Answer:
Any line with the slope of 4/3 would be perpendicular.
Step-by-step explanation:
To find this, first solve the equation for y.
3x + 4y = 7
4y = -3x + 7
y = -3/4x + 7/4
Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/4 becomes -4/3) and then we change the sign (-4/3 becomes 4/3)
Answer:

Answer:
F (x) = -3x+5x^2+8 has complex roots.
Step-by-step explanation:
number of roots?
ok.
f(x) = 5xx - 3x + 8 = 5xx + 5x - 8x + 8 ( I was guessing what numbers would sum to -3)
nope.
ok try discriminant: (-3)^2 - 4*5 * 8 = 9 - 160 < 0
2 complex roots
