Solve the system of equations using elimination. How many solutions does the system have?

Mathematics
1 answer:
Mariana [72]2 years ago
7 0

Answer:

  infinite solutions

Step-by-step explanation:

The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:

  (15x +12y) -3(5x +4y) = (18) -3(6)

  0 = 0 . . . . . simplify (true for all values of x or y)

The system of equations has an infinite number of solutions.

Hatshy [7]

The expected enrolment in 7 years is  1845.

<h3>What is the expected enrolment?
</h3>

The formula for calculating future value of the number of students is an exponential equation with this form:

FV = P (1 + r) ^n

  • FV = Future population
  • P = Present population
  • R = rate of growth of the population
  • N = number of years

1500 x (1.03)^7 = 1845

What’s the equation when the line is (6,5) and slope is 2/3
Vsevolod [243]

Answer:

y=2/3x+1

Step-by-step explanation:

using the slope intercept formula, y=mx+b, where m is the slope, and b is the y intercept. So we get the equation y=2/3x+b, because the slope is given, then you use the given point and substitute it into the equation, 5=2/3(6)+b which you can solve and you will get 5=4+b, b =1, then you add 1 to your original equation to get your answer, y=2/3x+1
