Arithmetic sequence decreases by adding or subtraction a number exg 2,4,6,8
geometric sequence is mu;ltipliying or dividing by a number exg
2,4,8,16,32 etc
so it from 64 to 4 then to 1/4
64/16=4
4/16=1/4
it decreases by a factor of 1/16
it is geometric
th enaswer is B
Answer:
Step-by-step explanation:
∠ADC = 90°
∠ADB + ∠BDC = 90
20 + ∠BDC = 90
∠BDC = 90 - 20 = 70
∠BDC = 70°
16) ∠PSR = ∠PSQ +∠QSR
= 60 + 10
= 70
18) ∠PSR = 130
∠PSQ + ∠QSR = 130
90+ ∠QSR = 130
∠QSR = 130 - 90
∠QSR = 40
19)∠ADC = ∠ADB + ∠BDC
= 120 +20
= 140
20) ∠PSR = 125
Answer:
1. Lets say that you get the coords. (1,2). X would be the first one (1), and Y would be the second number (2). if you got 2/1, then, because of rise/run, that 2 would be Y and 1 would be X
2. ?
3. Slope is rise/run (Y/X), and the Y intercept is where the line intercepts the Y axis.
I literally have no idea how to answer 2, but I hope that I helped a bit :)
