Work out the area of this circle

Solve the following inequalities and show the solution on a number line. 3/4 (2x-7) ≤ 5

Find the solution(s) to x^2-14+49=0

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
