Are y=2x+6 and 6t=2x+9 perpendicular
babymother [125]

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 2 2 . The equation of a perpendicular line to y=2x+9 y = 2 x + 9 must have a slope that is the negative reciprocal of the original slope.

Missing: 6t= ‎| Must include: 6t=

Find 5 rational numbers between 1/3 and 2/7 and arrange in ascending order.
likoan [24]

2/7=0.2857142857

1/3=0.3333

A rational number is that number that can be expressed as a ratio of 2 integers.

The 5 numbers could be:

0.29=29/100

0.3=3/10

0.31=31/100

0.32=32/100=8/25

0.33=33/100

These numbers are not unique.

Give a recursive definition of each of these sets of ordered pairs of positive integers. [Hint: Plot the points in the set in th
konstantin123 [22]

Answer:

(2,1), (1,2) is your base step

if (a,b)   is in the set (a+1,b+1) will be in  the set

if  (a,b) is in the set (a+2,b) will be in the set

if (a,b) is in the set (a,b+2) will be in the set.

Step-by-step explanation:

Think about how to solve this problem in general. How can you assure that the sum a+b is odd ?

Think about this, what happens when you sum two even numbers ? The result is even or odd ?

2+6 = 8 (even  )

10+12 = 22 (even)

And what happens when you sum two odd numbers ? The result will be even or odd ?  Look

3+7 = 10 (even)

5+11 = 16 (even)

Therefore to assure that a+b is odd, one of them has to be odd and one of them has to be even, that is why

(2,1), (1,2) is your base step

if (a,b)   is in the set (a+1,b+1) will be in  the set

if  (a,b) is in the set (a+2,b) will be in the set

if (a,b) is in the set (a,b+2) will be in the set.
