fingers
Step-by-step explanation:
Answer: April is correct.
Step-by-step explanation: According to the methods used in systems of equations, if we are to solve this system by setting up the equations
(3 = -2x + 1), we see that the solution is x = -1. If you substitute this x-value back into the original equation, y = -2x + 1, we get the answer y = 3 and thus, receiving the solution to the system (-1,3). Anthony is wrong because the graph includes an extra line at x = 3, throwing off his answers.
Answer: B) The result is a prime number
==================================================
Explanation:
Replace x with 5. Then use PEMDAS to simplify.
7x+6
7*5+6
35+6
41
The expression 7x+6 is equal to 41 when x = 5.
The value 41 is prime because its factors are only 1 and 41.
50 x .40 = 20
50 - 20 = 30
approx. $30
Answer:
If I get 2=3 in solving the system, it means the following:
- If the system of equations is 2 linear equations in 2 variables, the system has no solutions
- If the system of equations is 3 linear equations in 3 variables, the system has no solutions
Step-by-step explanation:
The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.
The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.
When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.
constant = constant
So,
If I get 2=3 in solving the system, it means the following:
- If the system of equations is 2 linear equations in 2 variables, the system has no solutions
- If the system of equations is 3 linear equations in 3 variables, the system has no solutions
