Answer:
[-4, 0]
Step-by-step explanation:
You want the set -4 ≤ x ≤ 0 expressed using interval notation.
Interval notationIn interval notation, an interval is expressed as an ordered pair, with the first number of the pair being the lower end of the interval, and the second number being the upper end.
When the inequality symbol used to describe the interval is "less than" (<), the bracket used is a round bracket (parenthesis). When the symbol is "less than or equal to" (≤), a square bracket is used. The brackets need not be of the same kind.
When one end of the interval is an infinity (positive or negative), a round bracket is used.
ApplicationThe interval
-4 ≤ x ≤ 0
is written using the ordered pair ...
[-4, 0]
The number sequence x satisfying-4< x <0 is an interval containing -4,0 as well as all numbers between -4 and 0.
[-4, 0]
What is Interval Notation on a Graph?A graph for interval notation is created when we describe the solution set of an interval on even a number line.
How do you write interval notation?Intervals are represented in rectangular brackets as well as parentheses, and two numbers are separated by a comma. The two numbers are referred to as the interval's endpoints. The number on the left represents the smallest element or lower bound.
Briefing:Interval notation is a technique for representing any subset of the real number line. To write interval notation, we utilize different symbols depending on the type of interval.. For instance, the set of numbers x satisfying 1 x 6 is an interval containing 1, 6, and all values between 1 and 6.
According to the information provided:The ordered pair is used to write the interval -4 x 0.
[-4, 0].

How many solutions are the answer of this problem? 9x-7=3(3x+2)
The number of solutions in the equation 9x - 7 = 3(3x + 2) is 0
How to determine the number of solutions in the equation?The equation is given as
9x - 7 = 3(3x + 2)
Open the bracket in the above equation
So, we have
9x - 7 = 9x + 14
Subtract 9x from both sides of the equation
So, we have
-7 = 14
The above equation is false
Hence, the number of solutions in the equation is 0

Mark decided to make Christmas presents for his classmates. He bought 10 lb of two types of candies: caramel candies for $2.80 per pound and chocolate candies for $3.50 per pound.
Write a function f(x) that represents the total cost of the candy, where x is the weight of the less expensive candy.
Total cost of the candy is represented by the function f (x) is;
⇒ f (x) = $2.80x + $3.50y
Where, x is the weight of the less expensive candy (caramel candy)
and, y is the weight of chocolate candies.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Mark bought 10 lb of two types of candies to make Christmas present for his classmates.
Let x is the weight of the less expensive candy (caramel candy).
And, y is the weight of chocolate candies.
Now, The cost of caramel candies = $2.80x
And, The cost of chocolate candies = $3.50y
Hence, Total cost of the candy = $2.80x + $3.50y
Therefore, Total cost of the candy is represented by the function f (x) is;
⇒ f (x) = $2.80x + $3.50y
Where, x is the weight of the less expensive candy (caramel candy)
and, y is the weight of chocolate candies.

chan is filling a box with 1 inch cubes. he filled the bottom layer with 5x1 inch cubes long, and 4x1 inch cubes wide. The box is 6 inches tall.
Answer:
120 cubes will fill the box
Step-by-step explanation:
You want to know the number of 1-inch cubes it takes to fill a box that is 5 cubes long, 4 cubes wide, and 6 inches tall.
LayerTo cover the bottom of the box, Chan needs to make an array of cubes that has 4 rows with 5 cubes in each row. That layer will have ...
4 × 5 = 20 . . . . cubes per layer
VolumeEach layer occupies 1 inch of height, and the box is 6 inches high. The volume of the box will be filled with six of these layers. That will take this many cubes:
(6 layers) × (20 cubes/layer) = 6 × 20 cubes = 120 cubes
Chan will need 120 cubes to fill the box.

. If C lies between A and B on AB, then AC + CB = AB. What can you logically conclude about AB?
Answer: AB is twice the size of AC and twice the size of CB
Step-by-step explanation: "Lies between" means that it's in the middle. C is in the middle of A and B. A to C would be the same distance of C to B because C seperates the segments into 2 equal halves. AB is the whole segment including C, you could do AC + AC if you substituted it for the lengths and you would still get AB

4. The two triangles are similar by virtue of the AAA triangle congruence theorem as a result of the corresponding angles which have equal measures.
5. The length of segment CE to the nearest tenth is; 46.7 in.
What is the length of segment CE as required in the task content?4. The ∆CBD and ∆CAE are similar (congruent) following the fact that angle C is common to both triangles and the angles A and E have equal measures as E and D respectively by virtue of corresponding angles theorem. Ultimately, the two triangles; ∆CBD and ∆CAE are congruent since all three angle measures are the same in the triangles.
The corresponding angles in discuss is due to the fact that the lines ED and AE are parallel lines.
5. Also, upon establishing the congruence of the two triangles, it follows that the ratio of their corresponding sides is same for all three sides.
Therefore, we can establish that;
BD/AE = CD/CE
6/14 = 20/CE
CE = (14 × 20)/6
CE = 140/3
CE = 46.667 in.
Ultimately, the length of segment CE to the nearest tenth is; 46.7 in.

In the lab, Miguel has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as Solution B. Solution A is 12% alcohol and Solution B is 16% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 120 milliliters of pure alcohol? Number of milliliters of Solution B: X Ś
Miguel uses 300 mL Solution B and 600 mL Solution A.
What is termed as the percentages?A percentage is a relative value that symbolizes the hundredth part of any quantity.One percent (symbolized 1%) is one hundredth part; thereby, 100 percent symbolizes the entire amount as well as 200 percent clarifies twice the given amount.Let x represent the amount of Solution B used.
2x = the quantity of Solution A used.
Solution A is alcohol = 12%.
Solution B is alcohol = 16%.
Given that 12% = 0.12 and 16% = 0.16, we can calculate the following equation:
2x(0.12) + x(0.16) = 120 (Recall that pure alcohol has a concentration of 100% = 1.00.)
0.24x + 0.16x = 120
0.40x = 120
x = 300 mL
Thus, Miguel makes use of 300 mL of Solution B and 2(300) = 600 mL of Solution A.

f(0) = 5, f(7) = 1328, f(-5) = -460
Step-by-step explanation:
[tex]f(x) = 4x^3 - 7x + 5[/tex]
We should substitute the values in the brackets into the equation to find the function's value at that x point.
[tex]f(0) = 4(0)^3 - 7(0) + 5\\\to f(0) = 5[/tex]
[tex]f(7) = 4(7)^3 - 7 \times 7 + 5\\\to f(7) = 4 \times 343 - 49 + 5\\\to f(7) = 1328[/tex]
[tex]f(-5) = 4(-5)^3 - 7(-5) + 5\\\to f(-5) = 4 \times -125 + 35 + 5\\\to f(-5) = -460[/tex]

How to find the average rate of change from x=1 to x=3?On the given graph, we have the following function values
f(1) = 6
f(3) = 4
The average rate of change from x=1 to x=3 is then calculated as
Rate = [f(3) - f(1)]/[3 - 1]
This gives
Rate = [4 - 6]/[3 - 1]
