For the left graph (y=2x^2), B) the graph will become narrower.
For the 2nd one (inequality):
![3 - 2x \geqslant - 17 \\ 3 - 3 - 2x \geqslant - 17 - 3 \\ - 2x \geqslant - 20 \\ - 2x \div - 2 \geqslant - 20 \div - 2](https://tex.z-dn.net/?f=3%20-%202x%20%5Cgeqslant%20-%2017%20%5C%5C%203%20-%203%20-%202x%20%5Cgeqslant%20-%2017%20-%203%20%5C%5C%20-%202x%20%5Cgeqslant%20-%2020%20%5C%5C%20-%202x%20%5Cdiv%20-%202%20%5Cgeqslant%20-%2020%20%5Cdiv%20-%202%20)
![x \leqslant 10... \: note \: inequality \: flips \\ when \: you \: divide \: by \: a \: negative](https://tex.z-dn.net/?f=x%20%5Cleqslant%2010...%20%5C%3A%20note%20%5C%3A%20inequality%20%5C%3A%20flips%20%5C%5C%20when%20%5C%3A%20you%20%5C%3A%20divide%20%5C%3A%20by%20%5C%3A%20a%20%5C%3A%20negative)
Therefore it is D)
I think the last one is C) 3 real and 2 imaginary zeros. Because the three real ones are where it crosses the x-axis.
Hello,
Answer C
y=3x+1
y=-x+5
==>3x+1=-x+5
==>4x=4
==>x=1 and y=-x+5=-1+5=4
(1,4) is the solution.

Step-by-step explanation:
Answer:
One forth of 20 is 5, so there are 5 kindergarten and first grade classrooms.
5 x 2 is 10 so there are 10 second and third grade classrooms.
10 + 5 is 15.
20 - 15 is 5.
There are 5 forth and fifth grade classes.
Step-by-step explanation:
The function that represents how much more water can be added to the bucket before it overflows is given as follows:
c(x) = 6x³ + 3x² - 2x - 2.
<h3>How to define the function?</h3>
The function to calculate the space remaining in the pool is given by the subtraction of the capacity function by the function representing the current amount of water in the pool.
The functions in this problem are defined as follows:
- f(x) = 8x³ + 4x² - 6x + 5.
- g(x) = 2x³ + x² - 4x + 7.
Then the capacity function is obtained as follows:
c(x) = f(x) - g(x)
c(x) = 8x³ + 4x² - 6x + 5 - (2x³ + x² - 4x + 7)
Then the distributive property is applied to the negative sign as follows:
c(x) = 8x³ + 4x² - 6x + 5 - 2x³ - x² + 4x - 7.
Finally, the like terms are combined, that is, the terms that have the same variable and exponent, as follows:
c(x) = 6x³ + 3x² - 2x - 2.
