4 0

Answer:

(-8,0)

Step-by-step explanation:

Since the x and y of the mid point is less than the end point the line segment is going down. the difference between the end and mid point is 6 for x and 3 for y. -2-6 is -8 and 3-3 is obvi 0

Why is 4b-7-3b+9 equal to b+2
rodikova [14]
The first expression can be simplified by combining like terms.

First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"

Finally, we simply put these two final terms together, to form "b+2"

Hence, 4b-7-3b+9 is equal to be + 2.

Hope this helps!

What is the closed linear form for this sequence given a1 = 0.3 and an + 1 = an + 0.75?
german

Answer:

The closed linear form of the given sequence is a_{n}=0.75n-0.45

Step-by-step explanation:

Given that the first term a_{1}=0.3 and a_{n+1}=a_{n}+0.75

To find the closed linear form for the given sequence

The formula for arithmetic sequence is

a_{n}=a_{1}+(n - 1)d  (where d is the common difference)

The above equation is of the given form  a_{n+1}=a_{n}+0.75

Comparing this we get d=0.75

With a_{1}=0.3 and d=0.75

We can substitute these values in a_{n}=a_{1}+(n - 1)d

a_{n}=a_{1}+(n - 1)d

=0.3+(n-1)(0.75)

=0.3+0.75n-0.75

=-0.45+0.75n

Rewritting as below

=0.75n-0.45

Therefore a_{n}=0.75n-0.45

Therefore the closed linear form of the given sequence is a_{n}=0.75n-0.45
