Complete the sequence of numbers in the set. Explain the pattern.The completed sequence of numbers is​ 8.5, 7.15,​ 5.8,
Mademuasel [1]

Answer:

8.5,7.15,5.8,4.45,3.1,...

Step-by-step explanation:

The first step to solve this question is to analyze the given sequence.

We can notice that the difference between 8.5 and 7.15 is

8.5-7.15=1.35

And again the difference between the second and the third term is :

7.15-5.8=1.35

One way to describe all the numbers in the sequence is by using a formula.

We can write :

Given the sequence a_{0},a_{1},a_{2},a_{3},...

a_{n}=8.5-(1.35)n with n ∈ IN_{0}

For example :

a_{2}=8.5-(1.35).2=5.8   which verifies our original sequence.

We can obtain any term we want of the sequence.

Some of the terms that complete the sequence are :

8.5,7.15,5.8,4.45,3.1,...

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form
raketka [301]

Answer:

y-3= 2(x-1)

Step-by-step explanation:

1. The equation of a line in point slope form is y-y1= m(x-x1)

2. m=slope and (x1,y1) is the point the line passes through

3. The point the line passes through is (1,3)

4, The slope is 2

5. Therefore the answer is y-3=2(x-1)

Solve the following system of equations please ASAP
swat32

Given:

The system of equation:

x+y = -4 -------- (1)

y = x^{2} -6x --------- (2)

To find the values of x and y.

We will use substitution method.

From (1) we get,

y = -4-x

We will put the value of y in (1) and we get,

-x-4 = x^{2} -6x

or, x^{2} -5x+4= 0

Now we will apply middle term factor method.

  x^{2} -(4+1)x+4 = 0

     x^{2} -4x-x +4 = 0

x(x-4)-1(x-4) = 0

       (x-4)(x-1)= 0

so, x = 4 and 1

Now,

Substitute x = 4 in (1) we get,

y = -4-4 = -8

And putting x = 1 in (1) we get,

y = -4-1 = -5

Hence, the solution of the given system of equation is (4,-8) and (1,-5)

Thus, Option A is the correct answer.

Which of the following fractions would use bar<br> notation?<br> 5/6<br> 1/10<br> 1/20<br> 1/12
OLga [1]

Answer:

I am pretty sure 5/6 and 1/12

Step-by-step explanation:

Because 5/6 = 0.83333 (repeating) -- which means you use bar notation over the three

The same for 1/12 = 0.083333 (repeating) -- which means you use bar notation over the three
