Answer:
y=7.5
Step-by-step explanation:
y=
2*1.5ˣ+3=
substitute 2 for x
2*1.5²+3=
2*2.25+3=
4.5+3
y=7.5
Of course not.
If the line rises higher as it goes from left to right,
then its slope ( 'm' ) is positive.
If it sinks lower as it goes from left to right,
then its slope ( 'm' ) is negative.
Answer:
1. Right: pointing downwards
Left: pointing upwards
2. Right: pointing upwards
Left: pointing upwards
3. Right: pointing downwards
Left: pointing upwards
4a. True
4b. True
Step-by-step explanation:
When the leading coefficient is negative the equation will either open downwards or the y-values will decrease as the x-values increase. The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.
I hope this helps :)
Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
