Need the answer to​ this thank you!
Sholpan [36]

Answer:

n = 4

Step-by-step explanation:

Use the explicit formula of a arthmetic sequence: an = a1 + d(n - 1)

a1 = -70

d = -10

an = -100

Do all of the steps and plug all the numbers with the formula.

So -100 = -70 - 10(n - 1)

-100 = -70 - 10n + 10

-100 = -60 - 10n

-100 + 60 = -40

-40 = -10n

-40/-10n = -10n/10

n = 4

So the final answer is n = 4. Just follow all of the steps and you will understand how I got my answer. Hope it helped!

Please solve the following system of equations <br> x+3y=8 <br> 2x-y=2
Anuta_ua [19.1K]

Answer:

(2,2)

Step-by-step explanation:

Given equations are

x+3y=8       eq(1)

2x-y=2        eq(2)

we'll solve the system of equation by substitution.

Adding -3y to both sides of eq(1),we get

x+3y-3y=8-3y

x+0=8-3y

x=8-3y     eq(3)

Put above value of x in eq(2),we get

2(8-3y)-y=2

16-6y-y=2

16-7y=2

Adding -16 to both sides of above equation,we get

-16+16-7y=-16+2

0-7y=-14

-7y=-14

Dividing by -7 to both sides of above equation,we get

-7y/-7=-14/-7

y=2

Putting y=2 in eq(3),we get

x=8-3(2)

x=8-6

x=2

hence, the solution for this system of equations is (2,2).
