Intro:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The quickest way to do this is to look how much it goes down and then how much it goes left. This is called rise over run. So the line goes 2 down then left 3 to get from one perfect point to another.
So the answer is Choice D. It went down 2 so it's negative.
Answer:
2
Step-by-step explanation:
To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is

.
Let's perform step 1: reducing one side to variables only. By adding

to both sides of the equation, we get

.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of

is

, we need to divide both sides of the equation by 4:

. Rounded to the nearest tenth,

.
So the value of

that satisfies

is

.
6 x 10^-3 because the decimal point is 3 place value units away from the 6, and scientific notation is a x 10^n, where n can be a positive of a negative depending on the number
