M=2 , (6,6) <br> Write the equation in the form Ax+By=C.
Karolina [17]
Since m= slope =2, slope is rise/run, or (y2-y1)/(x2-x1), we'll make the point (6,6) = (x1,y1)
In point-slope form, y-y1 = m (x-x1) -->
y-6 = 2 (x-6)
y-6 = 2x-12
+6 = +6
y = 2x-6
-2x = -2x
-2x+y = -6

What is 31 billion in scientific notation
Nuetrik [128]

we know that

1  billion=1,000,000,000

In scientific notation

1,000,000,000=1*10^{9}

To find the value of 31 billion

Multiply the value of one billion for 31

so

31*1*10^{9} =31*10^{9}\\ =3.1*10^{10}

therefore

the answer is

3.1*10^{10}

Help please! will give brainliest!!!
TEA [102]

Answer:

m<1 = 69°

Step-by-step explanation:

Angles 20x + 11 and 25x - 14 are vertical angles, so they are congruent.

25x - 14 = 20x + 11

5x = 25

x = 5

The actual measure of angle 20x + 11 is 20(5) + 11 = 111°.

Angle 20x + 11 and <1 are supplementary, so the sum of their measures is 180°.

m<1 + 111° = 180°

m<1 = 180° - 111°

m<1 = 69°
