[tex]\begin{cases}3x+12&\text{if }x>-4\\0&\text{if }x=-4\\-3x-12&\text{if }x<-4\end{cases}[/tex]
Step-by-step explanation:
The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...
3x +12 < 0
x +4 < 0
x < -4 . . . . . makes the absolute value function change its argument's sign
Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.

Answer:
1 .4x2-9= 2x+3,2x-3
2 .16x2-1=4x-1,4x+1
3 .16x2-4=4(2x+1)(2x-1)
4 .4x2-1=(2x+1)(2x-1)
Step-by-step explanation:
16x² − 1 = (4x − 1)(4x + 1) ; 16x² − 4 = 4(2x + 1)(2x − 1); 4x² − 1 = (2x + 1)(2x − 1) ;
4x² − 9 = (2x + 3)(2x − 3)
16x² − 1 is the difference of squares. This is because 16x² is a perfect square, as is 1. To find the factors of the difference of squares, take the square root of each square; one factor will be the sum of these and the other will be the difference.
The square root of 16x² is 4x and the square root of 1 is 1; this gives us (4x-1)(4x+1).
16x² − 4 is also the difference of squares. The difference of 16x² is 4x and the square root of 4 is 2; this gives us (4x-2)(4x+2). However, we can also factor a 2 out of each of these binomials; this gives us
2(2x-1)(2)(2x+1) = 2(2)(2x-1)(2x+1) = 4(2x-1)(2x+1)
4x² − 1 is also the difference of squares. The square root of 4x² is 2x and the square root of 1 is 1; this gives us (2x-1)(2x+1).
4x² − 9 is also the difference of squares. The square root of 4x² is 2x and the square root of 9 is 3; this gives us (2x-3)(2x+3).

. Larry solved this equation. 3(2-3)= x Which representation could Larry have used to solve this equation?
Answer:
x = -3
Step-by-step explanation:
Given the expression solved by Larry as;
3(2-3) = x
We are to find the equivalent expression x
Using the distributive law;
3(2) - 3(3) = x
6 - 9 = x
-3 = x
Swap
x = -3
Hence Larry could use the distributive law to solve the expression

Answer:
45 cm
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
b = 3 + 2 = 5
A = 1/2(5)(6)
A = 15
Area of a rectangle:
A = bh
A = 12*2.5
A = 30
Combined:
30 + 15 = 45
The sailboat has 2 right angle triangles and a rectangle
First lets find the area of the rectangle then each one of the triangles
Area of rectangle = Length × Height
Area of rectangle = 12 × 2.5
Area of rectangle = 30 cm²
Now lets find the area of triangle on the right,
Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]
Area of triangle = 6 × 3 × [tex]\frac{1}{2}[/tex]
Area of triangle = 18 × [tex]\frac{1}{2}[/tex]
Area of triangle = [tex]\frac{18}{2}[/tex]
Area of triangle = 9 cm²
Now lets find the area of the triangle on the left,
Area of triangle = Height × base × [tex]\frac{1}{2}[/tex]
Area of triangle = 6 × 2 × [tex]\frac{1}{2}[/tex]
Area of triangle = 12 × [tex]\frac{1}{2}[/tex]
Area of triangle = [tex]\frac{12}{2}[/tex]
Area of triangle = 6 cm²
Now lets find the total area of the sailboat,
Total area = Area of rectangle + Area of triangle on the right + Area of triangle on the right
Total area = 30 + 9 + 6
Total area = 39 + 6
Total area = 65 cm²
Therefore the total area of the sailboat is 65 cm²

The measure of an angle is 39°. What is the measure of its complementary angle?
Answer:
51 degrees
Step-by-step explanation:
Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).
90 - 39 = 51
Answer:
51°Step-by-step explanation:
Complementary angles add to 90°.If one of them is 39°, then the other is:
90° - 39° = 51°Avery is going to invest $270 and leave it in an account for 20 years. Assuming the interest is compounded continuously, what interest rate, to the nearest hundredth of a percent, would be required in order for Avery to end up with $600?

Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
Answer:
The graph shows a relation and a function
Step-by-step explanation:
Because there is one value of y for every value of x, this is a relation and a function.
Answer:
relation because the x does not repeat
Determine if the two triangles are congruent. If yes, which theorem proves their congruence?
Answer:
Not congruent.
The Angle-Side-Side Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non included angle, then triangles are NOT NECESSARILLY congruent.

Answer:
A's coordinates are:
A. (-4, 3)
Step-by-step explanation:
Because the x always goes first,
So that will mean -4 will go first.
After you have -4 down, you will see that A's point on the graph is (-4, ?)
To answer the ?, you will have to check the y.
Because remember, The x-coordinate always comes first, followed by the y-coordinate.
So, it will be (-4, 3)
and 3 will be the fill in for y.
I hope this helps :)

Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.
Step-by-step explanation:
Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.
3w + 1 = 7 Subtract 1 from both sides
3w = 6 Divide 3 from both sides
w = 2

Q. A dice shows the numbers 1 through 12, with one number showing each time the die is rolled. What is the probability of rolling a 7?
Answer:
1/12
Step-by-step explanation:
The total number is 12 (assuming the dice would be rolled 12 times) 7 is a number in the range and it will appear once in the 12 rolls because each number shows each time. 1 (how many times 7 will show)/ 12(total number of rolls)
Probability of [tex]7[/tex] when a dice (showing numbers 1 throught 7) is thrown is equal to [tex]\boldsymbol{\frac{7}{12}}[/tex] as a dice is rolled.
Define probability.Probability refers to chances of occurrence of any event.
Value of probability lies in the interval [tex]\boldsymbol{\left [ 0,1 \right ]}[/tex]
Total number of numbers on a dice [tex]=12[/tex]
Probability is equal to number of favorable outcomes divided by the total number of outcomes.

Stephanie puts 30 cubes in a box. The cubes are inch on each side. The box holds 2 layers
with 15 cubes in each layer. What is the volume of the box?
Answer:
[tex] 11.25\: {in}^{3} [/tex]
Step-by-step explanation:
Since, box contains two layers of cubes and each layer has 15 cubes.
So, length = 15*1/2 in = 7.5 in,
width = 3*1/2 in = 1.5 in
height = (1/2 + 1/2) = 1 inch
Volume of box = lbh
= 7.5* 1.5 *1
= 11.25 cubic inches
To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? * answer to this problem hat is what i need
Answer:
7 1/2 quart of paint
Step-by-step explanation:
To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *
The above question is solved as:
3 1/4 quart + 1 2/4 quart + 2 3/4 quart
Lowest common denominator = 4
3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)
= 6 + ( 1 + 2 + 3/4)
=( 6 + 6/4) quart
= 6 + 1 2/4 quart
= 7 2/4 quart of paint
= 7 1/2 quart of paint
Therefore, Johan made 7 1/2 quart of paint
