Perpendicular lines gradients times to get -1 so you just use a line with any y intercept but the gradient must times with the gradient you already have to get minus one.

Put each formula in y=mx+b form, then find the inverse of m.
Ex:
1. x+y=2
y=x-2
the inverse of 1 is -1 so the perpendicular line would be y=-x-2

Answer:

$\displaystyle y=14\cdot x$

Step-by-step explanation:

<u>Directly Proportion</u>

It's said that y varies directly proportional as x, if:

$y=k\cdot x$

Where k is a constant of proportionality.

We know that y=7 when x=1/2.

Using the above condition, we can find the value of k:

$\displaystyle 7=k\cdot \frac{1}{2}$

Solving for k:

k=14

Thus, the equation is:

$\boxed{\displaystyle y=14\cdot x}$

9/20 because if you count the red and blue out of the 20, theres 9. So you have a 9/20 chance it will hit red or blue.

Answer:

The answer is 2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

2/ 3(x)=4/9

Step 1: Multiply both sides by 3/2.

( 3/2)*(2/3*x)=(3/2)*(4/9)

so this means the answer is 2/3

Answers:

f) hard working. Think of "industry" or "industrial" to help remember.
b) state of disorder. Mayhem is effectively chaos.
e) expressions of sorrow. For example, you would give lamentations at a funeral.
i) gridlock or standstill. Example: "Congress is at an impasse on passing a new spending bill". You can think of it like saying "it's not possible to pass or get through".
a) A long angry rant or speech. I'm not sure what trick you can use to remember this, but the term "harangue" sounds negative which seems to be fitting with the angry rant/speech.
c) Overly concerned about small details. Usually you might hear it used in a way where someone mentions "not to be pedantic", they basically mean "not to nitpick at the fine details".
h) Terrible; extremely poor. Someone who is abominable has bad morals or values as a person. For instance, a murderer is someone who is abominable.
d) Characterized as having too high of an opinion of oneself. Someone with a big ego only thinks about themself and no one else. The tern narcissism also applies.
g) The effects of something. Specifically, repercussions are referred to as unintended consequences of an action.
j) The act of surrendering. I don't know of a useful trick to help remember this term.
