Write an equation for the line graphed?
Answer:
The equation of the line is:
y = 2/3x - 3
The graph is also attached below.
Step-by-step explanation:
From the given diagram, let us take two points
(0, -3)
(4.5, 0)
Determining the slope between (0, -3) and (4.5, 0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-3\right),\:\left(x_2,\:y_2\right)=\left(4.5,\:0\right)[/tex]
[tex]m=\frac{0-\left(-3\right)}{4.5-0}[/tex]
[tex]m\:=\frac{3}{4.5}[/tex]
[tex]m=\frac{3}{\frac{45}{10}}[/tex]
[tex]m=\frac{3\cdot \:10}{45}[/tex]
[tex]m=\frac{2}{3}[/tex]
Therefore, the slope of the line is:
m = 2/3
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 given point
(0, -3)It is clear that at x = 0, the value of y = -3
Thus, the y-intercept b = -3
now substituting b = -3 and m = 2/3 in the slope-intercept form of the line equation
y = mx+b
y = 2/3x + (-3)
y = 2/3x - 3
Therefore, the equation of the line is:
y = 2/3x - 3
The graph is also attached below.

describes the end behavior of the graph.
Answer:
+ ∞
Step-by-step explanation:
If you look at the graph you can see that the arrow is pointing upward, indicating that the graph continues in that direction forever. Also, the question is asking, as you move the right (or as x increases) what happens to y. y is increasing infinitely in end behavior.

John rolls a number cube labeled 1-6 and flips a coin. What is the
probability of rolling a 5 and landing on Heads?
The probability of rolling a 5 for John is 16.666 percent. Because there is 5 other numbers , it is possible but you would have to add all numbers together and then divide it with 100 cause that’s will be how much the percent would be. So you would divide 100 with 6 and then the answer is 16.666 which is also the percentage for John to roll the dice and get a 5.

Answer:
x=y and thats it
Step-by-step explanation:
Answer:
x=y
Step-by-step explanation:
Because, if the beams are parallel, <x & <y will be alternate angles which are equal in measure. So, In reverse way, if x=y, then the beams will be parallel.
8. Determine whether the triangles are similar. If so, write a similarity
statement and the postulate or theorem that justifies your answer.
Answer:
Option (4)
Step-by-step explanation:
If ΔLMN is similar to ΔQRS,
Their corresponding sides will be proportional.
[tex]\frac{LM}{QR}= \frac{MN}{RS}= \frac{LN}{QS}[/tex]
[tex]\frac{5}{6}= \frac{3}{4}= \frac{6}{7}[/tex]
But it's not true.
Therefore, the given triangles ΔLMN and ΔQRS are not similar.
Option (4) will be the answer.

a) Write the sequence of natural numbers which are multiplied by 3 ?
b) Write the sequence of natural numbers which are multiplied by 3 and added to 1 ?
c) Check whether the sequence obtained above is an arithmetic sequence or not?
Answer:
a) 3, 6, 9, 12, 15,...,[tex]3\cdot n[/tex], b) 4, 7, 10, 13, 16,...,[tex]3\cdot n +1[/tex], c) Both sequences are arithmetic.
Step-by-step explanation:
a) The sequence of natural numbers which are multiplied by 3 are represented by the function [tex]f(n) = 3\cdot n[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...
b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function [tex]f(n) = 3\cdot n + 1[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...
c) Both sequences since differences between consecutive elements is constant. Let prove this statement:
(i) [tex]f(n) = 3\cdot n[/tex]
[tex]\Delta f = f(n+1) -f(n)[/tex]
[tex]\Delta f = 3\cdot (n+1) -3\cdot n[/tex]
[tex]\Delta f = 3[/tex]
(ii) [tex]f(n) = 3\cdot n +1[/tex]
[tex]\Delta f = f(n+1)-f(n)[/tex]
[tex]\Delta f = [3\cdot (n+1)+1]-(3\cdot n+1)[/tex]
[tex]\Delta f = 3[/tex]
Both sequences are arithmetic.

The length of a rectangle is 4 cm longer than the width, The perimeter is 80cm. Find the length and the width.
Answer:
the length is 22 and the width is 18
Step-by-step explanation:
The perimeter is 2(l) + w(2)
w is the width and l is the length
if you plug in 22 and 18 you get
2(22)+(2)18
then you do multiplication to get
44+36
then you add and you get 80

Answer:
3x^2-4x+8 (R -1)
Step-by-step explanation:
We can use synthetic division:
-2 | 3 2 0 15
____-6 8 -16
3 -4 8 | -1
So basically, you solve x+2=0 (which is x=-2) and then you put it on the left side. Then make a line and put the coefficients of the polynomial you want to divide. Then with the first coefficient it gets dropped. You would then multiply this by -2 (so 3*-2=-6) and then combine it with 2 in the second column (2+-6=-4). Then we do the same thing with the third column (-4*-2=8) and combine (0+8=8). Same with the fourth column (8*-2=-16) but when we combine this time the answer will be our remainder (15+-16=-1).
So how you would read your final answer is 3x^2-4x+8 (R -1) which the numbers you get are the coefficients.

the change in altitude of a bird after 2 1/2 seconds was -41 1/4 feet. what was the average change in altitude of the bird in feet per second
PLEASE HELP
Answer:
-16¹/₂ feet per second
Step-by-step explanation:
average change in altitude in feet per second = change in altitude in feet/change in time in seconds
= -41¹/₄ ft ÷ 2¹/₂ s
= -165/4 ft ÷ 5/2 s
= -165/4 × 2/5 ft/s
= -33/2 feet per second
= -16¹/₂ feet per second
