What is the value of the x variable in the solution to the following system of equations? (1 point) 4x + 2y = 12 x − y = 3

Pls , the question is in the picture!

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a

Given the quadratic function f(x)=3x^2-24x+49 a. use “completing the squares” to convert the quadratic function into vertex form b. state the vertex c. find the x and y intercepts d. graph the function
