Given:
Consider the given sequence is 9, 81, 729, 6561.
To find:
The common ratio.
Solution:
We have,
9, 81, 729, 6561
Here,
First term = 9
Second term = 81
Divide the second term by first term to get the common ratio.
[tex]r=\dfrac{81}{9}[/tex]
[tex]r=9[/tex]
Similarly,
[tex]\dfrac{81}{9}=\dfrac{729}{81}=\dfrac{6561}{729}=9=r[/tex]
Therefore, the common ratio is 9.

4. slope = -2; y-intercept = -1/2
5. slope = -3/4; y-intercept = -3
Answer:
Step-by-step explanation:
1. y = 1/4 x + 7
2. y = -3 x + 2/3
3. y = 2/3 x + 2/3
4. y = -2 x - 1/2
5. y = -3/4 x - 3
Georgia practiced for her dance recital for 3/4 of an hour on Monday, 3/8 of an hour on Tuesday, and 5/6 of an hour on Wednesday. How much longer did she practice on Monday than on Tuesday?
Answer: 22.5 minutes
Step-by-step explanation: On Monday Georgia practiced for 3/4 of an hour and on Tuesday she practiced for 3/8 of an hour. The difference between those two is 3/8 of an hour and when you take 3/8 of 60 minutes you get 22.5 minutes
Answer: 3/8 longer or 2 times longer or 22.5 minutes longer on Monday depending on the type of answer they want.
Step-by-step explanation: 3/8 longer or 2 times longer Explanation is: Gotta find common denominator Common denominator is 8 6/8 on Monday and 3/8 on Tuesday so difference of 3/8 or twice as long 22.5 Minutes Longer explanation is: 3/4 of an hour is 45 minutes (60/4=15x3=45) 3/8 of an hour is 7.5 minutes (60/8=7.5x3=22.5) So 45-22.5= 22.5 minutes longer on Monday. In fraction form its 9/40.

1.How do you know you have a direct variation in the
relationship between two quantities?
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

Find the value of x
12
5
X
Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13
~
Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²
The weight of a baby dog on day one is 5 kilograms. Every day, the dog grows an additional 0.1 kilograms. How heavy the dog is after 10 days?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The weight of the dog after 10 days is 5.9 kg.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Weight of the baby on day one = 5 kg
This can be written as,
1 day = 5 kg
The dog grows 0.1 kg each day.
This means,
On the 2nd day, we get,
2 days = 5 + 0.1
2 days = 5.1 kg
The expression for the weight of the dog on n days can be written as,
n days = 5 + (n -1) x 0.1 _____(1)
Now,
After 10 days we get,
n = 10
From (1) we get,
10 days = 5 + (10 - 1) x 0.1
10 days = 5 + 9 x 0.1
10 days = 5 + 0.9
10 days = 5.9 kg
Thus,
The weight of the dog after 10 days is 5.9 kg.

Answer:
o represent 1/3 on a number line, we divide the gap between O and A into 3 equal parts. Let T and Q be the points of division. Then, T represents 1/3 and Q represents 2/3, because 2/3 means 2 parts out of 3 equal parts as shown below. By using the same procedure, point O represents 0/3 and point A represents 3/3.

Shea wrote the expression 5(y+2)+4 to show the amount of money five friends paid for snacks at a baseball game.Which espression is equivalent to the one shea wrote?
Answer: B. 5 ∙ y + 5 ∙ 2 + 4
Step-by-step explanation:
The options are:
a. 5 + y + 5 + 2 + 4
b. 5 ∙ y + 5 ∙ 2 + 4
c. 5 ∙ y + 5 ∙ 4 + 4
d. 5 ∙ y + 5 + 2 + 4
To solve the question, we have to expand 5(y+2)+4. This will be:
= (5 × y) + (5 × 2) + 4
= 5 ∙ y + 5 ∙ 2 + 4
= 5y + 10 + 4
= 5y + 14
Solve the system of linear equations by substitution.
3x + y = -3 -2x + y =7
Answer:
(-2, 3)
Step-by-step explanation:
First solve one equation for y:
[tex]-2x+y=7\\y=7+2x[/tex]
Now we can substitute this equation into the other one:
[tex]3x+7+2x=-3[/tex]
Solve for x:
[tex]x=-2[/tex]
Now substitute this value into the equation [tex]y=7+2x[/tex]:
[tex]y=7+2x(-2)[/tex]
Solve for y:
[tex]7=3[/tex]
Now your solution is (-2,3)

What is the rate of change of the table shown?
Answer: rate of change = 2
===============================
Explanation:
Apply the slope formula. I'll use the first two columns as the two points, but you can use any two columns you want.
m = (y2-y1)/(x2-x1)
m = (9-5)/(3-1)
m = 4/2
m = 2
The slope is 2, so the rate of change is 2. Slope and rate of change describe the same thing. Each time x goes up by 1, y goes up by 2.
