Answer:

1) x+2x+x+3 = 23

4x+3=23

4x=20

x=5

2) a_ radius × radius × pi = the area

4×4×3= 48

b_ diameter × pi= the circumfrence

8×3 = 24

3) a) 34_10=24

24÷3=8

b) _24_(_48)= 24

4) a) 2x=9_5

2x=4 => x=2

b)X/3 =12

x= 36

5) x. _2.

y. 3_(_2)=5

x. 0

y. 3_0=3

Example 2

Arada [10]

Answer:

y=x-2

Step-by-step explanation:

If you have drawn the graph of $y = x^2 - 3x + 1$ .

To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0

Simply carry out the subtraction: $x^2 - 3x + 1 -(x^2 - 4x +3)$

$\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3 + 1\\=x-2$

The equation of the line which should be drawn is: y=x-2

What this means is simply:

$y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0$
