This exercise is asking you to find the value of b or solve for b, to do so you have to isolate or leave b alone by doing different mathematical operations according to the given equation.

The given equation is 12b+b-4b+3=12, which is a three step equation meaning that in order to solve for b you have to perform three different mathematical operations, in this case combining of like terms, subtraction, and division.

12b+b-4b+3=12              Combine like terms
            9b+3=12              Subtract 3 in both sides
                9b=9                Divide by 9 in both sides to isolate b
                  b=1

The value of ''b'' by which this equation is true is 1.

STEPS:

1. Add and subtract the same variables
2. Subtract 3 from 12
3. Divide whatever you got from 12-3 by your answer from step 1 (12-3 / b)
4. b = ?

Hope this helps! Please ask questions if you have any.

In the graph shown, suppose that f(x) = ax, g(x) = bx, and h(x) = cx. Choose the true statement.
faltersainse [42]
Where a, b, and c are real numbers and a ≠ 0 . The quadratic term is ax 2 , the linear term is bx, and the constant term is c. Quadratic functions have degree two. The graph of a quadratic function is called a parabola. If a < 0, then the parabola opens downward, like function g. If a > 0, then the parabola opens upward like function f. If the parabola opens upward, then the vertex is the point whose yvalue is the minimum value of f. If the parabola opens downward, then the vertex is the point whose y-value is the maximum value of f. The vertical line that goes through the vertex is called the axis of symmetry of the parabola.

The sum of squares of two consecutive positive even integers is 52 more than their product. Find these numbers.
natulia [17]

Answer:

The first set of consecutive even integers equals (8 , 6)

The second set is ( - 8 and - 6) which also works.

Step-by-step explanation:

Equation

(x)^2 + (x + 2)^2 = (x)(x + 2) + 52            Remove the brackets on both sides

Solution

x^2 + x^2 + 4x + 4 = x^2 + 2x + 52        Collect the like terms on the left

2x^2+ 4x+ 4 = x^2 + 2x + 52                  Subtract right side from left

2x^2 - x^2 + 4x - 2x + 4 - 52  =  0          Collect the like terms

x^2 + 2x - 48 = 0                                     Factor

(x + 8)(x - 6) = 0

Answer

Try the one you know works.

x - 6 = 0

x = 6

Therefore the two integers are 6 and 8

6^2 + 8^2 = 100

6*8 + 52  = 100

So 6 and 8 is one set of  consecutive even numbers that works.    

========================

What about the other set.

x + 8 = 0

x = - 8

x and x + 2

- 8  and -8 + 2 = - 8, - 6

(- 8 )^2 + (- 6)^2 = 100

(-8)(-6) + 52 = 100

Both sets of consecutive numbers work.

The scheme where you can find the greatest common divisor of two integers by repetitive application of the division algorithm is
HACTEHA [7]

Answer:

False

Step-by-step explanation:

Euclidean Algorithm is the algorithm that allows us to find the greatest common divisor (gcd) of two integers by repetitive application of the division algorithm.

A division algorithm is an algorithm which, given two integers N and D, computes their quotient and/or remainder.

Quotient and/or Remainder = \frac{N}{D}
