Asap ! will mark ! if the sum of x and y is 90 and y is 6 more than four times x, which of the following systems of equations could be used to solve for x and y? a. x+y =90 6x-y= -4 b. x+y=90 4x-y= -6 c. x+y=90 x-4y=6 d. x+y=90 4x-y=6

On a cm grid, point p has coordinates (3,-1) and point q has coordinates (-5,6) calculate the shortest distance between p and q give your answer to 1 decimal place

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
