Answer:
C and D
Step-by-step explanation:
The quadratic formula is
x= (-b±√b²-4ac)/2a
The formula uses the numerical coefficients in the quadratic equation.
The general quadratic equation is ax²+bx+c where a, b and c are the numerical coefficients
So, lets try and see;
A.

But due to the fact that in this equation you have x⁴, the equation is not a quadratic equation thus can not be solved using this formula
B

C

D.

From the checking above, the equations will be C and D
Answer:
The line of symmetry is x = 3
Step-by-step explanation:
To find the line of symmetry in this case, use the base formula for vertex form.
y = a(x - h) + k
In this formula, h is the line of symmetry. In this case, h is 3.
Step-by-step explanation:
To find the answer we first have to find the value of each percent, to do this we divide 100 by 350, that gets us approximately 0.286. We know that he won 154 of them we then multiply 154 by 0.286 to get the percentage of games he won and we get 44.044.
Answer:
4.53*10^7 because you have to move the decimal place then multiply by ten to the power of the amount you moved the decimal.
