Answer:
x-intercept(s): (-2, 0), (6, 0)
y-intercept(s): (0, -6)
Step-by-step explanation:
An x-intercept represents the point(s) at which the parabola intersects the x axis. A parabola can have 0, 1, or 2 x-intercepts.
A y-intercept represents the point at which the parabola intersects the y axis. A parabola always has exactly 1 y-intercept.

Answer:
The equation of the graphed line is:
Step-by-step explanation:
From the graph, it is clear that the line is a horizontal line at y = 2.
We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.
In other words, the equation of the horizontal line would always get the form:
y = k
where k is the y-intercept of the line.
Determining the y-intercept of the line:
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept k = 2
Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation
y = 2
Therefore, the equation of the graphed line is:

Step-by-step explanation:
The 4 might be:
-1.9 - 3/2 , -1.8 and - 9/8.
In this question, it is given that
Walter wants computer software that cost $129. He has $57 saved.
he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.
![15x+57 \geq 129](https://tex.z-dn.net/?f=%2015x%2B57%20%5Cgeq%20%20129%20)
And we have to solve this inequality for x.
First we subtract 57 to both sides. And on doing so , we will get
![15x\geq 72](https://tex.z-dn.net/?f=%2015x%5Cgeq%20%2072%20)
Dividing both sides by 15.

Correct option is A.
Answer:
There were 6 guides on Sunday.
Step-by-step explanation:
Same ratio
On Saturday, 120 tourists and 18 guides.
On Sunday, 40 tourists and x guides.
Due to the same ratio:
![\frac{120}{40} = \frac{18}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B40%7D%20%3D%20%5Cfrac%7B18%7D%7Bx%7D)
![3 = \frac{18}{x}](https://tex.z-dn.net/?f=3%20%3D%20%5Cfrac%7B18%7D%7Bx%7D)
![3x = 18](https://tex.z-dn.net/?f=3x%20%3D%2018)
![x = \frac{18}{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B18%7D%7B3%7D)
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
