Note that the 2nd equation can be re-written as y=8x-10.
According to the second equation, y=x^2+12x+30.
Equate these two equations to eliminate y:
8x-10 = x^2+12x+30
Group all terms together on the right side. To do this, add -8x+10 to both sides. Then 0 = x^2 +4x +40. You must now solve this quadratic equation for x, if possible. I found that this equation has NO REAL SOLUTIONS, so we must conclude that the given system of equations has NO REAL SOLUTIONS.
If you have a graphing calculator, please graph 8x-10 and x^2+12x+30 on the same screen. You will see two separate graphs that do NOT intersect. This is another way in which to see / conclude that there is NO REAL SOLUTION to this system of equations.
Answer: A. -4
Step-by-step explanation:
6/((-4)^2-9)-(1/-4-3)= 6/7+1/7=1
Answer:y=1/2x+3
No Parenthesis or anything.
If angles are vertical it means opposite angles are the same size. Therefore the measures of the other three angles are 72 degrees, 108 degrees, and 108 degrees. I hope this helps!
