Try graphing y=x^3. It crosses the x-axis at (0,0), and this point represents the one and only real root.
Every form of a cubic function has a graph that crosses the x-axis in 1 or 3 places.
Thus, the correct answers to this particular problem are B and C.
Additionally, certain cubic function forms have graphs that cross the x-axis in one unique place, but which touch (but do not cross) the x-axis. Here you have one unique real root plus one repeated (duplicated) real root, for a total of 3 roots.
Using these facts, decide which of the four given answers are correct.
-10x-10 = -3x+4
+3x +3x
————————
-7x-10 = 4
+10 +10
————————
-7x = 14
then divide -7 on both side of the equal sign
you’ll get x=-2
then plug in -2 as x into one of the equations ( it doesn’t matter which one)
y= -10(-2)-10 = 20-10= 10
so y=10
Answer:
Step-by-step explanation:
If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.
The area of the circle is 95.03.
