The slope of g(x) is -3 and the g(x) is reflected across the x-axis
The table of values is
x f(x) = x g(x) = -3x
0 0 0
1 1 -3
2 2 -6
How to complete the blanks in the question?From the question, we have the definition of the functions to be
f(x) = x and g(x) = -3x
Also, we have the following x values from the blank table of values
x = 0, 1 and 2
Next, we calculate f(x) and g(x) at these x values
For the function f(x), the values are
f(0) = 0, f(1) = 1 and f(2) = 2
For the function g(x), the values are
g(0) = 0, g(1) = -3 and g(2) = -6
The next step is to calculate the slope and the transformation
Recall that
f(x) = x and g(x) = -3x
Generally, the form of a linear equation is
y = mx
Where m is the slope
This means that the slope of g(x) is -3
Lastly, the negative sign in g(x) = -3x implies that the graph is reflected across the x-axis or the y-axis

Simplify the following expressions by using the properties of exponents. Assume none of the denominators is zero.
a^3 (2a^2 + 4bc^4)^ 0
The simplified form of the expression is a³ which is calculated by using the properties of exponents.
Exponentiation is a mathematical operation that involves the base number (b) and the exponent (or power) number (n), and is represented as bⁿ. Its pronunciation is "b (raised) to the (power of) n." Exponentiation corresponds to repeated base multiplication where n is a positive integer; so, bⁿ is the result of multiplying n bases.
Typically, a superscript to the right of the base indicates the exponent. Then, bⁿ is referred to as "b raised to the nth power," "b (raised) to the power of n," "the nth power of b," "b to the nth power," or, most succinctly, "b to the nth."
The given expression is a³(2a² + 4bc⁴)⁰.
From the properties of exponents we know that:
a⁰ = 1
Therefore the value of the part of the expression (2a² + 4bc⁴)⁰ is 1
Therefore the total value of the exponential expression is a³

When we have a function and want to evalueate it for some "x", we just substitute every "x" with the value in parenthesis. So, to evaluate f(a + 2), we have x = a + 2, so we need to substitute every "x" in the function with a + 2:
[tex]f(a+2)=(a+2)^2-2(a+2)+1[/tex]Now, to simplify, we first need to use the distributive property on the second parenthesis and evaluate the binomial in the first:
[tex]f(a+2)=a^2+4a+4-2a-4+1[/tex]Now, we group the like-terms and add them:
[tex]\begin{gathered} f(a+2)=a^2+4a-2a+4+4+1 \\ f(a+2)=a^2+2a+1 \end{gathered}[/tex]For yhe other one, Let's do each term and then make the substraction:

We have to write 8.94 in fractional notation without simplification.
For decimal values, we can convert them to fractions taking into account the number of decimals they have.
In this case, 8.94 has two decimals. Then, we can multiply it by a fraction 100/100, as 100 has two zeros.
Then, we will get:
[tex]8.94\cdot\frac{100}{100}=\frac{8.94\cdot100}{100}=\frac{894}{100}[/tex]This works beacuse we multiply the number 8.94 by a number that will make it become an integer (without decimals). To keep the value of the fraction equal to the decimal number, we have to divide by the same factor (in this case, 100).
This fraction can be simplified.
Answer: the fractional notation, without simplification, of 8.94 is 894/100.
to find 24 times 17 i multiply 20 times 17 and add it to 4 times 17
Step-by-step explanation:
to find 24 times 17 i multiply 20 times 17 and add it to 4 times 17?
Yes, that is one way of doing it:
Your method:
20 × 17 = 340
4 × 17 = 68
340 + 68 = 408
The typical way of solving is:
24 × 17 = 408
Both return the correct answer.
Answer:
24 times 17 = 408
But if you multiply:
20 times 17 = 340 Then add that to:
4 times 17 = 68
340 + 68 = 408
You would get the same answer so this is correct!

