Answer:

  y +2 = -3(x -2)

Step-by-step explanation:

The point-slope form of the equation of a line is useful for this:

  y -k = m(x -h)   . . .    for a line of slope m through point (h, k)

__

  y +2 = -3(x -2) . . . . fill in the given values. Note that -(-2) = +2

In the sequence 400, 200, 150, 75, 25...... what number comes next
Scorpion4ik [409]

Answer:

The next term in the sequence = -175

Step-by-step explanation:

Here, the given sequence is : 400, 200, 150, 75, 25...

Now here, in the given sequence,

First Term - Second Term = 400 - 200 = 200

Second Term -   Third Term   =  200  - 150  = 50

Third term  - Fourth Term  = 150 - 75   = 75

Fourth term - Fifth term = 75 - 25 =  50

So, following this pattern,

Fifth Term - Sixth term = 200

Or, 25 - Sixth Term = 200

or, Sixth term  =  25 - 200  = - 175

Hence, the next term in the sequence = -175

ABC IS a right angled triangle at B and D is a point on BC. If AD=18cm , BD=9cm and CD = 4 cm, find AC
leva [86]
AB =  \sqrt{ AD^{2} - BD^{2} } =  \sqrt{243} = 9 \sqrt{3} 

AC = \sqrt{ AB^{2} + BC^{2} } =  \sqrt{412} = 2 \sqrt{103}
