Answer:
4) is a function 5) is not a function
Step-by-step explanation:
4) This is a function because even tho some numbers in the domain have the same y value that doesnt mean the x values overlap. THink of it graphically or draw points do the points overlap? It shouldn't unlike question 5!
5) This is NOT a function. Why??? This is because now all numbers except 4 have more than one y value for one x value
for example: 1 has -1 and 3
That would overlap!!
Answer:
i love algebra anyways
the ans is in the picture with the steps
(hope it helps can p lz have brainlist it will make my day
Step-by-step explanation:
<u>Spring tides:</u>
New Moon and Full Moon
The sun, Earth, and Moon are all roughly in the same line.
The gravitational effects of the sun and moon work in the same direction,
bringing higher high tides and lower low tides.
<u>Neap tides:</u>
First Quarter and Third Quarter Moon
(a week after New Moon and a week after Full Moon)
The sun, Earth, and Moon form a right angle.
The gravitational effects of the sun and moon work across each other, bringing
high tides that aren't quite as high, and low tides that aren't quite as low.
There are a pair of gravitational forces trying to pull the Earth and Sun together,
and another pair of gravitational forces trying to pull the Earth and Moon together.
So the Earth's oceans are pulled toward both the Sun and the Moon.
