Parallel,

That chart probably relates to a transversal line you have above it with the numbers on the 3 lines. When it says "Parallel lines" it means what lines are parallel between the two given numbers. Example: Question a) is saying
Angle 10 is congruent to Angle 15, therefore what two lines that they're on or next to are parallel. In many cases, it would be the ones that they're on.

Converse, 

The "Converse" is also known as "Alternate Interior Angles". Meaning angles that are on the same side of the transversal and are inside of it. Example: On the bottom of your page (near question 2) the angles 4 and 5 are transversals and so is 3 and 6. So just write down the converse of each given value or angle.

Hope this helped!

Im doing decimals greatest to least and i need help with number 12 and 13
erma4kov [3.2K]

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D

The equation x^2+ (k - 3)x + (3 - 2k) = 0, where k is a constant, has two distinct real roots.
Lisa [10]

Step-by-step explanation:

For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,

b^2 - 4ac must be positive.

b^2 - 4ac > 0

(k - 3)^2 - 4(3 - 2k) > 0

k^2 - 6k + 9 - 12 + 8k > 0

k^2 + 2k - 3 > 0

masya89 [10]

2(x-4)=5(4-2x)+4x

2x-8=20-10x+4x

2x+10x-4x=20+8

8x=28\\x=\frac{28}{8}

x=\frac{28/4}{8/4}=\frac{7}{2}  \\x=\frac{7}{2}
