10 and 10 are equal so they stay the same.
Answer:
(-11+/-sqrt(73))/6 I might be wrong though
Step-by-step explanation:
The line will intersect the x-axis when y is 0, so you set the left side to 0(f(x) can be replaced by y), then you plug in the numbers into the quadratic equation, and finally solve the equation for the awnser.
Answer:
yes Our universe contains at least 70 septillion stars, 7 followed by 23 zeros. Astronomers estimate there exist roughly 10,000 stars for each grain of sand on Earth.
Step-by-step explanation:
700000000000000000000000

Move constant to the right-hand side and change its sign
2x^2 + 8 = -2 + 7
-2 + 7 = 5
Divide both sides of the equation by
x^2 + 4x = 5/2
Add (4/2^2) to both sides of the equation
x^2 + 4x + (4/2)^2 = 5/2 + (4/2)^2
factor the expression
(x + 4/2)^2 = 13/2
reduce the fraction by 2
(x + 2)^2 = 13/2
now solve equation for x
