When solving the radical equation 2+2x+11−−−−−−√=x, the values x=−1 and x=7 are obtained. Determine if either of these values is a solution of the radical equation. Select the correct two answers. Since substituting x=−1 into the original equation resulted in a true statement, x=−1 is a solution to this equation. Since substituting x=7 into the original equation resulted in a true statement, x=7 is a solution to this equation.

Since substituting x=7 into the original equation resulted in a false statement, x=7 is a not solution to this equation.

Since substituting x=−1 into the original equation resulted in a false statement, x=−1 is not a solution to this equation.

The length of triangle base is 26. a line, which is parallel to the base divides the triangle into two equal area parts. find the length of the segment between triangle legs.

When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
