Answer:
-11[tex]c^{2}[/tex] - 4c
Step-by-step explanation:
You have to distribute the -c to both of the numbers in the parentheses, so the eleven would become negative, and c multiplied by c is c squared. The positive 4 becomes negative 4, and 4 times c is 4c. Hope that helps!

How many boxes of cereal can you buy with $38.45 if one box costs $7.69?
Answer:
5 boxes
Step-by-step explanation:
1 Box = 7.69
38.45/7.69 = 5
Answer:
5 cereal boxes
Step-by-step explanation:
If we know that one box is $7.69 and we have $38.45, we can make the expression: 38.45/7.69 (because we want to find the amount of boxes we can buy)
38.45/7.69 = 3845/769 = 5
You can buy 5 cereal boxes

Answer:Tables are used to organize exact amounts of data and to display numerical information. Tables do not show visual comparisons. As a result, tables take longer to read and understand. It is more difficult to examine overall trends and make comparisons with tables, than it is with graphs.
Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time.
Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories or groups. Bar graphs help us to see relationships quickly. However, bar graphs can be difficult to read accurately. A change in the scale in a bar graph may alter one's visual perception of the data.
Circle Graphs are used to compare the parts of a whole. Circle graphs represent data visually in the same proportion as the numerical data in a table: The area of each sector in a circle graph is in the same proportion to the whole circle as each item is to the total value in the table. Constructing an accurate circle graph is difficult to do without a computer. This is because you must first find each part of the whole through several elaborate calculations and then use a protractor to draw each angle. This leaves a lot of room for human error. Circle graphs are best used for displaying data when there are no more than five or six sectors, and when the values of each sector are different. Otherwise they can be difficult to read and understand.
Step-by-step explanation:

The measure of the supplement of an angle is 50 more than twice the measure of the complement. Find the measure of the supplement
Answer:
130°
Step-by-step explanation:
The measure of the supplement of an angle is 50 more than twice the measure of the complement. Find the measure of the supplement
Let us represent the Angle as x
An Angle + It's supplement = 180°
x + supplement = 180°
Supplement = 180° - x
Angle + Complement = 90°
Complement = 90° - x
The measure of the supplement of an angle is 50 more than twice the measure of the complement.
Supplement = 50 + 2(Complement)
Since = Supplement = 180° - x
Complement = 90° - x
Hence
180° - x = 50 + 2(90° - x)
180° - x = 50 + 180° - 2x
Collect like terms
-x + 2x = 50 + 180 - 180
x = 50°
Angle = x = 50°
We are asked to find the Measure for the supplement
Supplement = 180° - x
Supplement = 180° - 50°
= 130°
Hence, the measure of the supplement = 130°

What number is most likely to be expressed in scientific
notation?
A
The distance between your home and your school
B
The top speed that your parents' car can travel
С.
The amount of money it costs to buy a new car
D
The speed of light
Answer: D) The speed of light
The speed of light is approximately [tex]3 \times 10^8[/tex] meters per second.
[tex]3 \times 10^8 = 300,000,000[/tex]
In 1 second, a photon travels approximately 300 million meters
The other choices involve numbers that are well below the hundreds of million range, so scientific notation is not needed to shorten the number.
The speed of light is most likely to be expressed in scientific notation.
What is Scientific notation?Scientific Notation is the expression of a number n in the form a∗10b. where a is an integer such that 1≤|a|<10. and b is an integer too. Multiplication: To multiply numbers in scientific notation, multiply the decimal numbers. Then add the exponents of the powers of 10
Given, A data of numbers which shows the various data. For instance:
The distance between your home and your schoolThe top speed that your parents' car can travelThe amount of money it costs to buy a new carThe speed of light.Since, In 1 second, a photon travels approximately 300 million meters
The other choices involve numbers that are well below the hundreds of million range, so scientific notation is not needed to shorten the number.

