Period would be the distance between 2 peaks

looking at the graph there is a peak on x= 1 and then a peak on x= 4
4-1 = 3 so the peak is 3

the amplitude is the midpoint between the highest point and lowest point
on the graph
the high point is y=1 and the low point is y = -2
1 + -3 = 3 spaces, midpoint = 3 / 2 = 1.5 so the amplitude = 1.5

the answer is the first one.

Answer:

$(-4,-5 )$

Step-by-step explanation:

You are looking for the point of intersection of these two functions.

Substitution:

This are now your formulas

$\left \{ {{x=-4y-24} \atop {5x+3y=-35}} \right.$

You are going to substitute x, so you can solve for y

$5(-4y-24)+3y=-35$
$-20y-120+3y=-35$
$-17y=85$
$y=-5$

Now you are going to substitute y to find x

$x=-4(-5)-24$
$x=20-24$
$x=-4$

Now lets check if it is correct

$-4+4(-5)=-24 :)$
$5(-4)+3(-5)=-35 :)$

So it is true, making (-4 , -5) your point of intersection.

hope it helps

True or False: Like the edges of a filled-in area, the endpoints of a polygon do not need to conform to snap points.

kirill [66]

Answer:

The answer is "False."

Explanation:

An area is considered the amount of space that an object occupies. A filled-area subjects the object to be made up of lines. These lines connect with each other to form an "edge."

The connection of the lines in order to define the object's shape or area are considered "snap points." Remember that "polygons" are made of line segments, where their endpoints meet with each other in order to define its closed shaped. <u>Thus, it needs to conform to "snap points."</u>

This explains the answer.
