A rational number is any number that can be expressed as the quotient or fraction
Answer:
Step-by-step explanation:
16.0 you’re welcome anything 5 or over gets rounded up 4 is less
Than 5 so it gets rounded down
Hmmm the y-intercept is at -2? what does that mean? well, is where the graph "intercepts" or touches the y-axis, and when that happens, x = 0, so the point is really ( 0 , -2 ).
and we know where the vertex is at. Let's assume a vertical parabola, in which case the squared variable is the "x".
X^2 - 12x = 61
Take half of the coefficient of the middle term (half of -12x), square this result, and then add, and then subtract, from -12x:
x^2 - 12x + (6)^2 - (6)^2 = 61
(x-6)^2 - 36 = 61, and so (x-6)^2 = 97
Note: These results are all equivalent; choose the one you think best.
