Answer:
(4x – 5) – (-3x + 4) can be simplified by distributing the negative sign to the terms inside the parentheses:
(4x - 5) + (3x - 4)
We can then combine like terms by adding the coefficients of x and the constants:
7x - 9
Therefore, the expression that is equivalent to (4x – 5) – (-3x + 4) is 7x - 9.

0.09
0.18
0.27
0.36
0.45
0.54
0.63
Answer:
One pattern that can be observed in the repeated table is that each number is obtained by adding 0.09 to the previous number.
Step-by-step explanation:
For example, to get from 0.09 to 0.18, we add 0.09. To get from 0.18 to 0.27, we add 0.09 again, and so on. This pattern continues throughout the table, with each number being 0.09 greater than the previous number.
Part A - In the given table we can observe that there is a continuous table of 0.09 till 0.63.
Part B - The table is in the ‘Step by step explanation’
Step-by-step explanation:0.09 * 1 = 0.09 → 0.09 / 1 = 0.090.09 * 2 = 0.18 → 0.18 / 2 = 0.090.09 * 3 = 0.27 → 0.27 / 3 = 0.090.09 * 4 = 0.36 → 0.36 / 4 = 0.090.09 * 5 = 0.45 → 0.45 / 5 = 0.090.09 * 6 = 0.54 → 0.54 / 6 = 0.090.09 * 7 = 0.63 → 0.63 / 7 = 0.090.09 * 8 = 0.72 → 0.72 / 8 = 0.090.09 * 9 = 0.81 → 0.81 / 9 = 0.090.09 * 10 = 0.90 / 0.9 → 0.90 / 10 = 0.09 OR 0.9 / 10 = 0.09

Ix+1/2I=3 ( is is the absolute value symbols)
Answer:
x= 2.5 and -3.5
Step-by-step explanation:
To solve the equation Ix+1/2I=3, we can break it down into two cases: one where x+1/2 is positive, and one where x+1/2 is negative.
Case 1: x+1/2 is positive
In this case, the absolute value of x+1/2 is equal to x+1/2 itself. So we can rewrite the equation as x+1/2=3. To solve for x, we subtract 1/2 from both sides: x=3-1/2. Simplifying further, we have x=2.5.
Case 2: x+1/2 is negative
In this case, the absolute value of x+1/2 is equal to -(x+1/2). So we can rewrite the equation as -(x+1/2)=3. To solve for x, we first distribute the negative sign: -x-1/2=3. Then, we add 1/2 to both sides: -x=3+1/2. Simplifying further, we have -x=3.5. To isolate x, we multiply both sides by -1: x=-3.5.
So, the solution to the equation Ix+1/2I=3 is x=2.5 and x=-3.5.

She claims that the new box must cost less than the original box. Explain why your co-worker's claim is incorrect. Include all necessary work to support your answer.
pls help
Answer:
Original box costs less than the new box.
Step-by-step explanation:
A). original box has a surface are of 216 sq in
2(10x6)+2(6x3)+2(10x3) = 216sq in
216sq in/144sq in = 1.5sq ft
1.5 sq ft x .22 = .33 per sq ft
B) new box has a surface area of 434 sq in
2(15x11) + 2(11x2) + 2(15x2) = 434 sq in
434sq in/144 sq ft = 3.01sq ft
3.01 sq ft x .15 = .45 per sq ft
The table shows the average depths of several lakes.
a. Identify the outlier in the data set.
b. Determine how the outlier affects the mean, median, mode, and range of the data.
c. Tell which measure of center best describes the data with and without the outlier.
a. The outlier in the data set is Crater lake with a depth of 1,148 feet.
b. The outlier has a significant effect on the mean and range of the data but no effect on the median and mode.
c. The median and mode are measures of center that are less influenced by outliers, so they best describe the data with or without the outlier.
What does outlier means in Statistics?An outlier is a single data point that deviates significantly from the average value of a set of statistics. Outliers are exceptions that exist outside of individual population samples.
How does outlier affects the mean, median, mode, and range of the data?The mean is heavily influenced by outliers, so the outlier in this case increases the mean depth of the lakes. The range is the difference between the highest and lowest values, so the outlier also increases the range.
Which measure of center best describes the data with and without the outlier?Without the outlier, the median depth is 33.5 feet, which is closer to the majority of the depths in the data set. Therefore, the median is the best measure of center for this data set without the outlier. With the outlier included, the median depth is still 43 feet, and the mode is also 43 feet, so either measure could be used to describe the center of the data set.

