Answer:

Step-by-step explanation:

if the triangles are similar then EG/BC = FG/BD

51/(x+4) = 57/(2x-7) cross multiply expressions

102x - 357 = 57x + 228

102x - 57x = 228 + 357

45x = 585 divide both sides by 45

x = 13

BD = 2x -7 and 13×2 - 7 = 19

Answer: negative.

Step-by-step explanation:

We know that the slope of the line $\frac{\text{change in y}}{\text{change in x}}$

Therefore, the slope for the given data $=\frac{y_2-y_1}{x_2-x_1}$

$\Rightarrow\ Slope=\frac{795-875}{20-10}\\=\frac{-80}{10}\\=-8...,\text{which is negative.}$

Hence, the word which describes the slope of the line representing the data in the table = negative.
