What is expression?In mathematics, an expression is a combination of numbers, symbols, and operations that represent a value or a quantity. Expressions can be simple, such as a single number or variable, or they can be complex, consisting of multiple terms and operations. Expressions can involve a variety of mathematical operations, including addition, subtraction, multiplication, division, exponents, and roots. They can also include parentheses, brackets, and other symbols to indicate the order of operations or to group terms together. Expressions are commonly used in mathematical equations and formulas, and they are also used in programming languages and computer science to represent calculations and algorithms.
Here,
1. There are many expressions with three numbers that have the same result as -3 + -10. Here are a few examples:
(-5) + 2
(-8) + 5
(-15) + 12
In each of these expressions, the sum of the three numbers is equal to -13, which is the same as -3 + -10.

[Use the inequality 0.35x + 0.99y + 0.59 ≤ 4]
Yes, because the total will be $3.27
Yes, because the total will be $1.93
No, because the total will be $4.27
No, because the total will be $5.93
Answers
Answer:
The answer to your question is A. Yes, because the total will be $3.27
0.35(2)+0.99(2)+0.59≤4.
Then you multiply: .35(2)=.70. .99(2)=1.98.
Then add: .70+1.98+.59=3.27, so yes she can since 3.27 is less than 4 :)

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average
of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of
the individual
The middle 40% of heights fall between what two values? Sketch the graph, and write the probability statement
Answers
The probability statement is written below:
P(62.8 ≤ X ≤ 69.2) = 0.4What is the probability statement?The middle 40% of heights fall between the 10th and 90th percentiles of the standard normal distribution.
The z-scores of the 10th and 90th percentiles are -1.28 and 1.28 respectively.
The heights in the given normal distribution are found using the formula:
X = μ + zσwhere
X is the height,μ is the mean height = 66 inchesσ is the standard deviation = 2.5 inchesz is the z-score.The height of the 10th percentile is:
X = 66 + (-1.28)(2.5)
X = 62.8 inches
The height of the 90th percentile is:
X = 66 + (1.28)(2.5)
X = 69.2 inches
Therefore, the middle 40% of heights fall between 62.8 inches and 69.2 inches and the probability statement will be P(62.8 ≤ X ≤ 69.2) = 0.4

A graph of the given piecewise-defined function is shown in the image below.
What is a piecewise-defined function?In Mathematics and Geometry, a piecewise-defined function simply refers to a type of function that is defined by two (2) or more mathematical expressions over a specific domain.
Generally speaking, the domain of any piecewise-defined function simply refers to the union of all of its sub-domains. By critically observing the graph of this piecewise-defined function, we can reasonably infer and logically deduce that it is constant over several intervals or domains such as x > 2 and x < -2.
In conclusion, this piecewise-defined function has a removable discontinuity.

Write two expressions that are equivalent to the expression -4y - 16
by factoring out a common factor.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Determining the first equivalent expression:
Given the expression
\(-4y-16\)
Rewrite 16 as 4 · 4
\(\:-4y\:-\:16=-4y-4\cdot \:\:4\)
Taking common factor -4
\(=-4\left(y+4\right)\)
Therefore,
\(\:-4y\:-\:16=-4\left(y+4\right)\)
Determining the first equivalent expression:
Given the expression
\(-4y-16\)
Rewriting -4y - 4y as -1 · 4y - 1 · 16
\(\:-4y\:-\:16=-1\:\cdot \:4y\:-\:1\:\cdot \:16\)
Taking common factor -1
\(=-1\left(4y+16\right)\)
Therefore,
\(\:-4y\:-\:16=-1\left(4y+16\right)\)

840 different numbers can be created selecting 4 of the digits from the number
How many different numbers can be created selecting 4 of the digits from the numberFrom the question, we have the following parameters that can be used in our computation:
Number = 8712395
Digits = 4
The count of digits in the number is 7
Using the above as a guide, we have the following:
First digit = any of the 7second digit = any of the remaining 6Third digit = any of the remaining 5Fourth digit = any of the remaining 4So, we have
Numbers = 7 * 6 * 5 * 4

Buying vs Leasing Given the below lease terms at a local car dealership, what is the total cash paid by the end of the lease when at signing the dealership required a down payment, security deposit, acquisition fee at signing and all the monthly payments paid? Length of lease 48 = months MSRP of the car = $29,750 Purchase value of the car after lease = $19,900 Down payment =$2,800 Monthly payment =$595 Security deposit =$575 Acquisition fee =$400
Answers
Down payment = $2,800
Security deposit = $575
Acquisition fee = $400
Total initial payment = Down payment + Security deposit + Acquisition fee
Total initial payment = $2,800 + $575 + $400 = $3,775
Total monthly payments = Monthly payment x Length of lease
Total monthly payments = $595 x 48 = $28,560
Total cash paid by the end of the lease = Total initial payment + Total monthly payments - Residual value
Residual value = Purchase value of the car after lease = $19,900
Total cash paid by the end of the lease = $3,775 + $28,560 - $19,900
Total cash paid by the end of the lease = $12,435
Therefore, the total cash paid by the end of the lease, including the down payment, security deposit, acquisition fee, and all the monthly payments, is $12,435.

Answer:
When multiplying, add the exponents, (example) remember if there is "7b" the exponent is one.
Multiply b^2 * b^3 = b^5 (add the exponent 2 + 3 = 5)
Multiply 7b * b^3 = 7b^4 (the exponent of 7b is one, add 1 + 3 for the exponent to become 4)
Multiply 4 * b^3 = 4b^3 (4 doesn't have a variable, the exponent will be 3)
b^2 * b*2 = b^4 (add exponents)
7b * b^2 = 7b^3 (add the exponents 1 + 2)
