The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 =
{-5, 3}
Answer:
A) Steve = Ryan +18
B) Steve + Ryan = 144
A) Steve -Ryan = 18 then adding B
B) Steve + Ryan = 162
2 Steve = 162
Steve weighs 81 pounds
Ryan weighs (81 -18) pounds 63 pounds
Step-by-step explanation:
Answer:
for number 1, you plug -3 in for x in the equation. and for number 2, you plug in 2 for y in the equation. you do this to find the missing values of the variables.
1. y= -10
2. x= -1
Step-by-step explanation:
i hope this helps :)

Answer:
Greatest: Denmark
Least: U.S.
Step-by-step explanation:
The population density is calculated by dividing the population by the area.
U.S.
Population density = 272,648,000/9,364,520 = 29.1
Denmark
Population density = 5,248,000/42,077 = 124.7
Ghana
Population density = 18,339,000/237,533 = 77.2
Greatest: Denmark
Least: U.S.