Miss sheet,owner of the Bedspread shop knows his customers will pay no more than $145 for a comforter Misu wants a 40percent markup on selling price what is most that Misu can pay for a comforter?
The price that Misu can pay for a comforter based on the markup percentage is $103.57.
How to calculate the value?From the information, the Bedspread shop knows his customers will pay no more than $145 for a comforter Misu wants a 40 percent markup on selling price.
Let the selling price be represented as x. Based on the information given, this will be illustrated as:
x + (40% × x) = 145
x + 0.4x = 145
1.4x = 145
Divide
x = 145/1.4.
x = 103.57

6. Suppose the class takes a test and the following averages are obtained: mean = 80, median= 90, and mode = 70. Tom, who scored 80, would like to know if he did better than half the class. What is your response?
We know that the mean is 80, the median is 90, and the mode is 70. This means that the majority of students got an 80 on the test.
However, the median is 90, which means half of the class is below 90 where Tom's grade is placed.
Hence, he did not do better than half of the class.The elephants at the zoo eat 3 1/6 buckets of bananas each day. The zookeeper bought 6 1/3 buckets of bananas. How many days will the bananas last?
Write your answer as a fraction or as a whole or mixed number.
The bananas will last 2 days at the zoo (found by division).
According to the question,
We have the following information:
The elephants at the zoo eat [tex]3\frac{1}{6}[/tex] buckets of bananas each day. The zookeeper bought [tex]6\frac{1}{3}[/tex] buckets of bananas.
Now, first we will find the number of days taken in eating 1 bucket of bananas.
[tex]3\frac{1}{6}[/tex] buckets = 1 day
Now, we will convert this mixed fraction into simple fraction.
19/6 buckets = 1 day
1 bucket = 1/(19/6) days
1 bucket = 6/19 days
Now, we have the total number of buckets as [tex]6\frac{1}{3}[/tex].
Now, after converting this mixed fraction, we have:
19/3 buckets
1 bucket = 6/19 days
19/3 buckets = (6/19)*(19/3)
19/3 buckets = 2 days
2 is a whole number.
Hence, the given buckets of bananas will last 2 days.

What is an equation of the line that passes through the point (8,0)(8,0) and is parallel to the line x-4y=20x−4y=20?
The equation of the line that passes through the point (8, 0) is parallel to the line x - 4y = 20 is 1/4x - y = 2
Given,
The equation of the line: x - 4y = 20
The points which the line passes through, (x₁, y₁) = (8, 0)
We have to find the equation of the line parallel to the given line.
The formula for the slope intercept form:
(y - y₁) = m(x - x₁)
m is the slope of the line.
Lets find the slope of the line given.
x - 4y = 20
x = 20 + 4y
x - 20 = 4y
y = (x - 20) / 4
y = 1/4x - 5
Here, slope of the line is 1/4
Now, substitute the slope of the line and (x₁, y₁) in the slope intercept formula to get the equation of line parallel to the given line
(y - y₁) = m(x - x₁)
(y - 0) = 1/4(x - 8)
y = 1/4x - 8/4
y = 1/4x - 2
1/4x - y = 2
Therefore,
The equation of the line that passes through the point (8, 0) is parallel to the line x - 4y = 20 is 1/4x - y = 2

An artist wants to earn a revenue of $2700 by selling paintings for $30 each and sculptures for $45 each
The most appropriate choice for equation of line in slope intercept form x intercept = 90
y intercept = 60
Domain = {0, 3, 6, 9, ....., 90}
Range = {0 , 2, 4,...., 88}
What is equation of line in slope intercept form?
Equation of line in slope intercept form is written as y = mx + c, where m is the slope of the line and c is the y intercept of the line.
The distance from origin to the point where the line cuts the x axis is the x intercept and the distance of origin to the point where the line cuts the y axis is the y intercept.
Here,
Selling price of one painting = $30
Selling price of x paintings = $30x
Selling price of y sculptures = $45
Selling price of y sculptures = $45y
Total revenue = $(30x + 45y)
By the problem,
30x + 45y = 2700
a)
For x intercept, y = 0
30x = 2700
x = [tex]\frac{2700}{30}[/tex]
x = 90
x intercept is $90
For y intercept, x = 0
45 y = 2700
y = [tex]\frac{2700}{45}[/tex]
y = 60
y intercept is 60
b)
In 30x + 45y = 2700
Since x represents the number of paintings sold and y represents the number of sculptures sold, then x and y has to be integers.
If x = 0 , y = [tex]\frac{2700}{45}[/tex] = 60
If x = 3, y = [tex]\frac{2700 -90}{45} = 58[/tex]
If x = 6, y = [tex]\frac{2700 -180}{45} = 56[/tex]
