Answer:
b = 12
Step-by-step explanation:
subtract eight from both sides to leave the b variable on the left
b/2 = 14 - 8
b/2 = 6
multiply by 2 on both sides to leave b by itself
b = 6 * 2
b = 12
Answer:
12
Step-by-step explanation:
8 + b/2 = 14
b/2 = 14 -8
= 6
b = 6 x 2
= 12
Therefore b is 12. Hope this helps you and pls mark me as brainliest <3

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

The value of x is -10. Steve made mistake in step 3 while transposing constant term and simplify.
The given equation is 8(2x + 7) = 6(x - 7) - 2.
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
Therefore, the value of x is -10. Steve made mistake in step 3 while transposing constant term and simplify.

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.
Answer:
First and fourth statements are correct
Step-by-step explanation:
The function is [tex]|x+3|<5[/tex] where the domain is [tex]-8<x<2[/tex]
[tex]|-2+3|=1<5[/tex]
The first statement is correct.
[tex]|1+3|=4<5[/tex]
Substituting a value into the inequality from the solution set, such as 1, will create a false statement. This is wrong as it creates a true statement.
[tex]|4+3|=7\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. This is wrong as a value which is not from the solution set will create a false statement.
[tex]|6+3|=9\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. This is correct.
[tex]|10+3|=13\nless 5[/tex]
Substituting any value into the inequality will create a true statement. This is wrong as the value of x must be in the solution set.
Answer:
1.) Substituting a value into the inequality from the solution set, such as –2, will create a true statement.
4.) Substituting a value into the inequality not from the solution set, such as 6, will create a false statement.

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,
An m×n matrix with m<n , then it has full rank when its m are linearly independent.
So, the given matrix 3 x 8 is the full rank matrix.
