Answer:

<em><u>2/10 and 3/10</u></em>

Step-by-step explanation:

Hello!

The best way of finding common denominators is using their factors!

(of denominators)

10 : 1, 2, 5, 10

2 : 1, 2

We also can see that 10 is divisible by 2.

For that reason, 1/2 is equivalent to 2 * 10 ÷ 2.

That's 10.

So <em>5/10 and 3/10</em> have a common denominator 10.

Hope this helps!

Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sid
puteri [66]

Answer:

See below

Step-by-step explanation:

1..........................

  • 18 >−7

Add –5; 2.7; 7 to both sides

  • 18 -5 > -7 - 5 ⇒ 13 > -12
  • 18 + 2.7 > - 7 + 2.7 ⇒ 20.7 > - 43
  • 18 + 7 > -7 + 7 ⇒ 25 > 0

2..........................

  • 5 > -3

Subtract 2; 12; -5 from both sides

  • 5 - 2 > -3 -2 ⇒ 3 > - 5
  • 5 - 12 > -3 - 12 ⇒ -7 > -15
  • 5 -(-5) > -3 - (-5) ⇒ 10 > 2

3..........................

  • - 9 < -6

Multiply both sides by 3; −3; −1

<em>When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses</em>

  • -9 *3 < -6*3 ⇒ -27 < - 18
  • -9*(-3) > -6*(-3) ⇒ 27 > 18
  • -9*(-1) > -6*(-1) ⇒ 9 > 6

Answer:

Axis is a vertical line at x = 2

Vertex is (2, -1)

y-intercept is (0, 3)

Solutions are x = 1 and x = 3

Step-by-step explanation:

To draw the graph of the quadratic equation you must find at least 5 points lie on the graph by choose values of x and find their values of y

Let us do that

Use x = -1, 0, 1, 2, 3, 4, 5

∵ y = x² - 4x + 3

∵ x = -1

∴ y = (-1)² - 4(-1) + 3 = 1 + 4 + 3 = 8

→ Plot point (-1, 8)

∵ x = 0

∴ y = (0)² - 4(0) + 3 = 0 + 0 + 3 = 3

→ Plot point (0, 3)

∵ x = 1

∴ y = (1)² - 4(1) + 3 = 1 - 4 + 3 = 0

→ Plot point (1, 0)

∵ x = 2

∴ y = (2)² - 4(2) + 3 = 4 - 8 + 3 = -1

→ Plot point (2, -1)

∵ x = 3

∴ y = (3)² - 4(3) + 3 = 9 - 12 + 3 = 0

→ Plot point (3, 0)

∵ x = 4

∴ y = (4)² - 4(4) + 3 = 16 - 16 + 3 = 3

→ Plot point (4, 3)

∵ x = 5

∴ y = (5)² - 4(5) + 3 = 25 - 20 + 3 = 8

→ Plot point (5, 8)

→ Join all the points to form the parabola

From the graph

∵ The axis of symmetry is the vertical line passes through the vertex point

∵ x-coordinate of the vertex point is 2

∴ Axis is a vertical line at x = 2

∵ The coordinates of the vertex point of the parabola are (2, -1)

∴ Vertex is (2, -1)

∵ The parabola intersects the y-axis at point (0, 3)

∴ y-intercept is (0, 3)

∵ x² - 4x + 3 = 0

∵ The solutions of the equation are the values of x at y = 0

→ That means the intersection points of the parabola and the x-axis

∵ The parabola intersects the x-axis at points (1, 0) and (3, 0)

∴ Solutions are x = 1 and x = 3
