Answer:

a) The addition property of equality

b) The division property of equality

Step-by-step explanation:

Here, we want to know the correct step to use

From the given question, to proceed;

All we have to do is to move the value that has a negative value on the left hand side to the right hand side

what accompanies this is the addition of the both terms, on the right hand side

After this, we now proceed to divide the sum by the coefficient of x

Thus, the correct choices are;

a) The addition property of equality

b) The division property of equality

Answer:

25.67 ; 25.71 ; 25.79

Step-by-step explanation:

Give the measurement :

25.67 cm, 25.79 cm, and 25.71 cm.

Arrangement of numbers on a line plot is arranged in ascending order ( lowest to highest)

Hence,

25.67 < 25.71 < 25.79

Therefore they will follow the arrangement :

25.67 ; 25.71 ; 25.79

Answer:

If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.

We also know that Pythogoras' theorem only holds for right angled triangles.

The hypotenuse is 12 + 8 as 12 is the radius so is 20.

16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.

Step-by-step explanation:

The equation for the discounted cost :

c - 0.15c

Initial cost = c

Discount percent = 15% = 15/100 = 0.15

Discount on sale = 0.15 * c = 0.15c

Hence,

Discounted price = initial price - discount on sale

Discounted price = c - 0.15c

c - 0.15c = 0.85c

Answer:

Step-by-step explanation:

The only way in which you can truly simplify this is to factor the quantity within parentheses.  Use the quadratic formula for this purpose:

y^2 - 2y + 4 has coefficients {1, -2, 4}.  The discriminant is b^2 - 4ac, which here is (-2)^2 - 4(1)(4), or 4 - 16, or -12.  Since the discriminant is negative, we know that the roots of this quadratic are complex, different:

       -b ± i√(discriminant)

y = ---------------------------------

                    2a

                -(-2) ±i√12          2 ±i2√3)

Then y = ------------------- = ---------------- = 1 ±i√3

                        2                       2

and we end up with these three factors:  x, x - 1 +i√3, x - 1 -i√3

So the original expression becomes -3·y·(y-1i√3)(y - 1 -i√3)

Answer:

x = 3 and y = 8

Step-by-step explanation:

The Opposite sides of a parallelogram are equal and parallel. It means,

[tex]\dfrac{y}{2}=4\\\\y=8[/tex]

Also,

5x - 6 = 3x

Taking like terms together,

5x -3x = 6

2x = 6

x = 3

So, the values of x and y are 3 and 8 respectively.

Answer: x + 10

Step-by-step explanation:

The 10th term of the arithmetic sequence will be:

= a + 9d

where a = 3x + 4

d = x + 10 - (3x + 4)

= x + 10 - 3x - 4

= -2x + 6

Therefore, a + 9d = 3x + 4 + (-2x + 6)

= 3x + 4 - 2x + 6

= 3x - 2x + 4 + 6

= x + 10

Answer:

38m

Step-by-step explanation:

Area of rectangle = length x breadth

perimeter of a rectangle = 2 x( length + breadth)

The factors of 18 are 1,2, 3,6,9,18

The possible areas and perimeters of the flowerbed based on the factors are

1 x 18 = 18cm^2  Perimeter = 2(1+18) = 38

2 x 9 = 18cm^2  perimeter = 2 (2+9) = 22

3 x 6 = 18cm^2 perimeter = 2 (6 +3) = 18

the greatest is 38m

Answer:

c(n) = 2.25n + 4

g(n) = 2n + 6

Solve:

[tex]g(n) = c(n)[/tex]

so:

[tex]2n + 6 = 2.25n + 4\\2 = 0.25n\\n = 8[/tex]

plug this in:

[tex]g(n) = 2n + 6\\g(n) = 2 * 8 + 6\\g(n) = 16 + 6 = 22[/tex]

The method of completing the squares method will be used for the next step. The next step would be ( x+ (b/2a)  )^2 = -c/a + b^2/(4a^2)

Suppose that two terms are 'a' and 'b'.

Then, their sum's square is expanded as:

[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]

For this case, we're given the quadratic equation with its 4 steps of solution as:

[tex]ax^2 + bx + c = 0\\\\\dfrac{ax^2}{a} + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} = -\dfrac{c}{a}\\\\x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = -\dfrac{c}{a} + \dfrac{b^2}{4a^2}[/tex]

We've to proceed to the next step.

In the left hand side, we can use the formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex], where [tex]\rm a \: is \: x^2, and \: b \: is \: \dfrac{b}{2a}[/tex]

Thus, we have:

[tex]x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = x^2 + 2 \times x \times \dfrac{b}{2a} + \left(\dfrac{b}{2a} \right)^2 = \left( x + \dfrac{b}{2a} \right)^2[/tex]

We expressed the left sided expression in this form so that the variable 'x' (which is assuminly the only variable in the equation, whose value is to be known) gets packed into single container and not spread throughout with different powers.

Now, we can use square root and then subtraction and division of some terms which will make 'x' stay on one side of the equation, and rest of the constants on other side, as the value of 'x' for which the considered equation [tex]ax^2 + bx + c = 0[/tex] is correct.

The next step of the solution, therefore, is:

[tex]\left( x + \dfrac{b}{2a} \right)^2 = \dfrac{-c}{a} + \dfrac{b^2}{4a^2}[/tex]
