Pls help for 27b!!!!!!!
rodikova [14]

Step-by-step explanation:

\beta

is a root of the quadratic

4 {x}^{2}  - 10x + 5

This quadratic isn't factorable so use the quadratic formula

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

The plus and minus sign after b means we going to have two roots.

The roots are

\frac{5 +  \sqrt{5} }{4}

and

\frac{5 -  \sqrt{5} }{4}

We subsitue those values for Beta.

27a.

\frac{5}{2}

27b.

Here’s a graph of a linear function. Write the equation that describes that function
inessss [21]

Answer:

The equation of the line is y = 1/4x - 4

Step-by-step explanation:

In order to find this, start with two points that are on the line. We'll use (0, -4) and (4, -3). Now we can use the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - -3)/(0 - 4)

m = -1/-4

m = 1/4

Now that we have this, we can use that slope and a point in point-slope form. Then we solve for y to get the equation.

y - y1 = m(x - x1)

y - -4 = 1/4(x - 0)

y + 4 = 1/4x

y = 1/4x - 4
