Answer:

The y-intercept of the line is 2

Step-by-step explanation:

You could try to find the slope of the line and then find the intercept with y axis by sloving b = y - ax

But here it seems easy enough once you see that the x values in the table increase by a factor of 8 and the y values in the table increase by a factor of 20.

(By the way, this is enough to give you the slope, because it is 8/20 ). But why bother?

Just extrapolate the table to the left, and you will find the y value where x = 0

x 0 8 16 24 32

y 2 22 44 64 84

So the y-intercept of the line is 2.

Extra:

The full equation of the line is:

y = 8/20x + 2

Trevor plans on buying a car. Four banks offer the annual interest rates shown.

mote1985 [20]

Solution

In order to find greatest to least number, we have to convert the given fractions into decimals.

3 $\frac{1}{10}$ % = 3 + 1/10 = 3 + 0.10 = 3.10%

3 $\frac{2}{5}$ % = 3 + 2/5 = 3 + 0.40 = 3.40%

3 $\frac{1}{4}$ %= 3 + 0.25 = 3.25%

3 $\frac{1}{3}$ % = 3 + 0.33 = 3.33%

Now we can easily, compare the numbers and write from greatest to least.

3.40%, 3.33%, 3.25%, 3.10%

Greatest to least = 3 2/5%, 3 1/3%3, 3 1/4%, 1/10%,

Thank you :)

Solve for the roots in simplest form using the quadratic formula: 4x2 + 4x = -5

weqwewe [10]

Answer:

Step-by-step explanation:

Move all terms to one side

4x^2 + 4x + 5 = 0

Plug into quadratic formula

x = (-4 + $\sqrt{16 - 4(4)(5)}$ ) / 2(4)

= (-4 + $\sqrt{-64}$ )/8

At this point, there are no real answers. The roots to this equation are complex.

x = (-4 + 8i)/8

= (-1 + 2i)/2
