The equation of the line perpendicular to y = 2 / 3 x - 4 and passes through (6, -2) is y = - 3 / 2x + 7.
How to represent equation in slope intercept form?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slope of the lineb = y-interceptThe slopes of perpendicular lines are negative reciprocals of one another.
Therefore, the slope of the line perpendicular to y = 2 / 3 x - 4 is - 3 / 2.
Hence, let's find the line as its passes through (6, -2).
Therefore,
y = - 3 / 2 x + b
-2 = - 3 / 2(6) + b
-2 = -9 + b
b = -2 + 9
b = 7
Therefore, the equation of the line is y = - 3 / 2x + 7.

She used these steps.
Step 1 Find a pattern in the table.
The pattern is to divide the previous value by 4 when the exponent decreases by 1.
Step 2 Find the value of 4 Superscript negative 3.
4 Superscript negative 3 = StartFraction 1 Over 16 EndFraction divided by 4 = StartFraction 1 Over 16 EndFraction times one-fourth = StartFraction 1 Over 64 EndFraction
Step 3 Find the value of 4 Superscript negative 4.
4 Superscript negative 4 = StartFraction 1 Over 64 EndFraction divided by 4 = StartFraction 1 Over 64 EndFraction times one-fourth = StartFraction 1 Over 256 EndFraction
Step 4 Rewrite the value for 4 Superscript negative 4.
StartFraction 1 Over 256 EndFraction = negative StartFraction 1 Over 4 Superscript negative 4 EndFraction
The value of 4 Superscript negative 4 is negative StartFraction 1 Over 4 Superscript negative 4 EndFraction.
In the given table, Tasha observed a pattern in the powers of 4. When the exponent decreases by 1, the previous value is divided by 4. Using this pattern, she determined the values for 4 squared, 4 Superscript 1, 4 Superscript 0, 4 Superscript negative 1, and 4 Superscript negative 2.
To find the value of 4 Superscript negative 3, she divided the previous value (StartFraction 1 Over 16 EndFraction) by 4, resulting in StartFraction 1 Over 64 EndFraction.
Similarly, for 4 Superscript negative 4, she divided the previous value (StartFraction 1 Over 64 EndFraction) by 4, yielding StartFraction 1 Over 256 EndFraction.
Finally, to rewrite the value for 4 Superscript negative 4, she expressed it as negative StartFraction 1 Over 4 Superscript negative 4 EndFraction.
Therefore, the value of 4 Superscript negative 4 is negative StartFraction 1 Over 4 Superscript negative 4 EndFraction, which simplifies to StartFraction 1 Over 256 EndFraction

A popular restaurant has 48 tables. On each table are 3 different types of salsa. In one day, all of the tables are used for 9 different sets of customers. Which expression can be used to estimate how many containers of salsa are needed for all the tables in one day?
A 50 × 9
B 16 × 3 × 9
C 50 × 3 × 10
D 40 × 5 × 5
The expression to estimate the number of containers of salsa needed is: 48 × 3 × 9. none of the option is correct.
To estimate how many containers of salsa are needed for all the tables in one day, we need to consider the total number of tables and the number of salsa containers required for each table.
Given that there are 48 tables and each table has 3 different types of salsa, we can estimate the total number of containers needed by multiplying the number of tables by the number of salsa types.
However, we also need to account for the fact that there are 9 different sets of customers throughout the day. Each set of customers will use all the tables, so we need to multiply the estimated number of containers by the number of sets of customers to get an accurate estimation for the day.
Let's analyze the options provided:
A) 50 × 9: This option assumes there are 50 tables, which is incorrect based on the given information.
B) 16 × 3 × 9: This option assumes there are 16 tables, which is incorrect based on the given information.
C) 50 × 3 × 10: This option assumes there are 50 tables and 10 different sets of customers. Although the number of tables is incorrect, this option accounts for the number of salsa types and the number of sets of customers. However, it does not accurately represent the given scenario.
D) 40 × 5 × 5: This option assumes there are 40 tables and 5 different sets of customers. It also considers the number of salsa types. However, it does not accurately represent the given scenario as the number of tables is incorrect.
None of the options provided accurately represent the given scenario. The correct expression to estimate the number of containers of salsa needed for all the tables in one day would be:48 × 3 × 9

how to draw the 6th term .
To draw the 6th term, represent it visually within the context of the pattern or sequence from which it is derived.
To draw the 6th term, we need to understand the context or pattern from which the term is derived.
Drawing the term usually involves representing the elements or characteristics of the pattern in a visual form.
Without specific information about the pattern, we can provide a general approach to drawing the 6th term.
Identify the Pattern:
Determine the sequence or pattern from which the 6th term is derived.
It could be a numerical sequence, a geometric pattern, or any other pattern.
For example, if the pattern is a number sequence of multiples of 3, the first few terms would be 3, 6, 9, 12, 15, and so on.
Visualize the Pattern: Based on the identified pattern, visualize how the elements change or progress from term to term.
This could involve drawing a diagram, a graph, or any visual representation that captures the pattern.
Consider using a coordinate grid, a number line, or any other suitable visual aid.
Locate the 6th Term:
Use the information from the pattern and the visualization to determine the specific position or value of the 6th term.
In our example of multiples of 3, the 6th term would be 18.
Draw the 6th Term: Finally, represent the 6th term in your chosen visual form.
This could mean marking the position on a number line, plotting a point on a graph, or incorporating the value into a diagram.
Note that the specific method of drawing the 6th term will depend on the nature of the pattern and the context in which it is given.
Providing more details about the pattern would allow for a more accurate and specific visual representation of the 6th term.

3. So, only some rectangles have 2 pairs of parallel sides.
1. All rectangles are parallelograms.
2. Parallelograms have exactly 1 pair of parallel sides.
3. So, all rectangles have exactly 1 pair of parallel sides.
The correct statement about rectangles is:
1. All rectangles are parallelograms.
2. Parallelograms have exactly 1 pair of parallel sides.
3. So, all rectangles have exactly 1 pair of parallel sides.
A rectangle is a type of parallelogram that has additional properties. By definition, a rectangle is a quadrilateral with four right angles. This means that opposite sides of a rectangle are parallel. Since all four sides of a rectangle are right angles, it follows that a rectangle has exactly 1 pair of parallel sides.
Option 1 states that only some rectangles are parallelograms, which is incorrect. All rectangles are parallelograms because they have opposite sides that are parallel.
Option 2 states that parallelograms have 2 pairs of parallel sides, which is also incorrect. Parallelograms have exactly 2 pairs of parallel sides, not 4. A rectangle is a special type of parallelogram that has additional properties such as all angles being right angles.
Option 3 states that only some rectangles have 2 pairs of parallel sides, which is incorrect. All rectangles have exactly 1 pair of parallel sides, not 2. Having 2 pairs of parallel sides would make a shape a parallelogram, not a rectangle.
Therefore, the correct statement is that all rectangles are parallelograms and have exactly 1 pair of parallel sides. 1,2,3 are correct.
