Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

Carlita planted 4 flowers in 6 minutes. About how many flowers can Carlita plant in 36 minutes?
Answer:
24
Step-by-step explanation:
[tex]\frac{4}{6} =\frac{x}{36}[/tex]
[tex]\frac{4}{6} *\frac{6}{6} =\frac{24}{36}[/tex]
[tex]x = 24[/tex]
Hope this helps and pls do mark me brainliest if you can:)
Answer:
24
Step-by-step explanation:
6*6=36, so she has 6 times as much time to plant with 36 minutes.
4*6=24, so she can plant 24 flowers in 36 minutes.
In a recent survey, 230 or 46% of the sample, said they usually ate fast food when they went out to eat. How many people were surveyed?

Which function has the same graph as x + y = 11?
A.
f(x) = -y + 11
B.
f(x) = -x + 11
C.
f(x) = x − 11
D.
f(x) = y − 11
Answer:
B. f(x) = -x + 11Step-by-step explanation:
y = f(x)
therefore
x + y = 11 → x + f(x) = 11 |subtract x from both sides
x - x + f(x) = 11 - x
f(x) = -x + 11
The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.
Therefore, the correct answer is:
B. f(x) = -x + 11
Here,
To find the function with the same graph as x + y = 11,
we need to isolate y in the equation to make it of the form y = f(x).
Given equation: x + y = 11
Subtract x from both sides of the equation:
y = 11 - x
Now, we have the equation in the form y = f(x).
so, we get, f(x) = -x + 11
i.e. The function which has the same graph as x + y = 11 is: f(x) = -x + 11
so, we have,
The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.
Therefore, the correct answer is:
B. f(x) = -x + 11

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression 2a+b when the value of a is 5 and b is 4 is equal to 14.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the expression 2a+b, whose values are needed to be calculated when the value of a is 5 and the value of b is 4. Therefore, the value of the given expression 2a+b can be written as,
2a + b
Substitute the value of a and b,
= 2(5) + 4
= 10 + 4
= 14
Hence, the value of the expression 2a+b when the value of a is 5 and b is 4 is equal to 14.

Step-by-step explanation:
You and a group of friends take turns planting 2 trees each at a campsite. After the first person plants 2 trees, there are 12 trees at the campsite. A. Write an equation for the nth term of the arithmetic sequence. Let n represent the position in the sequence and let an represent the number of trees. C. After 8 more people plant trees, how many trees are at the campsite?
Answer:
The equation for the nth term will be;
An = 10 + 2n
After the 9th planter ( 8 more than the initial one); number of trees will be 28
Step-by-step explanation:
After the first person plant two trees, there were 12 trees at the plant sites
What this mean is that initially, they were 12-2 = 10 trees at the plant site
The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;
An = 10 + 2n
Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters
So using the equation, n will be 9
So ; A9 = 10 + 2(9)
A9 = 10 + 18
A9 = 28

Answer:
Either- 200778.9263 or 81
Step-by-step explanation:
Type this into the calculator:
First: (1/9)^6= 1.881676423x10^-6
Then: 81^4= 43046721
Then multiply the two: (1.881676423x10^-6)x 43046721= 200778.9263
Or
Try this- type ((1/9)^6)x(81^4) into the calculator which comes out to 81
((1/9)^6)x(81^4)=81
