Answer:

5x + y = 8

Step-by-step explanation:

Given the equations:

x+3y=10 ____ (1)

2x−y=−1 ____ (2)

Multiply (2) by 2

2(2x - y = - 1) = 4x - 2y = - 2

4x - 2y = - 2 - - - (3)

Add (1) and (3)

4x - 2y = - 2

x + 3y = 10

___________

5x + y = 8

_________

Here's this too!!!!!
Oksanka [162]

Answer:

6. (a-4)(a+9)

7. (3p+4)(p-2)

8. Will explain below.

9. (5b+4)(5b-4)

Step-by-step explanation:

HELLOOO IM BACK

6. -4*9 = -36 (the variable), 9-4 = 5 (a) , so a^2 +5a - 36 is fulfilled.

7. 4*-2 = -8, 4-2 = 2, so 3p^2 - 2p - 8 is fulfilled.

9. 25b^2 = (5b)^2

16 = 4^2

Using the difference of squares formula, a^2-b^2= (a+b)(a-b)

Find the 70th term of the arithmetic sequence 29, 17, 5
ANTONII [103]

Answer:

857

Step-by-step explanation:

70th term = a + d(n-1)

d= 29-17=12

a=29

n-1 = 69

70th term = 29 + 12×69

= 29 + 828

= 857
