Which equation can be solved by using this system of equations? {y=3x^5-5x^3+2x^2-10x+4 {y=4x^4+6x^3-11 the answer choices are : a.) 3x^5-5x^3+2x^2-10x+4=0 b.) 3x^5-5x^3+2x^2-10x+4=4x^4+6x^3-11 c.)3x^5+4x^4+x^3+2x^2-10x-7=0 d.)4x^4+6x^3-11=0

For this case we have the following system of equations:
 {y = 3x ^ 5-5x ^ 3 + 2x ^ 2-10x + 4
 {y = 4x ^ 4 + 6x ^ 3-11
 From here, we must match both equations.
 By equating both equations, we obtain an equation that will depend on a single variable.
 Matching we have:
 3x ^ 5-5x ^ 3 + 2x ^ 2-10x + 4 = 4x ^ 4 + 6x ^ 3-11
 
 An equation that can be solved by using this system of equations is:
 B.) 3x ^ 5-5x ^ 3 + 2x ^ 2-10x + 4 = 4x ^ 4 + 6x ^ 3-11

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
