Reformatting the input :

Changes made to your input should not affect the solution:

(1): "1.25" was replaced by "(125/100)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*x*(x-3)-((125/100)*x^2)=0

Rewriting the whole as an Equivalent Fraction

4.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 4 as the denominator :

2x • (x - 3) 2x • (x - 3) • 4

2x • (x - 3) = ———————————— = ————————————————

1 4

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2x • (x-3) • 4 - (5x2) 3x2 - 24x

When a fraction equals zero :

6.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

3x•(x-8)

———————— • 4 = 0 • 4

4

Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

3x • (x-8) = 0

Theory - Roots of a product :

6.2 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

6.3 Solve : 3x = 0

Divide both sides of the equation by 3:

x = 0

Solving a Single Variable Equation:

6.4 Solve : x-8 = 0

Add 8 to both sides of the equation :

x = 8

Answer:

Step-by-step explanation:

a. HM = 14

HN = 21

HK = 10.5

Based on intersecting chords theorem,

HK*HJ = HM*HN

10.5*HJ = 14*21 (Substitution)

HJ = 294/10.5

HJ = 28

b. VC = 7.2

VG = 12

Based on tangent-secant theorem, thus:

VD*VC = VG²

VD*7.2 = 12²

VD = 144/7.2

VD = 20

Therefore,

CD = VD - VC

CD = 20 - 7.2

CD = 12.8

Answer: 9

Step-by-step explanation:

The area of the obtuse triangle given is,

⇒ Area of triangle = 9 square units

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The obtuse triangle given below.

Here, Base = 9

And, Height = 2

Now, WE know that;

⇒ Area of triangle = 1/2 × Height × Base

Put all the values we get;

⇒ Area of triangle = 1/2 × Height × Base

⇒ Area of triangle = 1/2 × 2 × 9

⇒ Area of triangle = 9 square units

Thus, The area of the obtuse triangle given is,

⇒ Area of triangle = 9 square units

Answer: independent variable = x, Dependent variable = y, Domain = {1,2,3}, Range = {10.5, 12, 13.5}

Step-by-step explanation:

Given :  function y = 1.5x + 9 represents the cost y (in dollars) of a large pizza with a toppings, where x is equal to  1, 2, or 3.

here , independent variable = x  (Number of toppings on with cost is dependent)

Dependent variable = y

Domain = Set values of x = {1,2,3}

At x =  1 , y = 1.5+9 = 10.5

At x= 2 , y=  1.5(2) + 9 = 12

At x= 3,  y = 1.5(3) + 9 = 13.5

Range = set of values of y = {10.5, 12, 13.5}

Answer:

£38.48

Step-by-step explanation:

First, we have to find what 4% of 37 is, so our equation is:

37 x 0.04 = 1.48

Then we have to add that 4% to the original cost:

1.48 + 37 = 38.48

So the total price of the theatre ticket is  £38.48

Q'(0, -1)

R'(2, 5)

S'(-1, 0)

T'(-2, 9)

Step-by-step explanation:

Rule defined by [tex]T_{(-1,2)}.R_{\text{x-axis}}[/tex]

Step 1). Reflection of the figure about x-axis

(x, y) → (x, -y)

Step 2). Followed by the translation of 1 unit to the left and 2 units up  

(x, y) → (x - 1, y + 2)

Transformation of QRST by this rule,

Step 1.

Q(1, 3) → Q"(1, -3)

R(3, -3) → R"(3, 3)

S(0, 2) → S"(0, -2)

T(-2, 1) → T"(-2, -1)

Step 2.

Q"(1, -3) → Q'(0, -1)

R"(3, 3) → R'(2, 5)

S"(0, -2) → S'(-1, 0)

T"(-1, -1) → T'(-2, 9)

Answer:

9 weeks.

Step-by-step explanation:

The equation 5w+16=61 models how many weeks, w  it takes a puppy to reach a weight of 61  ounces after being born.

5w+16=61

Subtract 16 from both sides of the above equation.

5w+16-16=61-16

5w = 45

w = 9

Hence, the puppy will take 9 weeks to reach 61 ounces.
