The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).

Answer:
6 blue marbles
Step-by-step explanation:
20 marbles * .30 are blue = blue marbles
20 * .30 = 6 blue marbles
Answer:
parallel
Step-by-step explanation:
w= x + y/z
w-x = y/z
z= y/(w-x)
y = (w-x)z
Fractions are division problems, ex 1/2 is the same as one divided by 2, so if you multiply the denominator you solve for the numerator, and to solve for the denominator just substitute what's on the other side
