Jordan is solving this system of equations: y = 2x2 + 3 and y – x = 6. which statements are true about jordan’s system? check all that apply. the quadratic equation is in standard form. using substitution, the system of equations can be rewritten as 2x2 – x – 3 = 0. there are two real number solutions. there are no real number solutions. a solution of the system of equations is (–1, 1.5).

The quadratic equation is in standard form.

Using substitution, the system of equations can be rewritten as 2x2 – x – 3 = 0.  

There are two real number solutions.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
