Answer:

The equation of the line that passes through (9,-2)&(4,2) is

y=-4/5x+26/5

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=2-(-2)/4-9

m=4/-5

m=-4/5

y-y=m(x-x¹)

y-2=-4/5(x-4)

y-2=-4/5x+16/5

+2 +2

y=-4/5x+26/5

Inequalities are used to show the relationship between unequal expressions

  • <em>The set notation of (5) and (6) are: </em>\{x : -6 > x \ge -2\}<em> and </em>\{x:-4 < x \ge 6\}<em>.</em>
  • <em>See attachmen</em>t for the graphs

The following should be notated when plotting the graph of an inequality

  • < and > are represented with open circles, while \leq and \geq are represented with closed circles
  • The arrows of and \le point to the left, while the arrows of > and \geq point to the right.

So, we have:

(a)\ -8 < x

Rewrite as:

x > -8

The graph of x > -8 will point to the right, and it will use an open circle

(b)\ -6 > x \ge -2

Split the inequality:

-6 > x and x \ge -2

<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>

<em />

Hence. -6 > x \ge -2 cannot be represented on a graph

(c)\ -4

Split the inequality:

-4 < x and x \ge 6

-4 < x means that -4 is less than x or x is greater than -4.

So, we have:

x > -4 and x \ge 6

If x > -4 and x \ge 6, then we make use of x > -4 because it contains more values of x.

The graph of x > -4 will point to the right, and it will use an open circle

AB = 9 cm
BC = 6cm

CD = 7 cm
AE = 6 cm

3BC = AB
3ED = AE

  AB = AE
  BC    ED
    ⁹/₃ = ⁶/ₓ
3 · 6 = 9 · x
   18 = 9x
    9      9
     2 = x

ED = 2 cm
