Hello there, this is how we will solve your problem.\

here is the equation you gave us.

{\huge{\boxed{\mathbb{EQUATION}}}

\begin{bmatrix}-5x+y=-3\\ 3x-8y=24\end{bmatrix}

we can isolate x and say x=\frac{-3-y}{5}

Now here is our equation, \begin{bmatrix}3\left(-\frac{-3-y}{5}\right)-8y=24\end{bmatrix} After we simplify it we get \begin{bmatrix}\frac{9-37y}{5}=24\end{bmatrix}, solve this and we get that y=-3, Before we said x equals -\frac{-3-y}{5}, So now we can plug in our value that y equaled, and now we have \frac{-3-(-3)}{5}. Two negatives equal a positive and we get that x=0.

Is AFGH ~ AJKL? If so, identify the similarity postulate or theorem that
ad-work [718]

Answer: B. Cannot be determined

Explanation:

We can't use SAS since we don't have two pairs of proportional sides. We only know one pair of sides. This also rules out SSS as well since we'd need 3 pairs of proportional sides.

We can't use AA because we don't have two pairs of congruent angles.

Currently, we simply don't have enough information to determine if the triangles are similar or not.

Part 1: The zeroes are -5 with a multiplicity of 2, -1 with a multiplicity of 1, 4 with a multiplicity of 3, 7 with a multiplicity of 1.

Part 2: The possible factored form of the function is (x + 8)^2(x + 1)(x - 4)^3(x - 7)
