For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...
5-2
——. = 3/4
11 - 7
For question 5: input the values of x,y and the gradient into the equation of a line.....
y = mx+ c
-8 = 3(-2) + c
-8 = -6 + c
-2 = c
therefore:
y = 3x - 2
Hope this helps! Any questions let me know :)
Answer:
Common communication channels in mass communication include television, radio, social media, and print media. Examples of mass communication include commercial advertising, public relations, journalism, and political campaigning.
Step-by-step explanation:
Answer: x= 83
Why? It’s on a straight line which is 180 degrees so take 97 and subtract it from 180
180-97=x
X= 83
Hope this helps
Answer:
A. Translate triangle ADE so that point D lies on point B to confirm angle D is congruent to angle B.
Step-by-step explanation:
Two triangles are said to be similar if the ratio of their corresponding sides are equal.
The AA Similarity Postulate states that If two angles of one triangle is congruent to two angles of another triangle, then the two triangles are similar.
Translation is the movement of a point up, down, left or right.
Since ∠A = ∠A (reflexive property of congruence)
We have to prove that ∠D = ∠B, by Translating triangle ADE so that point D lies on point B
