Hi

Just told you :  first know by heart remarkable identities !  

Then apply :  

4x²-12x = -9

4x²-12x +9 =0

(2x-3)² = 0

(2x-3) (2x-3)  = 0

Now you have a double solution :

Are (2,9) and (-3,-6) both on the line y - 4x + 6? If not, find an equation for the line that does pass through both points.

Answers

Answer:

points doesn't lie in the given line.

Step-by-step explanation:

firmula for finding the equation of these points are

[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} [/tex]

x1=2 , x2=-3, y1= 9 ,y2=-6

subtitute all values in formula

[tex] \frac{y - 9}{ - 6 - 9} = \frac{x - 2}{ - 3 - 2} [/tex]

[tex]y - 3x - 3 = 0[/tex]

if we put (2,9) and (-3,-6) in new equation then they will satisfy equation.so this is the equation where points lie in the line

is 16 a natural, whole, integer, rational or irrational number?

Answers

Answer:

6 is a natural, whole and integer

Step-by-step explanation:

16 is a natural, whole and integer

it is not rational or irrational because

rational numbers are written in p/q as well as irrational

natural numbers start from 1 till infinite

whole numbers start from 0 to infinite

integers include all the positive and negative numbers

Answer:

rational

Step-by-step explanation:

Write an equation of the line that passes through the point (-6, -9) with slope-5.
A. y + 9 = 5(20+6)
B.y +6 = 5(x +9)
c.y+9= -5(x + 6)
D.y +6 = -5(x +9)

Answers

Answer:

[tex]y+9=-5(x+6)[/tex]

Step-by-step explanation:

We are being asked to write the equation in point-slope form:

[tex]y-y_1=m(x-x_1)[/tex] where m = slope and the first point = [tex](x_1,y_1)[/tex]

In this case, the slope is -5 and the point is [tex](-6,-9)[/tex] so the equation will be:

[tex]y+9=-5(x+6)[/tex]
