Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
B I’m pretty sure I think or 826
Answer:
y=53x-7
Step-by-step explanation:
5x-3y=21

divide by 3
y=5/3x-7
