Answer:
y = 2x
linear equations are just finding the right ratio and putting it in y = mx+b format
this graph is saying that two dollars are earned for every ticket sold, a 2:1 ratio.
so the equation would be y = 2x, two being the amount of money collected for one ticket, and x being the number of tickets sold.
<span>Slope is calculate by dividing the change in y-values by the change in x-values between a pair of points.
For 7: (7-1)/(1-10) = 6/-9 = -2/3
For 8: (6.1-3.1)/(-5.5 - -2.5) = 3/-3 = -1
For 9: (5/2 - -3) / (-5 - -7/3) = 11/2 / -8/3 = -33/16. This is not an answer option, so double check the problem.</span>
Answer:
1 11/20
Step-by-step explanation:
3 3/4 - 2 1/5 = 3 15/20 - 2 4/20 = 1 11/20
Answer: D) 10
Step-by-step explanation:
<u>All angles in a triangle adds up to 180°</u>
60° + 50° + 7x = 180°
7x = 180° - 60° - 50° = 180°- 110° = 70°
x = (70 ÷ 7)° = 10°
