solve -3x+y=7
please step by step :)

Answers

Answer 1

Answer:

x = 1; y = 10

Step-by-step explanation:

There's absolutely not enough information to find exact values for x and y with the information given, but using an example x value of 1, you can solve for y:

-3(1) + y = 7

-3 + y = 7

y = 10

4x + 3 = x + 2(x + 7)
step by step

Answers

Answer:

x=11

Step-by-step explanation:

4x + 3 = x+ 2x + 14

4x + 3 = 3 x + 14

4x - 3x = 14 -3

x= 14 - 3

x= 11

Answer:

x=11

Step-by-step explanation:

Distribute :

4x + 3 = x + 2( x+ 7)

4x + 3 = x + 2x + 14

Combine like terms :

4x + 3 = x + 2x + 14

4x + 3 = 3 x+ 14

Subtract 3 from both sides of the equation :

4x + 3 = 3x + 14

4x + 3-3 = 3x + 14 -3

Simplify :

what ever way you know how to subtract the numbers you should get this answer :

4x = 3x + 11

Subtract 3 from both sides of the equation :

4x = 3x + 11

4x - 3x = 3x + 11 - 3x

Simplify :

combine like terms

multiply by 1

combine like terms

x= 11

An arithmetic sequence is represented by the explicit formula A(n) = 2 +(n − 1)(− 5)
What is the recursive formula?

Answers

Answer:

a+(n-1)d please do you get it or

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5

Step-by-step explanation:

Given the explicit formula

A(n) = 2 - 5(n - 1)

Compare with the standard form

A(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = - 5

A recursive formula allows a term in the sequence to be found by adding d to the previous term.

Then recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5 , with a₁ = 2

If 5x - 2 = -12. then x =

Answers

Answer:

x = -2

Step-by-step explanation:

First let's solve the given equation.

5x - 2 = -12

Combine the constants by adding 2 to both sides.

5x = -10

Isolate x by dividing both sides by 5.

x = -2

This is your answer.

Check your answer by plugging x = -2 back into the equation.

5x - 2 = -12

5(-2) - 2 = -12

-10 - 2 = -12

-12 = -12

Your answer is correct.

Hope this helps!

if an is defined as a geometric sequence, is the sequence 1/an also a geometric sequence? explain your reasoning.​

Answers

Answer:

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

so, the ratio between terms is still constant.

Step-by-step explanation:

If an is defined as a geometric sequence, is the sequence 1/an also a

geometric sequence because the ratio between terms remain constant.

What is a geometric sequence and how to find its nth terms?

Suppose the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r

Then the sequence would look like

[tex]a, ar, ar^2, ar^3, \cdots[/tex]

 (till the terms to which it is defined)

Thus, the nth term of such sequence would be[tex]T_n = ar^{n-1}[/tex]

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

Therefore, the ratio between terms is still constant.

Y=2x that’s is the equation

I need help find this in slope intercept form

Answers

Answer:

y=2x+24 is you're answer

Answer:

I'm pretty sure it's y=2x+24

Step-by-step explanation:

The slope intercept formula is y=mx+b. So to get the equation into that form you would have to get y by itslef, which  means you would have to subtract 8x from both side. And then you can't have a number in front of the y so you have to divide by that for all of the terms.This then gives you your answer.
