domain: (-3,3]
Orange: (-3,4]
decreasing: (-1.4)
increasing: (-3,-1)
negative: (-3,-2), (2,5]
positive: (-2,2)
Answer:
Only Option III, IV, VI are correct
Step-by-step explanation:
Domain is the set of values of x at which the function is defined. f(x) has defined values from x>-3 to x<=4, so the domain is (-3,4). Incorrect.
Range of the function is the set of all defined values of it. Here all values with y=f(x)>-3 and y<=3 are defined. So the range is (-3, 3}.
Decreasing and increasing parts of the funtion are shown in the graph when the y value goes up (positive slope) and vice versa.
The negative part of the function should be (3,-2) and (2,4] since (4, 5] is not defined and there is no indication for its negative-ness.

Answer:
(3,15)
Step-by-step explanation:
Rule 1
5x = y
Rule 2
x+12 = y
Set them equal
5x = x+12
Subtract x from each side
5x-x = x+12-x
4x= 12
Divide by 4
4x/4 = 12/4
x=3
5x=y
5*3 = y
15 = y
The solution is (3,15)
Given rules
y=5xy=x+12Equate and solve
5x=x+124x=12x=3Opt ion B is correct as no other contains 3 as x

Write the following number in
scientific notation.
0.05796
[? ][ ]
Answer:
[tex]0.05796 = 5.796 \times {10}^{ - 2} [/tex]
I hope I helped you^_^
Answer:
Step-by-step explanation:
Scientific notation is always written as a number between 1 and 9.999999. The number after the decimal is shown by a power of 10.
so 0.05796 = 5.796 * 10^-2
which means that the decimal was moved to represent a number less than one. That's the point of the minus sign. The two comes from the number of places you have to shift the decimal to get a number between 1 and 10.

Answer:
So for the sequence to work, the 5,3=18 would have to be changed to 5,3=23 in which it now fits and works to solve for x which is 4. There was a pattern of the numbers 4 and 5 that surfaced as the difference between each pairings sum total. The difference between each sum was alternating between the numbers 4 and 5, which equal 9 when added together. Which also helped me to form a chart of sorts that makes sense. My answer is typed above, that is the most stable conclusion that I could come to to make sense of the pairings that were listed.

On my last birthday I weighed 180 pounds. One year later my weight was decreased by x pounds, write the expression that gives my weight one year later.
Which is the action to take?
A) Multiplication
B) division
C) subtraction
D) addition
Answer:
c
Step-by-step explanation:
The expression that gives my weight one year later is (180 pounds - x pounds). Hence the subtraction action that gives weight one year later.
Given that;
On my last birthday, I weighed 180 pounds.
And, One year later my weight decreased by x pounds.
Now the equation to represent the weighed after one year,
180 pounds - x pounds
Hence we can use the subtraction action that gives weight one year later.
Therefore, the correct option is C.

Jeanne makes jewelry and has an idea for a new pair of earrings. She wants to make a sketch of her design, but only has a marker, a pencil, two pieces of paper, and a coffee mug. Use these items to construct the shape of the earring Jeanne is envisioning.
Step 1: Jeanne traced her coffee mug on her piece of paper. How might she use paper-folding to find the center of the circle? (2 points)
Step 2: Show how a second circle should be drawn in order to continue the construction. What can you say about the radii? Explain your work. (4 points)
Step 3: Describe the final steps in constructing the shape of the earring. Include a drawing.(2 points)
To complete her design Jeane will need to draw a smaller circle within the circle, and by using this circle and previous lines she can create the diamond design.
What should Jeane do after tracing the first circle?The second step is to fold the paper vertically and horizontally to determine the lines that divide it by half.
What is the third step?The third step is to draw a smaller circle within the first circle and make sure the circles are aligned in the center. This circle will have a smaller radius than the first one.
What is the final step?By using the previous lines Jeane should draw the desired design as shown in the image.

