A) The inverse of the statement is the opposite. The statement stated that if two lines do not intersect, they are parallel. So, the opposite would be if two lines intercept, they are parallel. This inverse statement is false because, that is not true. Parallel lines mean they never intercept, not if they intercept its parallel.

b) Converse means to engage or explain, I think…so, the converse of the statement would be that yes, it is true that when two lines do not intercept then they are parallel. Because parallel lines never cross or meet, meaning they will NEVER ever have a crossing point.

c) the contrapositive of the statement would be: if two lines do not cross then they are parallel. If they do intercept, then they are not parallel. As simple as that. I think contrapositive means that…I looked what contrapositive means…so I think I’m right.

I hope this helps!! Or some at least. :)

Good luck!

How much would you make for one month (4 weeks) if you worked a 40 hour week?
Anon25 [30]

Answer:

Unclear

Step-by-step explanation:

I believe we need more information to solve the problem!

We currently have:

a  = b

b = total amount for 40 hours

As you can see, we cannot solve this. For a we would need something like how much you make per week, etc!

What is 2x^2+9x-18 in vertex form?
atroni [7]

Complete the square:

2<em>x</em>² + 9<em>x</em> - 18

2(<em>x</em>² + 9/2 <em>x</em>) - 18

2(<em>x</em>² + 9/2 <em>x</em> + 81/16 - 81/16) - 18

2(<em>x</em>² + 2 (9/4) <em>x</em> + (9/4)²) - 81/8 - 18

2(<em>x</em> + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

<em>ax</em>² + <em>bx</em> + <em>c</em>

into its vertex form

<em>a</em> (<em>x</em> - <em>h</em>)² + <em>k</em>

where (<em>h</em>, <em>k</em>) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

<em>a</em> (<em>x</em>² - 2<em>xh</em> + <em>h</em>²) + <em>k</em>

<em>ax</em>² - 2<em>ahx</em> + <em>ah</em>² + <em>k</em>

For the two forms to be equivalent, we must have

-2<em>ah</em> = <em>b</em>

<em>ah</em>² + <em>k</em> = <em>c</em>

which means

<em>h</em> = -<em>b</em>/(2<em>a</em>)

<em>k</em> = <em>c</em> - <em>ah</em>² = <em>c</em> - <em>b</em>²/(4<em>a</em>)

In this case, <em>a</em> = 2, <em>b</em> = 9, and <em>c</em> = -18, so

<em>h</em> = -9/(2 • 2) = -9/4

<em>k</em> = 18 - 9²/(4 • 2) = -225/8

Solve the equation 4(x – 2) = 3x + 1.
Zina [86]

Answer:

x=9

Step-by-step explanation:

4(x – 2) = 3x + 1

Distribute 4x-8 = 3x+1

Subtract 3x from each side

4x -8-3x = 3x-3x + 1

x-8 =1

Add 8 to each side

x-8+8 = 1+8

x=9
