After solving the equation the value of x is -23, 25 in the equation 19+|x-1|=33
How to solve an equation?
To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
⇒ 9+|x-1| = 33
For positive case
⇒ 9+|x-1| = 33
⇒ (x-1) = 33 - 9
⇒ x - 1 = 24
⇒ x = 25
For negative case
⇒9+|x-1| = 33
⇒ -(x-1) = 33 - 9
⇒ -x + 1 = 24
⇒ - x = 23
⇒ x = -23

Maya bought 3 chicken wings for $8.80. If Maya spent $25.30, how many chicken wings did she buy?
Answer:
She bought 8.625 wings
Step-by-step explanation:
We can use a ratio to solve
3 x
------- = ----------
8.80 25.30
Using cross products
3 * 25.30 = 8.80x
75.9 = 8.80x
Divide each side by 8.8
75.9/8.8 = 8.8x/8.8
8.625 = x

A rental car company charges $37.93 per day to rent a car and $0.11 for every mile driven. Taylor wants to rent a car, knowing that:
She plans to drive 50 miles.
She has at most $300 to spend.
Which inequality can be used to determine dd, the maximum number of days Taylor can afford to rent for while staying within her budget?
5.5d + 37.93 ≥ 300
5.5 + 37.93d ≤300
5.5 + 37.93d ≥ 300
5.5d + 37.93 ≤ 300
The inequality [tex]5.5+37.93d\leq300[/tex] should be used to calculate the number of days.
What is an inequality?
The relationship between two non-equal expressions, denoted by a symbol such as 'not equal to, 'greater than' or 'less than' is known as inequality.
She drives 50 miles and per mile it costs $0.11.
So, for 50 miles, cost = 50 x $0.11 = $5.5

Find the percent increase or decrease from 200 to 460.
57% increase
130% decrease
57% decrease
130% increase
The percent increase from 200 to 460 is 130% increase
How to find the percent increase or decrease?The numbers are given as
200 and 460.
460 is greater than 200
So, the percentage is an increment
The percentage increment is then calculated as
Percentage = (Final value - Initial value)/Initial value * 100%
Substitute the known values in the above equation
Percentage = (460 - 200)/200 * 100%
Evaluate the difference
So, we have
Percentage = 260/200 * 100%
Evaluate the quotient
So, we have
Percentage = 1.3 * 100%
Evaluate the product
So, we have
Percentage = 130%
Hence, the percent increase from 200 to 460 is 130% increase

Given a focal length of a mirror and an object distance, you determine that s' < 0. from this you can conclude that:_________
The image seen in the compact mirror is not of the same size as seen in the plane mirror. This compact mirror is concave on one side and convex on the other side.
The size of the image as compared to the object is related to the magnification. The size of an object’s image is larger (or smaller) than the object itself by its magnification, The level of magnification is proportional to the ratio of and An image that appears to be double the size of the actual object would have magnification
The radius of curvature of a mirror is twice its focal length.

Write a recursive formula for each sequence. 1,4,9,16, . . . . . . .
The recursive formula for sequence 1,4,9,16, . . . is a(n) = 2 a(n-1) - a(n-2) + 2
The recursive formula of a sequence is a formula that relates the nth term of the sequence with the preceding term(s), (n-1)th, (n-2)th, and so on.
The given sequence is: 1,4,9,16, . . .
So, we must ask ourselves:
How can we get 4 from 1?
How can we get 9 from 4 and 1?
and so on.
Notice that:
4 = 1 + 3
9 = 4 + 5
16 = 9 + 7
Notice that the differences (3, 5, 7) increase by 2.
Therefore, we can write:
4 = 1 + 3
= 1 + (1 - 0) + 2
9 = 4 + (4 - 1) + 2 (9 is a(3), and 4 is a(2))
a(3) = a(2) + a(2) - a(1) + 2
= 2 a(2) - a(1) + 2
16 = 9 + (9 - 4) + 2
a(4) = a(3) + a(3) -a(2) + 2
a(4) = 2 a(3) - a(2) + 2

