Step-by-step explanation:

formally, there is only one alternative : if not negative, it would be a positive number.

and that would mean

2× -4/5 = x (= a positive number)

2× -4 = 5x (= still a positive number)

-4 = 5x/2 (= still a positive number)

and -4 is definitely not a positive number.

so, it is proven, 2× -4/5 cannot be a positive number, and therefore has to be a negative number.

Step-by-step explanation:

please find the correct question:

In choice a:

The smallest square line would be from the production.

$Sales = -7.567857143 + 0.917857143 \times Makeup\ Videos.$

Purchases of Cosmetics & Makeup Demo Clips are the factors used in the calculation.

In choice b:

The proportions of its variance of maquillage sales reveal by it's a linear relation to maquillage video tutorials is $99.53 \ \%$ .

In choice c:

Because the vector Cosmetics Demonstration videos are critical with 5.11E-07 p-value, which is less than 0.05 and $R^2 = 99.53$ . It may assume that increasing making-up purchases is attributed to tutorials for online makeup.

Answer:

yes, triangle DEF is similar to triangle DBC, BC corresponds to EF, and angle DCB corresponds to angle F.

Step-by-step explanation:

Part A: Angle D is congruent to angle D by the reflexive property. Since line BC is parallel to line EF then angle DCB = angle DFE by corresponding angles. Hence triangle DEF is similar to triangle DBS by the AA Similarity Postulate.

Part B: BC corresponds to EF because they are in the same order and the triangles listed DEF and DBC

Part C: Angle DCB corresponds to angle F since they are corresponding angles with the two given parallel lines BC and EF.
