The equation of the line is
a. y=2x+3
b. y=-2x+3
c. y=3x-2
d. y=-2x+1.5
Side note: please show your work
Answers
Answer:
b. y=-2x+3
Step-by-step explanation:
find slope by getting any 2 points form the graph
(0,3) (1,1)
m = (y2-y1) / (x2-x1)
m = (1-3) / (1-0) = -2 it means by moving one unit right you need to move 2 unit down
note that it does not matter which points you chose to be second or first
then use slope point equation again it does not matter which point from the slope you use
y - y1 = m ( x - x1 )
y - 3 = -2 ( x - 0)
y = -2x +3
a) 2x+3
Step-by-step explanation:
The line passes throught the point (1;1) and (0;3)
gradient(m) =change in y ÷ change in x
=y1-y2 ÷x1-x2
=1-3 ÷ 1-0
=-2
therefore m is -2.
y-y1=m(x-x1)
y-1=-2(x-1)
y=2x+2+1
y=2x+3

Royce is folding a piece of paper to make an origami figure. Each time he folds the paper, the thickness of the paper is doubled. The paper starts out flat, with a thickness of 2 millimeters.
A. Write a list of six ordered pairs showing the output as the thickness of the paper when the input is the number of times it is folded. Explain how you came up with your ordered pairs.
B. Is this relation a function? Explain why or why not using the ordered pairs you came up with in Part A.
(Answer to get 50 pts and brainly)
Answers
Answer:
A.
(0, 2) (1,4) (2,8) (3,16) (4,32) (5,64)We start with (0,2) because before it's folded it has a thickness of 2mm. each consecutive fold doubles the y value.
B.
Yes it is a function because no x value is repeated
The list of six ordered pairs are {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}, and it is a function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Royce is folding a piece of paper to make an origami figure. Each time he folds the paper, the thickness of the paper is doubled.
Let y be the total thickness and x be the number of folds:
[tex]\rm y = 2^{x+1}[/tex]
Plug x = 0, 1, 2, 3, 4, 5,
Wea get list of six ordered pairs:
= {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}
This is an exponential function that passed the vertical test, it is a function.
Thus, the list of six ordered pairs are {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}, and it is a function.

Lauren has a points card for a movie theater.
She receives 60 rewards points just for signing up.
She earns 5.5 points for each visit to the movie theater.
She needs 104 points for a free movie ticket.
Write and solve an equation which can be used to determine xx, the number of visits Lauren must make to earn a free movie ticket.
Answers
Multiply points per visit x number of visits, using x for the number of visits:
5.5x
Add that to the points she already has:
5.5x + 60
This needs to equal a total of 104 points:
5.5x + 60 = 104
Now solve for x
5.5x + 60 = 104
Subtract 60 from both sides
5.5x = 44
Divide both sides by 5.5
X = 8
She needs 8 more visits

Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360
