Count how many numbers -3 is to the left of zero and then that is the absolute value.
The absolute value of -3 is 3
One solution. Check images below for work.
Comment below for more questions or if the image is too hard to see :)
Take all the variables and put them next to each other but still in order.
Keep their negatives and positives.
6x-2x-9x 5y+3y
Do the math with the variables that way, and you'll get an answer of
-5x 8y
Reform them into the simplified equation, so you'll end up with an equation of
-5x+8y
The x would be before the y since that's how it is in the alphabet. That would be a simplified form of the equation.
Answer:
<em>x = 3</em>
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
<u>2x = 6</u>
(1 - 1 will cancel itself out on the side with the variable.)
Step 2:
Divide both sides by 2
2x = 6
2x ÷ 2 = 6 ÷ 2
<u>x = 6 ÷ 2</u>
(2 divide by 2, will cancel itself out on the side with the variable.)
Step 3:
Solve for x
6 ÷ 2 = 3
x = 6 ÷ 2 = 3
<u>x = 3</u>
Answer:
b. -2
Step-by-step explanation:
Note the slope-intercept form: y = mx + b
Note that:
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
First, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides of the equation:
2x (-2x) + y = (-2x) + 12
y = -2x + 12
Remember, m is the variable for the term that stands for the slope (directly next to the x variable). In this case, your answer will be -2
b. -2 is your answer.
