Variables - a quantity that may change, depends on the context of the math problem.  Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc

PLEASE ANSWER I AM BEGGING YOU THIS IS RLLY CONFUSING AND I JUST WANT TO GET IT OVER WITH

6.

the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).

[just put a dot on the number four that's right under the letter y]

the slope of the line is positive, so it goes up from left to right.

Start at the y-intercept. Move up 2 and then move right 1.

You are now at the point (1,6).

[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]

7. y= -1/2-3

8. y=3x+4

-2(3x+2) is greater than or equal to -6x-4
olchik [2.2K]
The inequality would look like this:

-2 (3x + 2)\geq-6x-4

To begin to find the solutions, distribute the -2 throughout the set of parenthesis on the left side of the inequality by multiplying the -2 by each term in the set of parenthesis

-2 x 3x = -6x
-2 x 2 = -4

-6x -4 \geq-6x-4

Begin to isolate x by performing the opposite operation of adding -6x on both sides of the inequality

0x -4 \geq-4

Next perform the opposite operation by adding 4 on both sides of the inequality

0x \geq 0

Now, I'm not exactly understanding how that can possibly work. So, I guess I didn't really help you. But add a comment so that we can talk about the problem :)