You go to the grocery store to buy milk and some eggs. Milk costs $3.67 and eggs cost $2.40. You want to make sure you have enough money. Estimate the cost of these two items to the nearest ones place.
Answer:
Step-by-step explanation:
Let's start by round 3.67. We look at the key digit which is 6 in this case. Since 6 is greater than 5, 3.67 will round up to 4.
The key digit in 2.40 is 4. 4 is not greater than 5, so we round down to 2.
2+4=6
Therefore, an estimate of these two items to the nearest ones place is $6.
Answer:
$2 for the eggs and $4 for the milk
Step-by-step explanation:
Since the eggs cost $2.40 and after the 2 you can see that there is a 4, " 5 or more we add one more, 4 or less just ignore", so it stays $2. However the milk costs $3.67, and here you can see that after the 3 there is a 4, so since it's more than 5 we change the estimated amount to $4.
I hope you understood, and I hope the answer is right :)
List all the digit even numbers that can be created by rearranging these number tiles
1
6
5
8
If your teacher is referring to four digit numbers with those tiles, where the tiles cant repeat, then we have 2 choices for the last slot (the units digit). Those two choices are: 6,8.
Recall that a number is only even if and only if the units digit is even (0,2,4,6,8).
Once a choice has been made for the units digit, we have...
3 choices for the thousands digit (whatever we didn't pick for the units digit)2 choices for the hundreds digit1 choice for the tens digitOverall, we have 2*3*2*1 = 12 different four digit numbers possible.
Those 12 numbers are:
value = 1658value = 1568value = 5168value = 5618value = 6158value = 6518value = 1856value = 1586value = 5186value = 5816value = 8156value = 8516This car traveled 3 miles per 1 min. Tell me how far the car will travel at 6 mins. Use a table to show your work .

Step-by-step explanation:
[tex]\sin(\theta + \phi) = 2\cos(\theta - \phi)[/tex]
Using the addition identity formulas, we can write
[tex]\sin{\theta}\cos{\phi} + \cos{\theta}\sin{\phi} = 2\cos{\theta}\cos{\phi} + 2\sin{\theta}\sin{\phi}[/tex]
Dividing both sides by [tex]\cos{\phi}[/tex], we get
[tex]\sin{\theta} + \cos{\theta}\tan{\phi} = 2\cos{\theta} + 2\sin{\theta}\tan{\phi}[/tex]
Dividing both sides by [tex]\sin{\theta}[/tex], we get
[tex]\tan{\theta} + \tan{\phi} = 2 + 2\tan{\theta}\tan{\phi}[/tex]
or
[tex]\tan{\theta}(1 - 2\tan{\phi}) = 2 - \tan{\phi}[/tex]
Rearranging the terms,
[tex]\tan{\theta} = \dfrac{2 - \tan{\phi}}{1 - 2\tan{\phi}}[/tex]

Use the converse of the Pythagorean Theorem to check whether a triangle whose sides are of lengths 11, 60, and 61 is a right triangle.
First square the lengths of the sides.
11^2 =
60^2 =
61^2 =
Answer:
yes a right triangle
Step-by-step explanation:
Using the converse of Pythagoras' theorem.
If the square on the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 61 and 61² = 3721 , then
60² + 11² = 3600 + 121 = 3721
Since 61² = 60² + 11² then the triangle is right.

Find the area and the circumference of a circle with radius 7 ft.
Answer:

Circumference is 43.96 ft
Step-by-step explanation:
Area is 2pir^2
Circumference is 2rpi
pi is about 3.14
A=2pi(7)^2
A= 98pi which is about 307.72 ft^2
C= 2(7)pi
C= 14pi which is about 43.96 ft

Select the correct answer. Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(x) - 3? A.It is the graph of f(x) translated 3 units down. B.It is the graph of f(x) translated 3 units to the left. C.It is the graph of f(x) where the slope is decreased by 3. D. It is the graph of f(x) translated 3 units up.
Answer: Choice A) translated 3 units down
Explanation:
x is the input while y = f(x) is the output. If we say f(x) - 3, then it's the same as saying y - 3. This means g(x) = f(x) - 3 subtracts 3 from each y coordinate of the points on f(x). This visually moves the entire f(x) curve down 3 units

Answer:
2 10/15 or 2 2/3 (simplified)
Step-by-step explanation:
To Multiply we need to get the same denominator for each fraction:
2 x 5 =10
3 x 5 =15
10/15
4/15 x 10/15 (or) 4 x 10 = 40/15
40/15 (also) = 2 10/15
2 2/3 (simplified version of 2 10/15)
