Answer:

x^2+7x+2

Step-by-step explanation:

hi! you can only combine terms with the same power (exponent value).

if we stack this like a regular addition problem, it will be easier.

x^2 + 4x + 5

3x - 3

-----------------------

4x+3x is 7x, and 5+ (-3) is 2. we keep the x^2 the same.

therefore, the answer is x^2+7x+2

hope this helps!

Find the solution to the system of equations. Select all that apply

PolarNik [594]

Answer:

A. (1,0)

Step-by-step explanation:

When you're solving a system of equations algebraically, you're finding the point that exists on both functions. So, when you're finding the solution graphically, you just need to find the point where the two functions intersect. In this case, it's A. (1,0)
