Answer my math question I asked so many times I lost most of points by

a=1

b=2

c=-8

y-intercept: (0, -8)

Line of symmetry calculation: x = -2/(2*1)

Line of symmetry: -1

Opens up because a > 0

Minimum

Vertex: (-1, -9)

Domain: -∞ < x < ∞ (no domain constraints)

Range: [-9, ∞]

Step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
