we know that given terms were i geometric progression.
which means common ratio is same between two consecutive terms .
here we have 8,40,200,1000.
we know that common ratio =second term/first term =40/8=5.
so each and every terms is multiplied by 5 to get next term for this series the term after 1000 is 5000 =1000*5.
in part b we have another series which is having common ratio of -2.
so we need to multiply with -2 to find next term.
80*(-2)=-160.
for part c the common ratio is -2 .
so we need to multiply with -2 *previous term =-2*16 =-32.
Answer:
Step-by-step explanation:
Parallel lines have same slope
<u>Given line is</u>
<u>Parallel line will be</u>
<u>Get the value of b using the point (-3, -2):</u>
- -2 = 1/3(-3) + b
- -2 = -1 + b
- b = -2 + 1
- b = -1
<u>So the line is</u>
Answer:

Answer:
y=-3x-2
Step-by-step explanation:
y=mx+b
y=-3x+b
y=3x-2
m is the slope, b is the y intercept