A line y=mx+b is translated using the vector . Write the equation of the translated line. What is the value of the y -intercept?
The found value are-
Equation of the translated line: y = mx − am + 2b.The value of the y -intercept: 2b − am.What is general form of straight line?A straight line's general equation is y = mx + c, in which m is the gradient and y = c is the value at which the line intersects the y-axis. This number c is known as the y-axis intercept.
Now, as per the given question;
The general equation of the line is given as;
y = mx + b
Each point (x,y) of the line is moved to the point (x+a, y+b) by the translation:
(x,y) ---> (x+a, y+b)
We find the original line's x and y intercepts:
Put y=0 in general equation of the line
⇒mx+b = 0
⇒x = −b/m
When, x=0
⇒y = m⋅0 + b
⇒ y = b
A, (0,b) and B( -b/m, 0)
We find the translational coordinates of the points A,B:
A(0,b) ---> A′ (0+a,b+b)
A(0,b) ---> A′ (a,2b)
And,
B( -b/m, 0) ----> B'( -b/m + a, 0 + b)
B( -b/m, 0) ----> B'( -b/m + a, b)
To find the equation of the line's translation, we use the points A and B ′:
m' = (2b - b)/[a - (-b/m +a)]
m' = b/(b/m)
m' =m
And,
y−yA' = m' (x−xA')
y−2b=m(x−a)
y=mx−am+2b
The translation of the line's x and y intercepts are:
Put x=0
⇒y = m⋅0−am+2b
⇒y = 2b−am
And, put y=0
⇒0 = mx−am+2b
⇒x = a - (2b/m)
Therefore, the equation of the translate line is found to be y = mx − am + 2b.
And, the value of the y-intercept is found to be 2b−am.

(-4x2-3x+6) + (6x2 - 2x + 1) = 2x2-5x + 7, the opposite of 2x2 + x-7 is -2x2 - X+ 7 and (-4x2+2x-1) - (-2x2 + 3x+6) = -2x-x - 7
1. (-4x2-3x+6) + (6x2 - 2x + 1)
= -4x2+ 6x2- 3x- 2x + 1+ 6
= 2x2- 5x + 7
Thus, adding gives us 2x2- 5x + 7 and thus (-4x2-3x+6) + (6x2 - 2x + 1) will be matched with the 5th equation.
2. opposite of: 2x2 + x-7
The opposite of 2x2 + x-7 can be found if we just reverse the signs of each of the term. This means that + becomes - and - becomes -

what is the inverse of the function y=5x+30?
The inverse of the function is y = ( 1/5 )x - 6.
An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Consider the function,
y = 5x + 30
To find the inverse of the function we interchange x and y then find the equation for y.
Therefore, after interchanging x and y:
x = 5y + 30
Subtracting 30 from each side of the equation.
x - 30 = 5y + 30 - 30
x - 30 = 5y
Now, dividing the whole equation by 5
( x - 30 ) / 5 = 5y / 5
y = ( 1/5 )x - 30/ 5
y = ( 1/5 )x - 6
Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

number of miles in a day at which the rental costs for Company A and Company B are the same.
The number of miles in a day at which the rental costs for Company A and Company B are the same will be 200 miles.
We are given that:
For Company A:
Fixed cost = $ 110
Variable cost = $ 0.20 per mile
For Company B:
Fixed cost = $ 70
Variables cost = $ 0.40 per mile
Let the number of miles in a day be x.
So, the equation for rental cost for company A will be:
Rental cost = 110 + 0.20 x
The equation for rental cost for company B will be:
rental cost = 70 + 0.40 x
Now, put both rental cost equal.
110 + 0.20 x = 70 + 0.40 x
0.40 x - 0.20 x = 110 - 70
0.20 x = 40
x = 40 / 0.20
