How do you solve this, by using substitution?!
Answer:
x = -2, y = -9
Step-by-step explanation:
You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.
y = 2x -5 will become
4x - 1 = 2x - 5
Add 5 to both sides
4x + 4 = 2x
Subtract 4x from both sides
4 = -2x
Divide both sides by -2
-2 = x
Now we plug this number into an equation to find y.
y = 4x - 1 becomes
y = 4(-2) - 1
Simplifying it, we have:
y = -8 - 1
y = -9

Mr. Roy was creating bundles for his classes. He had 20 pencils, 80 pens and 55 markers.
He wanted each bundle to contain the same number of pencils, pens and markers.
a) What is the largest number of bundles he could create without any left over?
Answer:
The largest number of bundles he could create without any left over is 5.
Each bundle to contain 4 pencils, 16 pens and 11 markers
Step-by-step explanation:
Pencils = 20
Pens = 80
Markers = 55
a) What is the largest number of bundles he could create without any left over?
Find the highest common multiple of 20, 80 and 55
20 = 1, 2, 4, 5, 10, 20
80 = 1, 2, 4, 5, 8, 10, 16, 20......
55 = 1, 5, 11, 55
The highest common multiple of 20, 80 and 50 is 5
Pencils = 20 / 5
= 4
Pens = 80 / 5
= 16
Markers = 55 / 5
= 11
The largest number of bundles he could create without any left over is 5.
Each bundle to contain 4 pencils, 16 pens and 11 markers

Jimmy owns a small engine repair business. The revenue, in dollars, can be modeled by the equation y = 420 + 72x, where x is the number of hours spent repairing small engines. The overhead cost, in dollars, can be modeled by the equation y = 24x² + 180 where x is the number of hours spent repairing bikes. After about how many hours does the company break even? Note: The phrase break even refers to the value where the two functions are equivalent.
Answer:
5 hours
Step-by-step explanation:
Given
[tex]y = 420 + 72x[/tex] --- Revenue
[tex]y = 24x^2 + 180[/tex] --- Overhead cost
Required
Determine the hours for break even
To do this, we simply equate both expressions as follows:
[tex]24x^2 + 180 = 420 + 72x[/tex]
Collect Like Terms
[tex]24x^2 - 72x + 180 - 420 = 0[/tex]
[tex]24x^2 - 72x -240 = 0[/tex]
Divide through 24
[tex]x^2 - 3x - 10 = 0[/tex]
Expand:
[tex]x^2 -5x + 2x -10 = 0[/tex]
Factorize:
[tex]x(x -5) + 2(x -5) = 0[/tex]
[tex](x + 2)(x -5) = 0[/tex]
[tex]x + 2 = 0\ or\ x - 5 = 0[/tex]
[tex]x = -2\ or\ x = 5[/tex]
But x can't be negative because it represents time.
So, x = 5 hours

What is the solution to the equation –3.5(x + 12) = –2x + 18?
Answer:
x = -4.36364
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3.5(x + 12) = -2x + 18
Step 2: Solve for x
Distribute 3.5: 3.5x + 42 = -2x + 18Add 2x on both sides: 5.5x + 42 = 18Isolate x term: 5.5x = -24Isolate x: x = -4.36364Answer:
The answer I arrived at was x = -4.364
Step-by-step explanation:
3.5(x + 12) = -2x + 18
=> multiply 3.5 by everything in parenthesis
3.5x + 42 = -2x + 18
=> subtract 18 from both sides
3.5x + 24 = -2x
=> subtract 3.5x from both sides
24 = -5.5x
=> divide both sides by -5.5
-4.364 = x

if there is a matrix, which is 3x8, and 3 columns are linear dependent, then can it be full rank? if not, what rank is it?
The matrix 3 x 8 is a full rank matrix.
Matrix:
Matrix are a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Full rank matrix:
The rank of a matrix is the maximum number of its linearly independent rows.
Based on that, A full rank matrix is one which has linearly independent rows or/and linearly independent columns.
Given,
There is a matrix, which is 3x8, and 3 columns are linear dependent
Her we need to check whether the matrix is full rank or not.
We know that, the matrix is 3 x 8,
And 3 column are linear dependent,
Based on the following condition,

What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved as follows:
8(2x + 7) = 6(x - 7) - 2
⇒ 16x+56 = 6x-42-2
⇒ 16x+56 = 6x-44
⇒ 16x-6x = -44-56
⇒ 10x = -100
⇒ x = -10

Which statements verify that the solution set to |x + 3| < 5 is –8 < x < 2? Check all that apply. Substituting a value into the inequality from the solution set, such as –2, will create a true statement. Substituting a value into the inequality from the solution set, such as 1, will create a false statement. Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. Substituting any value into the inequality will create a true statement.
