Consider the function y=x^2-4x-21. See attached file for graph.

The y-intercept you can find substituting x=0 (or using graph):

y=0^2-4\cdot 0-21=-21.

Answer: y-intercept is (0,-21).

Factor the equation using difference of squares, which says that a^2-2ab+b^2=(a-b)^2.

a is 2 since the square root of 4 is 2 and b is 5 because the square root of 25 is 5.

Final answer: (2x-5y)^2

What is the value of x?<br><br><br><br> Enter your answer in the box.
Inessa05 [86]

Answer:

Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other

3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself

First add 10 to each side

3x+50+10=6x-10+10

3x+60=6x

Now we want to subtract 3x from each side

3x-3x+60=6x-3x

60=3x

Now divide both sides by 3

60/3=3x/3

20=x

x=20

Hope this helps ;)
