PLEASE HELP!!!!

alina1380 [7]

Answer:

B, D, E

Step-by-step explanation:

-8x - 6y = 10

x + 7y = 9

You can multiply any of these equations by a constant without changing the solution.

B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.

D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.

E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.

A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.

C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.

F. x - 14y = -18 is wrong. The coefficient of x should be -2.

F(x)= x^2– 3x + 9<br> g(x) = 3x^3+ 2x^2– 4x – 9<br> Find (f - g)(x).

denis-greek [22]

Answer:

$\large \boxed{\sf \ \ -3x^3-x^2+x+18 \ \ }$

Step-by-step explanation:

Hello, please consider the following.

$(f-g)(x)=f(x)-g(x)=x^2-3x+9-(3x^3+2x^2-4x-9)\\\\=x^2-3x+9-3x^3-2x^2+4x+9\\\\=\boxed{-3x^3-x^2+x+18}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
