Answer:
5 + x +3= 3x - 2x + 1
Step-by-step explanation:
Use the points (1, 15000) and (8, 1000) for the slope of the trendline
m = (1000 - 15000)/(8 - 1) = (-14000)/7 = -2000
y = -2000x + b
15000 = -2000(1) + b
15000 = -2000 + b
17000 = b
Equation
y = -2000x + 17000
Answer:
134
Step-by-step explanation:
This sequence is arithmetic because it's going up by sane number, 3. Hence, it also linear for the same reason. The equation is y=3x+(0th term). The 0th term is the one before the 1st term, 11, which would be 8.
So the equation to finc any xth term is y=3x+8.
Example, first term is 3(1)+8=11.
Example, second term is 3(2)+8=14.
Example, third term is 3(3)+8=17.
The 42nd term is 3(42)+8=126+8=134.
Answer:
36
Step-by-step explanation:
We need to find the LCM of the two numbers because we need to know the lowest number that 12 and 9 are both in.
12 × 1 = 12
12 × 2 = 24
12 × 3 = 36
12 × 4 = 48
9 × 1 = 9
9 × 2 = 18
9 × 3 = 27
9 × 4 = 36
We can see that 36 is the lowest number that occurs both in 12 and 9 so the blue and red light will both link at 36 seconds
