Answer:
The number is 3.
Step-by-step explanation:
5x - 4 = 11
5x = 15
x = 3
Answer:
6c^2(-40 + 5c^3 + 3c^2)
Step-by-step explanation:
These three terms have the common factor c^2. Thus:
-240c^2+ 30c^5+ 18c^4 = c^2(-240+ 30c^3+ 18c^2).
Recognizing that 6 is common to all three terms inside the parentheses, we get:
6c^2(-40 + 5c^3 + 3c^2) This is as far as factoring of this expression can be taken.
5 1/4
(or 5.25)
typing this but bc it says your answer must be more than 20 characters lol
In this problem, they want you to take the triangle and flip it over the line. It's going to create a mirror image on the other side.
That line is y = x, which is just a basic plain diagonal line that goes bottom left to top right.
To start, I would ALWAYS write down the coordinates of the original triangle.
D (-1, 3)
F (-3, 1)
E (-1, 1)
Now, <em>here's the trick</em>
Anytime it asks you to flip over Y = X, <em>remember</em> that you just flip X and Y!!!
(X, Y) --> (Y, X)
Your new coordinate points are going to be:
D (3, -1)
F (1, -3)
E (1, -1)
Now, just plot those points, connect the dots, and you have your new, mirrored triangle!
