How many solutions does the following system of equations have? 2y=5x+4 y=3x+2 a. infinite many b.2 c.1 d.0

ella [17]

2y=5x+4
y= 3x+2

2(3x+2) = 5x+4
6x +4 = 5x+4
6x-5x=4-4
x=0-----------------------> y=3x+2
y=3(0)+2 = 0+2
y=2
solution (0,2) one point c.

To find the solutions to an equation of the form ax2+bx+c , use the quadratic equation: x=−b±b2−4ac√2a . What are the two soluti

lidiya [134]

Answer:

1.686

Step-by-step explanation:

Given is an quadratic equation as

$2x^2-x-4=0$

Also we are given the formula for general equation

$ax^2+bx+c$ as

$\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Here in our equation we have

$a=2\\b=-1\\c=-4$

Hence solution would be

$\frac{1+\sqrt{1+32} }{4} ,\frac{1-\sqrt{1+32} }{4} \\\frac{1+\sqrt{33} }{4} ,\frac{1-\sqrt{33} }{4}$

Greater would be the one with positive square root

$\frac{1+\sqrt{33} }{4} \\=1.6861\\=1.686$
