Figure 1 was translated using the rule (x', y') ⇒ (x -9, y + 2) to produce figure 2.

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are t<em>ranslation, reflection, rotation and dilation.</em>

Translation is the movement of a point either up, down, left or right on the coordinate plane.

Figure 1 was translated 9 units left and 2 units up using the rule (x', y') ⇒ (x -9, y + 2) to produce figure 2.

When factorising a quadratic trinomial of the form ax^2 + bx + c, we need to find two numbers which ???? (see image for options)
kupik [55]

Answer: Choice E

multiply to give a*c and add to get b

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

This is known as the AC factoring method based on how you multiply the first and last coefficients (a and c) and use that product to figure out which factors add to the middle coefficient.

---------

An example:

6x^2 + 35x + 50

We have a = 6, b = 35, c = 50

Multiply a and c and we get: a*c = 6*50 = 300

We need to find factors of 300 that pair up and add to 35

Through trial and error you should find,

15 * 20 = 300

15 + 20 = 35

The two numbers are therefore 15 and 20.

So we break 35x into 15x+20x and use the factor by grouping method

6x^2 + 35x + 50

6x^2 + 15x + 20x + 50

(6x^2 + 15x) + (20x + 50)

3x(2x + 5) + 10(2x + 5)

(3x + 10)(2x + 5)

We see that 6x^2 + 35x + 50 factors to (3x + 10)(2x + 5)

Use the FOIL method or the box method or distribution to help see that (3x + 10)(2x + 5) expands back to 6x^2 + 35x + 50.

Step-by-step explanation:

the perimeter =

4+4+6+4.5+2+4+4+2 =

30.5 cm

the area of:

• the bigger rectangle = 6×4 = 24 cm²

• the smaller triangle = 4×2 = 8cm²

• the triangle = ½×2×4 = 4cm²

the total area = 24+8+4 = 36cm²

Find the value of x in the equation: x + 0.17x = 160
mart [117]

Answer:

x=136.75

Step-by-step explanation:

Let's solve your equation step-by-step.

x+0.17x=160

Step 1: Simplify both sides of the equation.

x+0.17x=160

(x+0.17x)=160(Combine Like Terms)

1.17x=160

1.17x=160

Step 2: Divide both sides by 1.17
