The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable and if the highest power in the quation is 2 then it is a quadratic equation.

----> Quadratic Equation
Answer:
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
Answer:
Step-by-step explanation:
21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.
22. Again, the angles are supplementary which means that 61° + b = 180° → b = 119°.
23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.
24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°
Hope this helps!

139o
Step-by-step explanation:
Answer:
The slope intercept is y=mx+b
y=-1x (you go down one over one from your y-intercept)
y=-1x-1 (It would be minus one because that is where it crosses the y-axis)
