Answer:
The domain is[ -3, ♾)
Step-by-step explanation:
The graph above shows the graph of it parent function,
[tex]y = \sqrt{x} [/tex]
It includes x=0 because 0 is a perfect square.
Now consider the transformed function
[tex] \sqrt{x + 3} [/tex]
There is two ways to solve this:
Way#1. Algebra.
Remeber that we can't take the square root of a negative number.
(i.e We can but it isn't graphable on a Cartesian coordinate plane).
We can take the square root of 0 so we must set the number in the radical equal to 0.
[tex]x + 3 = 0[/tex]
[tex]x = - 3[/tex]
We include the point at x=-3, so we put a [ in front of -3. This number can accept any number as we approach positive infinity. So the domain is

Step-by-step explanation:
|-3| = 3 and |3| = 3 to
Answer:
2 integers at a time will be able to have the same absolute value. This is because integer can be both positive and negative, while absolute value always remains positive:
The absolute value of both 2 and (-2) is 2.
Latisha’s friend Brandee forgot to make up a test and had these scores: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and . 85% Homework Help ✎
Calculate Brandee’s mean. (Refer to the glossary in the eBook if you do not remember how to do this.) Does this average score really represent her abilities? Why or why not?
Brandee persuaded her teacher, Ms. Juarez, to allow her to make up the missed test. Brandee received a . Calculate her new mean.
What difference did the score make? Does this new mean represent Brandee’s ability more accurately?
Using mean and outlier concepts, it is found that:
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.--------------------------
The mean of a data-set is the sum of all it's values divided by the number of values.In this question, the data-set is Brandee's grades, that is: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and 85%.--------------------------
There are 8 grades.Thus, the mean is:
[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 0 + 85}{8} = 74.5[/tex]
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.
--------------------------
Supposing her grade on the make up test was of 90%, the new mean will be of:[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 90 + 85}{8} = 85.75[/tex]
Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.

The triangles are congruent with SSS postulates. Then the correct option is D.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Two triangles are shown.
The SSS postulate is one of the ways to prove that two triangles are congruent. SSS stands for "side-side-side," and it states that if three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent.
The corresponding sides of the triangle will be equal. Then the triangles are congruent with SSS postulates.
Thus, the correct option is D.

The metric system is based on powers of 10. For example, one kilometer is equal to
1,000 meters or 103 meters. Write each measurement in meters as a power of 10.
a. hectometer (100 meters)
b. megameter (1,000,000 meters)
c. gigameter (1,000,000,000 meters)
d. petameter (1,000,000,000,000,000 meters)
Step-by-step explanation:
1000 meters is 10³ meters (just to correct the typo).
a. 100 meters = 10² meters
b. 1000000 meters = 10⁶ meters
c. 1000000000 meters = 10⁹ meters
d. 1000000000000000 meters = 10¹⁵ meters
in other words, the exponents are simply counting the numbers of zeros.

Answer:
A = -8
B = 27
X = 6
y = 3
z = 9
Step-by-step explanation:
hope that helps
Answer:
Below in bold.
Step-by-step explanation:
A = (-2)^3 = -8.
B = (3)^3 = 27.
j^(3*3) = j^9 and j^(1*3) = j^3
j^9 / j^3 = j^6
So x = 6.
y = 3.
m^(3 * 3) = m^9.
z = 3*3 = 9.

Answer:
Joshua's Savings = $575
Step-by-step explanation:
If the total amount is $925 and you added $350 to x (Josh's Savings) than all we have to do is subtract the $350 from the $920 to solve for x,...
$925 - $350 = $575

When eating out, it is customary to tip your server at least 15% of the cost of your meal. The graph shows a 15% tip, t, for a meal that costs m dollars.
Each of the following sets of numbers represents dollars. Assuming the graph is correct, which set of numbers is most appropriate to label the seven tick marks along the vertical axis (15% tip)?
Question 5 options:
15, 30, 45, 60, 75, 90, 105
1.50, 3, 4.50, 6, 7.50, 9, 10.50
5, 10, 15, 20, 25, 30, 35
10, 20, 30, 40, 50, 60, 70
Answer:
1.50, 3, 4.50, 6, 7.50, 9, 10.50
Step-by-step explanation:
The x axis represents the amount of money the meal (without tip) costs.
The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.
So the question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50...
So 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct!
Hope this helps, let me know if you need further or better explanations!
The set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.
What is graphical representation?The term "graphical representation" refers to the use of charts and graphs to visually display, understand, and explain numerical data, functions, and relationships.
The x-axis represents the amount of money the meal (without tip) costs. The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.
The question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50.
Then 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct.
Therefore, the set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.

Members of a baseball team raised $1781.25 to go to a tournament. They rented a bus for $1063.50 and budgeted $65.25 per player for meals. Write and solve an equation which can be used to determine x x, the number of players the team can bring to the tournament.
Answer:x=11
65.25x + 1063.50= 1781.25
To solve this equation, subtract the rental cost of the bus to get $717.75.
Now the equation should be 65.25x= 717.75
Divide both sides by 65.25, and you should get that x = 11. That’s your finally answer!
