Answer:
1-12x=-20-9x
-12x=-21-9x
-3x=-21
divide both sides by -3
x=-7

Answer: 2.2464 × 10^8
Step-by-step explanation:
Percentage of obese Americans in 2011 - 2012 = 35%
Percentage of Americans who are adult = 72%
United States population estimate = 312 million
Adult = age 20 and above
Number of adult Americans (age 20 and above) :
72% of the total united states estimated population
72% of 312,000,000
72/100 × 312,000,000
0.72 × 312,000,000
= 224,640,000
Hence, estimated Adult American population (age 20 and above) = 224,640,000
2.2464 × 10^8
Let's give it a try. Let the integers be x and y, understanding that both are -.
x - y = 8
x(y) = 308 Solve the first equation for x: x = 8+y. Subst. this result into the second equation:
(8+y)(y) = 308, or y^2 + 8y - 308 = 0
Quadratic equation with a=1, b=8 and c= -308.
-8 plus or minus sqrt(64-4(1)(-308) )
Then y = ----------------------------------------------------

Can you finish the arithmetic here? Find the 2 values of y.
Answer:
Step-by-step explanation:
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve
Answer:
point v at (3,-6)
point x at (1,-4)
other point that I can't see the letter lol is at (5,-3)
