–2, –7), (0, –3), (2, –2), and (6, –6). Which type of function would best model the data set? A. exponential B. linear C. quadratic

[Answered] How can caregivers best recognize subtle changes in health or behavior?

[Answered] Serina wants to solve the following system of equations in the most efficient way. [tex]$\begin{array}{r} 2 x+3 y=18 \ x+7 y=31 \end{array}$[/tex] She plans to solve for [tex]$x$[/tex] in the first equation as her first step since both 2 and 3 can be divided into 18. Why is Serina mistaken? A. Serina should have solved for [tex]$x$[/tex] in the second equation because it has a coefficient of 1. B. Serina should have solved for [tex]$y$[/tex] in the first equation because dividing by 3 instead of by 2 would give a smaller number in the solution. C. Serina should have solved for [tex]$y$[/tex] in the second equation because it has the largest coefficient. D. Serina should have solved for [tex]$y$[/tex] in the first equation because the division step will be easier since 18 is divisible by 3.

[Answered] x^2 + b^2 + a^2 + b^2 + c^2 + CD^2

[Answered] Which equation is related to $\sqrt{x+10}-1=x$? A. $x+10=x^2+x+1$ B. $x+10=x^2+2 x+1$ C. $x+10=x^2+1$ D. $x+10=x^2-1$

[Answered] Which expression is equivalent to $\sqrt[4]{\frac{24 x^6 y}{128 x^4 y^5}}$ ? Assume $x \neq 0$ and $y>0$. A. $\frac{\sqrt[4]{3}}{2 x^2 y}$ B. $\frac{x(\sqrt[4]{3})}{4 y^2}$ C. $\frac{\sqrt[4]{3}}{4 x y^2}$

[Answered] For [tex]f(x)=4 x+1[/tex] and [tex]g(x)=x^2-5[/tex], find [tex](f+g)(x)[/tex]. A. [tex]x^2+4 x-4[/tex] B. [tex]x^2+4 x+6[/tex] C. [tex]4 x^3-4[/tex] D. [tex]4 x^2-19[/tex]

[Answered] Which sentence contains a noun clause? a. The boy who won is my friend. b. He ran because he was scared. c. She asked why he was late d. If you study hard, you will succeed.
