Answer:
a₈ = [tex]\frac{1}{78125}[/tex]
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
Here a₁ = 1 and r = [tex]\frac{1}{5}[/tex] , then
a₈ = 1 × [tex](\frac{1}{5}) ^{7}[/tex] = 1 × [tex]\frac{1}{78125}[/tex] = [tex]\frac{1}{78125}[/tex]
Are (2,9) and (-3,-6) both on the line y - 4x + 6? If not, find an equation for the line that does pass through both points.
Answer:
points doesn't lie in the given line.
Step-by-step explanation:
firmula for finding the equation of these points are
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} [/tex]
x1=2 , x2=-3, y1= 9 ,y2=-6
subtitute all values in formula
[tex] \frac{y - 9}{ - 6 - 9} = \frac{x - 2}{ - 3 - 2} [/tex]
[tex]y - 3x - 3 = 0[/tex]
if we put (2,9) and (-3,-6) in new equation then they will satisfy equation.so this is the equation where points lie in the line

2(s - 5) = 2 (s + 5)
2s - 10 = 2 s - 10
2s = 2s
0 = 0
Answer:
2(s + 5) = 2s + 10, not 2s - 10
2s - 10 = 2s + 10

is 2/3greater than 0.67
Answer:
0.67>2/3
Step-by-step explanation:
If you divide 2 by 3, you will end up with 0.6.
Now, you can compare the two numbers 0.6 and 0.67.
Solve for d. 2(d − 10) = 18 d =
Step-by-step explanation:

4x^2-12x=-9
Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0

Step-by-step explanation:
10xy^2-5by^2+2ax^2-abx =
5y²(2x -b) + ax(2x -b) =
(5y²+ax) (2x-b)
Answer:
10xy^2
Step-by-step explanation:
10xy ^ 2-5by ^ 2 + 2ax ^ 2-abx
(10xy^2-5by^2)+(2ax^2-abx)
=5y² (2x -b) + ax (2x -b)

In which quadrant would the point
(9.-10) be located?
a) Quadrant 1
b) Quadrant 2
c) Quadrant 3
d) Quadrant 4
Answer:
D
Step-by-step explanation:
Start with the 9. It goes to your right. It is on the plus x axis.
You are either in quad 1 or quad 4
We need the - 10 to decide which.
+ 10 would go up and that would mean quad 1
- 10 mean going down so you are in Quad 4

Find the equivalent equation that results from, halving both sides first and then subtracting
1 from both sides. Show each step. You do not have to solve the equation at the end,
Answer:
6x - 1 = 9
Step-by-step explanation:
1. first you have to divide every term in the equation by 2
12x/2 + 4/2 = 20/2
2. simplify
6x + 2 = 10
3. next you have to subtract one from both sides
6x + (2-1) = (10-2)
4. simplify
6x + 1 = 9
Which interval notation represents the set of all numbers greater than -2 and less
than or equal to 3?
Answer:
yes
Step-by-step explanation:
Answer:
(- 2, 3 ]
Step-by-step explanation:
parenthesis ( ) is used when the end value is not equal
brackets [ ] are used when the end value is equal
Here numbers are greater but not equal to - 2 and less than or equal to 3
(- 2, 3 ] ← is the appropriate interval notation

Jackie has two new puppies. One weights 5 9/16 pounds, and the other weighs 6 1/4 pounds. Find the difference in their weights.
Answer:big brrrrrrd
Step-by-step explanation:
yes
Answer:
11/16 pounds
Step-by-step explanation:
The difference between their weights can be found by subtracting 6 1/4 pounds from 5 9/16 pounds to find the difference. To do this we must transfer it from 1/4 to sixteenths which is 4 sixteenths. Then we subtract.
6 4/16
