Answer:

x=-8, x=1/4, x=5.

Step-by-step explanation:

The degree is 3, so there must be 3 roots.

factor: x^2(4x-1)+3x(4x-1)-40(4x-1)=0

=(4x-1)(x^2+8x-5x-40)=0

=(4x-1)(x+8)(x-5)=0

x=1/4, -8, 5

y=√(2x+5)

using a graph tool
see the attached figure

the solution is
x=-0.175
y=2.156

therefore

Which equation represents the line shown in the graph below?

likoan [24]

The answer is y=2x+5

To get it use point slope by taking two points and solving .

Slope formula

M= y2-y1/x2-x1

With two points

(0,5)(-5,-5)

M= -5-5/-5-0

M= -10/-5

M=2

2 is slope

Now get one of the points

(0,5) And slope to create equation y=mx+b . Now find b

5=2(0)+b

5=b

So now you can put it all together

Y= 2x+5
