negative
Step-by-step explanation:
here are the answers to the questions in order, hope this helps!
Answer:
6) 9
7) 9
8) 10
9) 13
10) negative
Step-by-step explanation:
6) The |#| means absolute value (the value of how far away a number is from 0). Any number in that position will be positive (e.g., |-9| is 9).
|-5|+4
5+4
9
--------------------------------------------------------------------------------------------------------------
7) A negative divided by a negative is always a positive.
-99/(-11)
99/11
9
--------------------------------------------------------------------------------------------------------------
8) This is a bit confusing. Anything within |#| must be solved before you change it into AVF (absolute value form).
|(-6)-4|
|-10|
10
--------------------------------------------------------------------------------------------------------------
9) Subtracting a negative makes it positive.
4-(-9)
4+9
13
--------------------------------------------------------------------------------------------------------------
10) 1 times -1 equals -1
2 times -2 equals -4
3 times -3 equals -9
And so on.
--------------------------------------------------------------------------------------------------------------

Answer:
question 1: it is between 8 and 9. question 2: option B.
Step-by-step explanation:
1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.
2. to solve this, we can take the square root of the numbers to begin.
the square root of 25 is 5 (because 5x5=25)
the square root of 16 is 4
20 is actually not squarable, so we can estimate that it is a little greater 4.
the answer would be √16, √20, 4.85, √25
it would be option b.
hope this helps!! :))
In a bag of marbles, the probability of randomly selecting a yellow marble is 0.3.
The probability of randomly selecting a blue marble is 1/4
Which of the following is true?
A. It is less likely a blue marble is selected than a yellow marble.
B. It is more likely a blue marble is selected than a yellow marble.
C. It is equally as likely a blue marble is selected as a yellow marble.
D. There is no way to compare the two probabilities since we do not know how many marbles are in the bag.
Answer:
A
Step-by-step explanation:
if you know about% and if it is a number like 3 we will say and if it is like .3 that means that it is 30 % to 1/4th of 100 is 25

What kind of symmetry does this figure have?
point
line
both line and point
neither
Answer:
line and point
Step-by-step explanation:
The kind of symmetry the figure given above posses is a line and point symmetry.
What is point symmetry?A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.
Given that;
The objects looks the same when viewed from opposite directions.
We know that;
A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.
Therefore, the figure given above has both point and line Symmetry.

WILL MARK BRAINLIEST Which table represents a relation with a domain of (-1, 2} and a range of (3,5)?
Answer:
C
Step-by-step explanation:
Second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.
What do you mean by domain and range of a function?
For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.
Given is a relation with a domain of (-1, 2) and a range of (3, 5)
It can be seen that second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.
Therefore, second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

Write each Quadratic function in standard form. The 2 picture is my notes to help with the answer.
Answer:
33) 4x² + 8x + 1
35) -2x² + 36x - 147
Step-by-step explanation:
#33: f(x) = 4(x+1) ² - 3
f(x) = 4(x+1) ² - 3
First Step: Multiply (x+1) (x+1)
(x + 1)² or (x+1)(x+1) is a one real double.
A one real double means that there is only one real solution
(x + 1) (x + 1) = x² + 2x + 1
Second Step: Multiply x² + 2x by 4
4(x² + 2x + 1) = 4x² + 8x + 4
Final Step: Put -3 in the Quadratic Function and do -3 + 4 to get your constant
4x² + 8x - 3 + 4
= 4x² + 8x + 1
#35: f(x) = -2(x - 9) ² + 15
First Step: Multiply (x - 9) (x - 9)
Remember, (x - 9) ² or (x - 9) · (x - 9) is a one real double, meaning that there is only one real solution.
(x - 9) (x - 9) = x² - 18x + 81
Second Step: Multiply by -2
-2 (x² - 18x + 81) = -2x² + 36x - 162
Final Step: Add the constant by 15 in the equation. (Hint: the constant is -162)
-2x² + 36x - 162 + 15
= -2x² + 36x - 147
This is how you convert the function into standard form. Hope this helps.

Factor the expression.
Answer:
1. -4a
2. -4
Step-by-step explanation:
The first problem is 4 x _ = -16a
So it has an a in it and we know 4 x 4 = 16 so it's 4a and its negative so -4a
The second problem is -4

12. A chemist has 40 mL of a solution that is 50% acid. How much water should he add to make
a solution that is 10% acid?
Total Amount x % Acid = Amount of Acid
Total Amount
% Acid
Amount of Acid
Original Solution
Water
New Solution
Answer:
Volume of pure Acid in -50- LITRES of the solution= 10- litres. Let “V”- litres of water be added, then
Therefore 10= (50+ V) x8/100 .
So 10= 4 + 8V/100
8V/100 = 10–4= 6
So V= 6 x 100/8= 600/8= 75- LITRES.
So on adding 75- litres of water to the acid solution, the percentage of acid drops to 8% .
Check: Percentage of acid in 125- LITRES of acid solution, which contain 10- LITRES if pure Acid
= 10/125 x 100= 8% .

A scatter plot is shown below. Which equation would best describe the line of best fit for the scatter plot?
y = 2x + 1
y = 2x
y = x + 1
y = -2x - 1 1
Answer:
Scatter plot with line of best fit of y equals 0.75x plus five.
The line of best fit is y = 0.75x + 5.
Choose the best representation for the slope.
The slope of the line of best fit shows that each additional minute, the distance increases by 0.75 feet.
The slope of the line of best fit shows that each additional minute, the distance decreases by 5 feet.
The slope of the line of best fit shows that each additional minute, the distance decreases by 0.75 feet.
The slope of the line of best fit shows that each additional minute, the distance increases by 5 feet.

The Composite figure is made up of a Triangle, and a trapezoid. What is the area of the composite figure?
Answer:
I DON'T KNOW the answer but hears the explanation.
Step-by-step explanation: So the total area of the composite shape is 30 + 20 = 50 cm². Note: An alternative method is to use the formula for the area of a trapezoid. Example 2 A circular shaped garden of radius 15m contains a square concrete region of side length 4m.
The area of the composite figure is,
⇒ 22 m²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
The Composite figure is made up of a Triangle, and a trapezoid.
Now,
Area of triangle is;
⇒ A = 1/2 × 3 × 4
⇒ A = 6 m²
And, Area of trapezoid is,
⇒ A = (a + b) × h/2
⇒ A = (10 + 6) × 2/2
⇒ A = 16 m²
Thus, The area of the composite figure is,
⇒ 6 + 16
⇒ 22 m²
