<h3>Given</h3>
x² +y = 0
x³ -12x -y = 0
<h3>Find</h3>
the intersection point(s) (x, y)
<h3>Solution</h3>
Add the two equations together, then factor.
... (x² +y) + (x³ -12x -y) = 0 + 0
... x³ +x² -12x = 0
... x(x +4)(x -3) = 0
Then x = {0, -4, 3}.
The corresponding y-values are
... y = -x² = {0, -16, -9}
The points of intersection are (-4, -16), (0, 0), (3, -9)
Answer:
2 : 5 : 4.
Step-by-step explanation:
4 : 10 :8
Divide each number by 2:
= 2 : 5 : 4.
Answer:
x=0
Step-by-step explanation:
You must isolate the variable to solve for it, so subtracting 14 from the left is the first thing to do. This can be supported by using PEMDAS, whereas we are doing the inverse here to solve for something in the equation. This gives us 2x=0. Next, we have to divide by 2, which gives us x=0.
