C is the answer i believe
<u><em>Answer: </em></u>
#9: 5
#10: -2
#11: -1.5
<em><u>Step-by-step explanation:</u></em>
<em><u>#9:</u></em> 3,8,13,18,23,(28),(33),(38),.. <em>Go up by 5 each time, so the common difference is </em><u><em>5</em></u><em>.</em>
<u><em>#10:</em></u> 11,9,7,5,3,(1),(-1),(-3),... <em>Go down </em><em>(-)</em><em> by 2 each time, so the common difference is </em><u><em>-2</em></u><em>.</em>
<u><em>#11:</em></u> 3, 1.5, 0, -1.5, -3, (-4.5), (-6), (-7.5),... <em>Go down </em><em>(-) </em><em>by 1.5 each time, so the common difference is </em><u><em>-1.5</em></u><em>.</em>
Answer:
y = -1/3x + 1
Step-by-step explanation:
substitute the given values in y = mx + b where m is the slope and b is the y-intercept
y = -1/3x + b
at point (0, 1)
1 = -1/3 × 0 + b
1 = 0 + b
b = 1
y = -1/3 + 1
Answer:
-9 -72r
Step-by-step explanation:
-9 times 2 is -9
-9 times 8r is -72r
Because we don't have any set numbers for x or y, I believe that the solution set for both equations are infinite.
