How can you solve a system composed of a linear equation in two variables and a quadratic equation in two variables? Will give BRAINLIEST :) Need a clear answer asap 50 points will be earned!

Very simple.. Whenever there are two variables in a equation there is always a simultaneous equation for that equation. By using two equations we can easily find the value of two variables.

For example x= 2+ y and y = x-2

HOW TO: GIVEN A SYSTEM OF TWO EQUATIONS IN TWO VARIABLES, SOLVE USING THE SUBSTITUTION METHOD.

1.) Solve one of the two equations for one of the variables in terms of the other.

2.) Substitute the expression for this variable into the second equation, then solve for the remaining variable.

3.) Substitute that solution into either of the original equations to find the value of the first variable. If possible, write the solution as an ordered pair.

4.) Check the solution in both equations.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
