The value of x in the absolute value inequality is given as5 - 10|3x + 3| < 95 is all set of real numbers
How to determine the values of the absolute inequality?The absolute value inequality is given as
5 - 10|3x + 3| < 95
Subtract 5 from all sides of the absolute value inequality
So, we have
- 10|3x + 3| < 90
Multiply -1/10 to all sides of the absolute value inequality
So, we have
|3x + 3| > -9
This means that the value of x is all set of real numbers

Answer:
Step-by-step explanation:
Step 1: we write 23% in decimal form: 23%=0.23.Step 2: we find the multiplier. Since we're increasing by 23%, we add 0.23 to 1: 1+0.23=1.23.Step 3: we multiply 80 by the multiplier 1.23: 80×1.23=98.4
So that means your answer is 1.23
Let P=(-2,2), Q=(3,4), R=(-2,5) , and S=(2,-8) . What are the component forms of the following vectors? -5RS
The components of -5RS are {-20; 65}.
The components of a vector in a two-dimensional coordinate system are usually thought of as the x and y components. This can be expressed as V = (vx, vy). where V is a vector. These are part of the vectors generated along the axis.
Suppose an angle θ is formed between the vector V and the x component of the vector. A vector V and its x component (vx) form a right triangle if you draw a line parallel to the y component (vy).
Due to the trigonometric relationship
cos θ = adjacent side/hypotenuse = vx/V
sin θ = opposite side/hypotenuse = vy/V
where V is the magnitude of vector V.
So, the Component of -5RS is Given by:
-5RS = -5* {Sx - Rx; Sy - Ry} = {2 - (-2); -8 - 5} = -5*{4; -13}
-5RS = {-20; 65}

If (x+1) is a factor p(x)= x²+x+2 then find the value of X.
If (x+1) is a factor p(x)= x² + x + 2 then the value of x is -1.
What is a polynomial?An expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a nonnegative integral power
We have,
(x + 1) is a factor of p(x) = x² + x + 2
We need to find x.
Since (x + 1) is a factor of p(x) it should satisfy p(x).
x + 1 = 0
x = -1

log (5) - log (2x) = 1 => x = 0.2499, by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Now,
log(5) - (log (2x)) =1
=> log (5) - [log (2) + log (x)] = 1 (as log(ab) = log(a) + log (b))
=>log (5) - log (2) - log (x) = 1
=> log ([tex]\frac{5}{2}[/tex]) - log (x) = 1
=> 0.3979 - log (x) = 1
=> log (x) = 0.3979 - 1
Since, generally the base of log is 10, raising them to 10
=> [tex]10^{log_{10}x} = 10^{-0.6021}[/tex]
=> x = 0.2499
Hence, log (5) - log (2x) = 1 => x = 0.2499, by properties of logarithm.

How much interest does 2560 earn in 17 months at a rate of 5 1/8%? Round to the nearest cent
The interest that 2560 earns in 17 months at a rate of 5 1/8% is $185.9.
How to calculate the interest?In the fields of finance and economics, interest is the payment of a sum over and above the principal amount to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. It is not the same as a fee that the borrower might pay to the lender or another entity.
Principal = $2560
Time = 17 months = 1.417 years
Rate = 5.125%
Therefore, the Interest will be:
= (Principal × Rate × Time) / 100
= (2560 × 1.417 × 5.125) / 100
= $185.9
Therefore, the interest that 2560 earns in 17 months at a rate of 5 1/8% is $185.9.

Write each expression in simplest form. (-32y¹⁵)¹/₅
The simplest form of the expression is determined by solving the fractional exponent.
If an exponent of the base (number) is expressed in a fraction, it is called a fractional exponent. In an expression say x^1/y, 1/y is the fractional exponent. Fractional exponent represents the power and root together.
In the given expression, the base term is -32y^15, while the exponent is 1/5.
Since, (ab)^m=a^mb^m
Hence, (-32y¹⁵)^¹/₅=(-32)^1/5*(y^15)^1/5
When a base number has a negative sign, and the power is an odd number, the negative sign is extracted.
(-32)^1/5*(y^15)^1/5=-(32)^1/5*(y^15)^1/5
Since, (a^m)^n=a^m*n
-(32)^1/5*(y^15)^1/5=-32^1/5y^15*1/5
As 32=2*2*2*2*2=2^5
The expression becomes.
-(2^5)^1/5*(y^15^)1/5
Multiplying the powers,
-(25)^1/5*(y^15)^1/5=-(2^5*1/5)(y^15*1/5)=-2y^3
The simplest form of expression is (-32y¹⁵)^¹/₅ is -2y^3.

The measure of a side of a square is x units. A new square is formed with each side 6 units longer than the original square's side. Write a simplified expression to represent the area of the new square.
Answer:

The new square's side can be algebraically expressed as [tex]x + 6[/tex], as we know it's 6 units longer than the previous square with side length [tex]x[/tex].
Therefore, its area would be:

Mrs Chua has a bag of sweets for some children. If each child gets 8 sweets, there will be 3 sweets extra. If she gives each child 9 sweets, there will be 2 sweets short. Find the extra number if sweets Mrs Chua needs to buy in order for each child to get either 8 or 9 sweets
Answer:
38
Step-by-step explanation:
It is clear that the number of sweets that should be bought so that each child can get either 8 or 9 sweets should be divisible by both 8 and 9
This is called the LCM or least common multiple of 8 and 9
Since 8 and 9 have no divisors in common LCM of 8 and 9 is 72 so 72 is the minimum number of sweets to buy so that there are no leftovers if each child gets 8 or 9 sweets
Let's compute the number of sweets that were bought the first time. Let the number of children be X
Since each child got 8 sweets and 2 were left over, the total of sweets must be 8X + 2
If each child were to get 9 sweets each then there would be 2 sweets short
This can be written as 9X -2 for the total number of sweets
Since these have to be equal,
9X - 2 = 8X + 2
Add 2 to both sides:
9X - 2 + 2 = 8X +2 + 2
9X = 8X + 4
Subtract 8X from both sides
9X - 8X = 8X - 8X + 4
1X = 4
==> X = 4
So number of children is 4
Total number of sweets bought
= 8 x 4 + 2 = 34
or
= 9 x 4 - 2 = 34
Therefore number of extra sweets to be bought = 72 - 34 = 38
