Answers
The algebraic expression that is equivalent to the expression (4x • 7)(5x • 9) is (4 • 5)(7 • 9)(x • x).
How to find equivalent expression?An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction etc.)
Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.
In other words, two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same
Hence, the algebraic expression that is equivalent to (4x • 7)(5x • 9) is as follows:
(4x • 7)(5x • 9) = (4 • 5)(7 • 9)(x • x)
(4x • 7)(5x • 9) = 1260x²
(4 • 5)(7 • 9)(x • x) = 1260x²

Step-by-step explanation:
There are 3 red marbles, and 2 blue marbles. Add them together, and you get 5. You want to know how likely it will be to pull out a red marble, so the chance is 3 out of 5 (3/5). To get a decimal, you divide 3 by 5, and you get 0.6, and to make it a percent, move the decimal to the right twice or do 0.6 *100 and you get 60%.

Step-by-step explanation:

The distance jumped by Chris in total would be as follows:
\(10\frac{5}{8}\)
Find the distance
Distance is denoted as the space that one covers from a particular place to the other.
Given that,
The distance jumped by Mark \(= 9\frac{3}{4}\) feet
The distance jumped by Chris \(= \frac{7}{8} + 9\frac{3}{4}\)
So,
The total distance covered by Chris would be:
\(= \frac{7}{8} + 9\frac{3}{4}\)
\(= \frac{7}{8} + \frac{39}{4}\)
\(=\) \(\frac{(7 + 78)}{8}\)
\(= \frac{85}{8}\)
\(=\) \(10\frac{5}{8}\)
Thus, \(10\frac{5}{8}\) is the correct answer.

A bag contains 6 batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select 3 batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected
Answers
Answer:
there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.
Step-by-step explanation:
The counting principle states that if there are n ways to do one thing and m ways to do another, then there are n x m ways to do both.
In this case, we want to determine how many ways we can select 3 batteries out of 6. Using the counting principle, we can break down the selection process into three steps:
Select the first battery. There are 6 choices for the first battery.
Select the second battery. There are 5 choices left for the second battery, since we've already selected one.
Select the third battery. There are 4 choices left for the third battery.
Using the counting principle, we can multiply the number of choices for each step to get the total number of ways to select 3 batteries:
6 x 5 x 4 = 120
Therefore, there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.

A garden table and a bench cost 670 combined. The garden table costs 80 less than the bench. What is the cost of the bench?
Answers
The bench costs $375, and the garden table costs $295. Together, they amount to $670, with the table being $80 cheaper than the bench.
Let the cost of the bench be x. Then the cost of the garden table is x-80. The sum of the costs of both items is $670. So we have the equation: x + (x-80) = $670.
Simplifying this, we get 2x - 80 = $670 + 80 2x = $750 x = $375. So the cost of the bench is $375. The garden table costs $375 - $80 = $295. A garden table and a bench cost $670 combined.
The garden table costs $80 less than the bench. To find the cost of the bench, we can use algebraic equations. Let the cost of the bench be x. Then, the cost of the garden table is x - 80.
The sum of both costs is $670. Using this information, we can form an equation: x + (x - 80) = $670. Simplifying, we get 2x - 80 = $670 + 80. Solving for x, we get x = $375.
Therefore, the cost of the bench is $375, and the cost of the garden table is $295.

Which sequence of transformations was applied to the parent tangent function to create the function m(x) = 2tan(3x+4)
Answers
The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.
To determine the sequence of transformations, let's break down the given function:
1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.
2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.
3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.
4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.
5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.
In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.
Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.
After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)
This example helps illustrate the effect of the transformations on the graph of the function.

Answers
Answer:

Step-by-step explanation:
2/3(x+6) = -18
multiply (x+6) by 2/3
2/3x + 4 = -18
subtract 4 from both sides
2/3x + 4 - 4 = -18 - 4
2/3x = -22
multiply by 3/2
2/3 x 3/2 x = -22 x 3/2
x = -33

so we basically simplify the equation to the form, which is simple to understand
2/3(x+6)=-18 then Reorder the terms in parentheses
+( + 0.66666666666667x+4)=-18 after that

Answers
The solution to the system of equations is x = 1 and y = -3.
To solve the system of equations using the substitution or elimination method, let's start with the substitution method.
Given equations:
y = 4x - 7
4x + 2y = -2
We'll solve equation 1) for y and substitute it into equation 2):
Substituting y from equation 1) into equation 2):
4x + 2(4x - 7) = -2
4x + 8x - 14 = -2
12x - 14 = -2
Now, we'll solve this equation for x:
12x = -2 + 14
12x = 12
x = 12/12
x = 1
Now that we have the value of x, we can substitute it back into equation 1) to find y:
y = 4(1) - 7
y = 4 - 7
y = -3
Therefore, the solution to the system of equations is x = 1 and y = -3.

(g) f(3x) = 36x² + 12x - 3.
(h) f(x+h) = 4x² + 8xh + 4h² + 4x + 4h - 3.
Evaluating functions:The concept used in this question is evaluating a polynomial function for different values of the input variable. To do this, we substitute the given value into the function in place of the input variable and simplify the resulting expression.
Here we have
The function f(x) = 4x² + 4x-3.
To find the values of functions can be done by replacing x
(a) f(0) = 4(0)² + 4(0) - 3 = 0 + 0 - 3 = -3
(b) f(4) = 4(4)² + 4(4) - 3 = 64 + 16 - 3 = 77
(c) f(-4) = 4(-4)² + 4(-4) - 3 = 64 - 16 - 3 = 45
(d) -f(x) = -[4x² + 4x - 3] = -4x² - 4x + 3.
(e) f(x+1) = 4(x+1)² + 4(x+1) - 3 = 4(x² + 2x + 1) + 4x + 4 - 3 = 4x² + 12x + 1.
(f) f(-x) = 4(-x)² + 4(-x) - 3 = 4x² - 4x - 3.
(g) f(3x) = 4(3x)² + 4(3x) - 3 = 36x² + 12x - 3.
(h) f(x+h) = 4(x+h)² + 4(x+h) - 3 = 4(x² + 2xh + h²) + 4x + 4h - 3
= 4x² + 8xh + 4h² + 4x + 4h - 3.
Hence,
The values of functions are
(a) f(0) = -3. (b) f(4) = 77.
(c) f(-4) = 45. (d) -f(x) = -4x² - 4x + 3.
