13. Written as an equation: Y = P% * X.

The 'what' is Y that we want to solve for.

Remember to first convert percentage to decimal, dividing by 100.

Solution: Solve for Y using the percentage formula. Y = P% * X.

Step-by-step explanation: just switch up a few words here and there on 13 and you should be good to go!

If trinalge abc= def by side-side-side triangle congruence theorem, then b=e by

Anna007 [38]

Answer: D: Corresponding parts of congruent triangles are congruent

Step-by-step explanation:

If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.

The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.

Here if triangle abc= def by side-side-side triangle congruence theorem,

then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.

between 1995 and 2006, the population of samburg, usa(in thousands) can be modeled by f(x) = 0.35x(squared) - 2.1x+15.8 where x=

Juli2301 [7.4K]

$\bf f(x)=0.35x^2-2.1x+15.8\qquad 
\begin{cases}
x=\textit{year since 1995}\\
f(x)=\textit{population amount}
\end{cases}$

the equation is a quadratic one, and it has a positive coefficient on the leading term, meaning, is opening upwards, so it has a "burrow" for the vertex.

the minimum or lowest point for a quadratic opening upwards is, well, the vertex point :), the "x" value is the year, the "y" or f(x) value is the population, we're asked for the year, or the x-coordinate of the vertex

well $\bf \begin{array}{llll}
f(x)=&0.35x^2&-2.1x&+15.8\\
&\quad \uparrow &\quad \uparrow&\uparrow \\
&\quad a&\quad b &c
\end{array}
\\\\
