Answer:

(3.5, 1.5) and (1, -1).

Step-by-step explanation:

As both expressions in x are equal to y we can write:

2x^2 - 8x + 5 = x - 2

2x^2 - 9x + 7 = 0

(2x - 7)(x - 1) = 0

2x - 7 = 0 or x - 1 = 0

x = 3.5, 1,

When x = 1, y = 1 - 2 = -1.

When x = 3.5, y = 3.5 - 1 = 1.5.

Help. I need both. Please

Anything to the power of 0 is 1

So for the top, 2^0 = 1
For the bottom, 10^0 = 1

It is not 0, because anything that ends with 0/0 is undetermined, and will not result in an answer

hope this helps

What is the distance of the line? Remember the distance formula is (23 - 23) + (42 -

vivado [14]

Answer:

The distance of the line is 10.82

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The graph clearly shows the points (-5,4) (4,-2), thus the distance is:

$d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}$

$d=\sqrt{81+36}=\sqrt{117}=10.82$

The distance of the line is 10.82
