Type quadratic equation in standard form x^2-11=4x

15x-21=5x^2

-7x^2=10-13x
​

Need this asap if anyone can i would be very grateful. if you could show workings that would really

Use the four functions below for this question. compare and contrast these four functions using complete sentences focus on the slope and y- intercept first, and then on any additional properties of each function

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
