14) The answer is a) y = 2x. 2 is the slope and the line does not cross over the Y axis in this picture so there is not a Y-intercept you can see.
15) You pretty much just estimate. On the graph when you find 50 minutes and go up its around 140. 50 x 2 is 100 minutes. so just multiply 140 by 2 and its 280 so just round to the closest one.
Supplementary Angles:
Arithmetically speaking, the closest 2 supplementary angles can get (in 3 and 2 digits respectively) is the upwritten.
Complementary Angles:
Simply, in this case, for angles to be numerically as close as possible - make both the angles 45°.
Answer:
20x + 22
Step-by-step explanation:
34- 4x + 12x -12 +12x
step 1: 34 - 12 = 22
now you have left: -4x + 12x +12x
step 2: 12x +12x = 24x
step 3: 24x - 4x = 20x
Now you will combine the two answers you got: 20x +22
Hope this helps :)
