<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:
X = 5

Answer:
9.) -2/2 = -1
10.) -6/-11 or 6/11
11.) -3/-11 or 3/11
Step-by-step explanation:
this is easy XD
So, first step the midpoint formula: (x1 + x2 / 2, y1 + y2 /2 )
9.) c(-9,-1) and D(7,3) ----> you should know the x and y and plug in :D
10.) E(5,-5) and F(1,-6)
----> you should know the x and y and plug in :D
11.) G(-5,3) and H(2,-8)----> you should know the x and y and plug in :D
Answer:
The solutions are
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
square root both sides
