Answer:

x = -4.48,  8.48 to the nearest hundredth.

Step-by-step explanation:

x^2 - 4x - 9 = 29

Completing the square:

(x - 2)^2 - 4 - 9 = 29

(x - 2)^2 = 29 + 13 = 42

x - 2 = +/-√42

x = 2 +/-√42

x = 8.48, -4.48 .

Help on Number 8? I know Y=5 and the slope is undefined and x=2 but I don’t know what to do now.
Stels [109]

To find the slope, use the equation of a line: y = mx + b

Plug in the values for x and y:

5 = 2x + b

We know that 2 can fit into 5 twice, which means 2*2 is 4.

We now have 5 = 4 + b.

If 5 is b more than 4, then this means that 4 is b less than 5. Subtract 4 from both sides, and you will have b = 1.

This means your equation is y = 2x + 1.

Which pair of undefined terms is used to define the term parallel lines?
Ivan

Answer:

The correct answer for this is : A. Point and Line

Step-by-step explanation:

The lines are said to be parallel to each other if they do not intersect each other at any point. So, for any number of lines to be parallel we must have lines and no intersection points between them then only we can say the given number of lines are parallel to each other

So, the terms which are used to explain the term parallel lines here are : line and the point.

And the both terms point and a line are undefined in the geometry.

Hence, the correct answer for this is : A. Point and Line
