When the line segement is dilated , the resulting line is parallel to the original line. Know that the the slopes of parallel lines are equal. Therefore, the slope of the line passing through (-2,10) and (7,4) is equal to the slope of the new line .

Basically, we will just have to compute for the slope using the points (-2,10) and (7,4).

\begin{gathered} \text{slope, m = }\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{4-10}{7-(-2)}=\frac{-6}{9}=-\frac{2}{3} \end{gathered}

(x+3)(x-5)-(4x+1)(1-4x)=17x^
Greeley [361]

Answer: \boxed{Sol=\{\dfrac{7}{4} \}}\\

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

(x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\

Is the sequence 2, 1, 1/2, 1/4,.. A)arithmetic B) geometric C) both D)neither
Sonbull [250]
The given sequence is a geometric sequence. The property of geometric sequence is that each term is multiplied by a specific number known as "common ratio" to get the next term. In this case the common ratio is 1/2.
2 x 1/2 = 1
1 x 1/2 = 1/2
1/2 x 1/2 = 1/4 
and so on..
