15x-3y=12
y=5x—4
I'm also not sure what your question is, but this is what I got by solving it like a regular equation.

15x-3(5x-4)=12
15x-15x+12=12
0=12-12
0=0

4x-y=-4
-8x+2y=2

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

-8x+2y=2
-8x+2(4+4x)=2
-8x+8+8x=2
0=-6

Use the given values of n to generate the 7th and 8th terms of the sequence.

lozanna [386]

Answer:

f(n) = 74 + 11(n - 1)

For the 7th term

n = 7

f(7) = 74 + 11(7 - 1)

= 74 + 11(6)

= 74 + 66

For the 8th term

n = 8

f(8) = 74 + 11( 8 - 1)

= 74 + 11(7)

= 74 + 77

4.9-16=. A:25 B:7 C:-25 D:-7

shtirl [24]

Answer and Step-by-step explanation:

It says your question is : $9-16=?$ And the answer for that would be $-10$ . But that's not there in the options I think your question was supposed to be meant like this : $16-9=?$ cause then it would be $7$ tho it's there in the options, the sign is wrong it's not $-7$ it's $+7$ or just $7$ .
