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
y +3 = -2x² +5----> Quadratic Equation
----> Quadratic Equation
----> Non Quadratic Equation
----> Non Quadratic Equation
y = 5 x(x + 9) - 8----> Quadratic Equation
----> Quadratic Equation
Answer:
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
how would I show work for this
Answer:
39
Step-by-step explanation:
5x - 1 when x = 8
plug the variable in
5(8) - 1
40 -1
39
Answer:
39
Step-by-step explanation:
5(8) is 40, minus one is 39.
