Answer:
infinite
Step-by-step explanation:
if you graph the equation it would overlap.
overlap = infinite
parallel = no solution
intersect = one solution
Answer:
O y = -3
Step-by-step explanation:
The line is horizontal.
x = -3 and x = 3 are vertical lines, so they are incorrect.
The line passes through (3, -3).
(x , y)
Put y as -3.
y = 3
(-3) = 3
Line y = 3 is incorrect.
(-3) = -3
Line y = -3 is correct.
Solution: Let x be the height of a student in Marta's class.
The mean height of 18 students in Marta's class is 60 inches
We know that:




Therefore, the total measure of all 18 student's heights is 1080 inches
Answer:
c = 17 Km
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
c² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )
c =
= 17 Km
For this case we have the following equation exponentially:

Where,
- <em>A: initial population </em>
- <em>b: growth rate </em>
- <em>t: time in years</em>
Then, replacing values for 32 years we have:

Answer:
the approximate population in 32 years is:
