A set of equations is given below:
Tasya [4]

Answer:

The number of solutions to the given set of equations is 0.

Step-by-step explanation:

Number of solutions of a system of equations:

System of equations: ax = b

If a = 0 and b = 0, infinite solutions.

If a = 0 and b != 0, zero solutions.

If a != 0 and b != 0, one solution.

We are given the following system of equations:

y = 7x + 12

y = 7x + 2

So

7x + 12 = 7x + 2

7x - 7x = 2 - 12

0x = -10

a = 0, b != 0, so zero solutions.

The number of solutions to the given set of equations is 0.

Which of the following are solutions to the quadratic equation? Check all that
Firlakuza [10]

Answer:

\boxed{\sf \ \ \ x=-9 \ \ or \ \ x=2 \ \ \ }

Step-by-step explanation:

hello,

2x^2+7x-14=x^2+4\\ 2x^2+7x-14-x^2-4=0\\ x^2+7x-18=0\\x^2-2x+9x-18=0\\ x(x-2)+9(x-2)=0\\ (x+9)(x-2)=0\\ x+9 = 0 \  \text{or} \ x-2=0\\ x = -9 \  \text{or} \ x=2

hope this helps