A student finds a shiny piece of metal that she thinks is aluminum. In the lab, she determines that the metal has a volume of 245 cm3 and a mass of 612 g. Calculate the density. Is the metal aluminum?
Answer:
See below.
Step-by-step explanation:
The density = mass / volume
= 612 / 245
= 2.50 g/cm^3.
The literature states a density of 2.70 for the density of aluminium. The only other metal which is close to this value is strontium ( d = 2.64) which is a silvery colour so it might be that. One way to find out which it i s to see if the metal reacts with water. Aluminium does not while strontium does.
Solve for x.
−2(x+1/4)+1=5
Answer: The answer to this is x= -9/4
Answer:
[tex]\boxed {x = - \frac{9}{4}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex] :
[tex]-2(x + \frac{1}{4}) + 1 = 5[/tex]
-Use Distributive Property:
[tex]-2(x + \frac{1}{4}) + 1 = 5[/tex]
[tex]-2x + \frac{-2}{4} + 1 = 5[/tex]
-Reduce the fraction [tex]\frac{-2}{4}[/tex] to the lowest terms by canceling out [tex]2[/tex] :
[tex]-2x + \frac{-2}{4} + 1 = 5[/tex]
[tex]-2x - \frac{1}{2} + 1 = 5[/tex]
- Convert the integer [tex]1[/tex] to [tex]\frac{2}{2}[/tex] :
[tex]-2x - \frac{1}{2} + 1 = 5[/tex]
[tex]-2x - \frac{1}{2} + \frac{2}{2} = 5[/tex]
-Since both fractions [tex]-\frac{1}{2}[/tex] and [tex]\frac{2}{2}[/tex] have the same denominator, you add the numerators together:
[tex]-2x - \frac{1}{2} + \frac{2}{2} = 5[/tex]
[tex]-2x + \frac{1}{2} = 5[/tex]
-Change the integer [tex]5[/tex] to [tex]\frac{10}{2}[/tex] and subtract [tex]\frac{1}{2}[/tex] on both sides. Then, when both fractions have the same denominator, you subtract them, by subtracting the numerators:
[tex]-2x + \frac{1}{2} - \frac{1}{2} = \frac{10}{2} - \frac{1}{2}[/tex]
[tex]-2x = \frac{9}{2}[/tex]
-Divide by Multiplying [tex]2[/tex] and [tex]-2[/tex] :
[tex]\frac{-2x}{-2} = \frac{9}{2 (-2)}[/tex]
[tex]x = \frac{9}{-4}[/tex]
-Rewrite the answer:
[tex]x = \frac{9}{-4}[/tex]
[tex]\boxed {x = - \frac{9}{4}}[/tex]

It's asking if we can subtract any two functions and get the same result.
Let's say that f(x) = 2x+5 and g(x) = 7x-10
----------------------------
Subtracting f-g leads to...
f(x) - g(x) = ( f(x) ) - ( g(x) )
f(x) - g(x) = ( 2x+5 ) - ( 7x-10 )
f(x) - g(x) = 2x+5 - 7x+10
f(x) - g(x) = (2x-7x) + (5+10)
f(x) - g(x) = -5x + 15
----------------------------
Subtracting in the opposite order leads to...
g(x) - f(x) = ( g(x) ) - ( f(x) )
g(x) - f(x) = ( 7x-10 ) - ( 2x+5 )
g(x) - f(x) = 7x-10 - 2x-5
g(x) - f(x) = (7x-2x) + (-10-5)
g(x) - f(x) = 5x-15
----------------------------
We see that f-g is not the same as g-f
So generally, function subtraction is not commutative.
This is because subtraction is generally not commutative. Take for example how 7-2 = 5 and 2-7 = -5 are different results. The only time subtraction is commutative is when you're subtracting some number from itself (eg: 7-7 = 0).

f(4) is_______
f(x) = 4 when x is_________
Answer:
1/28Step-by-step explanation:
x = domain, f(x) = range
Look for matching numbers:
f(4) = 1/2f(x) = 4 when x = 8Answers:
f(4) is 1/2
f(x) = 4 when x is 8
====================================
Explanation:
Saying f(4) means f(x) when x = 4.
Locate 4 in the domain bubble. It points to 1/2 in the range bubble. This means x = 4 and y = 1/2 pair up. So f(4) = 1/2.
--------
When we're told f(x) = 4, we're given that y = 4 since y = f(x). So we need to find the x value that gets us to y = 4.
Locate y = 4 in the range. Trace the arrow in reverse to get to x = 8
f(8) = 4
A cosine function has been reflected over the x-axis and horizontally compressed by a factor of One-third
Which equation matches this description?
y = cosine (negative one-third x)
y = cosine (negative 3 x)
y = negative cosine (one-third x)
y = negative cosine (3 x)
Answer:The answer is D
Step-by-step explanation:
The correct answer for function y=cosx is y=negative cosine(3x).
What is function?A function is a combination of variables, and shows the relationship between one variable to another.
The given function is,
y=cos x,
When cos x is reflected over the x-axis,
y = -cos x
Further, horizontally compressed cos x by a factor of 1/3.
y =- cos(3x)
The correct answer is y=negative cosine(3x).

Answer:
It will take 7 months.
Step-by-step explanation:
Let m represent the number of months.
21 + 2m = 35
Then, isolate the variable.
2m = 35 - 21