WILL GIVE BRAINLIEST! PLEASE HURRY!!Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples’ ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.
Look at the attachment.
Determine how many texts a 16 year old would send based on the trend line equation for both Keiko and Eric. Round to the nearest whole number.
Keiko = 76, Eric = 100
Keiko = 66, Eric = 64
Keiko = 70, Eric = 46
Keiko = 96, Eric = 100
Answer:
Step-by-step explanation:
For Keiko's trend line equation, we have t = 0.95a + 59. Plugging in a = 16, we get t = 0.95(16) + 59 = 74.2. Rounding to the nearest whole number, we get t ≈ 74.
For Eric's trend line equation, we have t = 0.55a + 90. Plugging in a = 16, we get t = 0.55(16) + 90 = 98.8. Rounding to the nearest whole number, we get t ≈ 99.
Therefore, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation. So, the answer is Keiko = 74, Eric = 99.
The solution is, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
For Keiko's trend line equation,
we have t = 0.95a + 59.
Plugging in a = 16,
we get t = 0.95(16) + 59 = 74.2.
Rounding to the nearest whole number, we get t ≈ 74.
and, we have,
For Eric's trend line equation,
we have t = 0.55a + 90.
Plugging in a = 16,
we get t = 0.55(16) + 90 = 98.8.
Rounding to the nearest whole number, we get t ≈ 99.
Therefore, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation.
So, the answer is Keiko = 74, Eric = 99.

help me solve the following with each step explaining square binomial (4x-5y)²
To expand the square of the binomial `(4x-5y)²`, you can use the FOIL method or the binomial square formula:
Using FOIL:
(4x - 5y)² = (4x - 5y)(4x - 5y) (writing out the square as a multiplication of the binomial by itself)
= 16x² - 20xy - 20xy + 25y² (using the FOIL method)
Simplifying:
= 16x² - 40xy + 25y²
Using the binomial square formula:
(4x - 5y)² = (4x)² - 2(4x)(5y) + (5y)² (formula: (a - b)² = a² - 2ab + b²)
= 16x² - 40xy + 25y²
Thus, the expanded form of the binomial `(4x-5y)²` is `16x² - 40xy + 25y²`.
Answer:
i do not know where the following is but here.
Step-by-step explanation:
To square the binomial (4x-5y)², we can use the formula:
(a - b)² = a² - 2ab + b²
In this case, a = 4x and b = 5y. So, we have:
(4x - 5y)² = (4x)² - 2(4x)(5y) + (5y)²
Simplifying the terms inside the parentheses, we get:
= 16x² - 40xy + 25y²
Therefore, the square of the binomial (4x-5y) is equal to the trinomial 16x² - 40xy + 25y².
Each term in the trinomial is obtained by squaring the corresponding term in the binomial and then applying the formula for the cross-product (-2ab).
So, (4x)² = 16x², (5y)² = 25y², and (-2)(4x)(5y) = -40xy.
Therefore, (4x-5y)² = 16x² - 40xy + 25y².

6.25 inches
Step-by-step explanation:Fraction of an inch that is used to represent 3 miles = 3/4 inch (0.75 inch)
Number of miles that is used to represent 3/4 inch = 3 miles
Fraction of an inch that is used to represent 1 mile = 3/4/3 inch
= 0.75/3
= 0.25 inch
Number of inches that are used to represent 25 miles = 3/4/3 * 25
= 0.75/3 * 25
= 0.25 * 25
= 6.25 inches
So the length of the map = 6.25 inches
