Answer:
x={-2,2}
Step-by-step explanation:
Graph them when intersecting.
Algebraically:
x^2 + 1 = -x^2 + 9
Add x^2 on both sides and subtract 1 on both sides.
2x^2 = 8
Divide 2 on both sides
x^2 = 4
Square root on both sides
|x| = 2
Remove abs value by putting + or - on the other side
x = {-2,2}

which is the question? (4/3)^2 is 16/9
The height of water increases by 2 inches per minute option first "The height of the water increases 2 inches per minute" is correct.
<h3>What is the slope?</h3>
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
We have given a table:
Time height
2 8
4 12
6 16
8 20
10 24
The slope of the line = (12-8)/(4-2) = 4/2 = 2
The value of the slope is positive we can say, the height of water increases as time passes.
Thus, the height of water increases by 2 inches per minute option first "The height of the water increases 2 inches per minute" is correct.

A pie chart organizes information depending on what your asking.
For instance,
there are 100 people living in an area.
The question is, what percentage of those people own a cat, dog, bird, fish, and other.
After gathering the results, it seems that,
30% have dogs
25% have cats
15% have birds
10% have fishes
20% have other pets
These results are what were given. And if u put this in a pie chart, you can see that most of those 100 people own dogs while least amount of people own fish. Also, if u add up all the percentages, it makes 100% which is anyways mandatory when making a pie chart, so always count them.
I hope this helps!!
please make my answer brainliest!!
Thank you so much!!
