6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8

3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5

 y = 6x - 31
 y = 6(5) - 31
 y = 30 - 31
y = -1

answer
x = 5 and y = -1

h = -16t^2 + 541? its been forever since i had to do this and frankly I'm completely lost. please if you answer this can you tea

A = -16  b = 0  c = 541
Use the quadratic formula which is
x = [-b +- sq root (b^2 -4*a*c)] / 2*a
x = [-0 +-sq root (0 -4*-16*541)] / 2 * -16
x = + - sq root (0 -4*-16*541) / -32
x = + - sq root (34,624) / -32
x = + - 186.075 / -32

x1 = 186.075 / -32 = <span> <span> <span> -5.81484375 </span> </span> </span>
x2 = -186.075 / -32 = <span> <span> <span> 5.81484375 </span> </span> </span>
