-3/2 × x - 9 = -27
+ 9
-3/2 × x = -18
× 2
-3 × 2x = -36
-6x = -36
÷ -6
x = 6
Hope this helps! Let me know if I've confused you or anything
Answer:
The correct answer is A) 3x(3x + 2)(3x - 2)
Step-by-step explanation:
In order to find this, first take out the greatest common factor.
27x^3 - 12x
3x(9x^2 - 4)
Now, what is left in parenthesis is the difference of perfect squares. This allows us to factor.
3x(3x + 2)(3x - 2)
The square root of 25 because you get a whole number (five)
Answer:
the first one
Step-by-step explanation:
2m+1
Get out your graphing paper. Since the slope formula is y=mx+b, we can say that +4 is b, which also stands for the y-intercept. Because +4 is the y intercept, place a point on (0,4). Then, using the slope (m or 3), we can figure out where the second point will go.
Slope is another word for rise over run. In this case it is 3/1 because that is what 3 is when converted to a fraction. So, from (0,4), we go up 3 and over to the right by 1 to plot the second point, (1,7). Connect the plotted points with the ruler.
Tldr; Plot a point at (0,4) because the y intercept is +4, plot a point at (1,7) because the slope is 3/1, and use a ruler to connect the two points in a line.
