3x + y = -3
Substitute y = x + 5 in the ‘y’ spot in the 3x + 7 = -3 equation
3x + y = -3
3x + x + 5 = -3
combine liked terms
4x + 5 = -3
-5 on both sides
4x = -8
/4 on both sides
x = -2
Answer:
x = -2
Answer:
Reflex angle
Step-by-step explanation:
Properties of reflex angles:
1). Any angle measuring between 180° and 360°.
2). Other side of the reflex angle is either acute or obtuse angle.
By these properties,
Since, angle C measures more than 180° but less than 360° and opposite angle is an acute angle.
By these properties angle C and angle D are the reflex angles.
Answer:
Step-by-step explanation:
a trinomial that cannot be factored has no real roots.
here is one:
After graphing this trinomial has no intersections points with the x-axis wich means it has no roots
