Explanation:
Start at the point (0,1). This is the y intercept, which is where the graph crosses the y axis.
Then move down 1 and over to the right 4 spaces. We arrive at (4,0) which is the x intercept.
The process of "down 1, over to the right 4" can be thought of like this
rise/run = -1/4
rise = -1
run = 4
A rise of -1 indicates we go down 1 unit
The run of 4 means we move to the right 4 units
So that's why slope = rise/run = -1/4
-------------------------------------------------------
Here's another approach using the slope formula:
m = (y2-y1)/(x2-x1)
m = (0-1)/(4-0)
m = -1/4
I used the two points (0,1) and (4,0) as (x1,y1) and (x2,y2) respectively. This formula basically says "subtract the y coordinates, subtract the x coordinates in the same order, then divide the differences y over x".
-------------------------------------------------------
Side note: The line moving downhill, as we read from left to right, indicates a negative slope.

this is because the bottom line has to equal 180, the angles given, 50 and 60, add up to 110, meaning the missing angle is 70 hope this helps :)
Answer:
30
Step-by-step explanation:
Add all the measures 50+35+85+65+60= 210
subtract 180 from 210 and you get
210-180 = 30
we use 180 because Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.

The probability of getting 2 or more "Winner" caps on 4 bottles of water
is 0.2616.
What is a binomial distribution in probability?In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.
The binomial probability is, [tex]^nC_xP^xq^{n - x}[/tex].
Let, p be the probability of winning,
Given, 1 out of every 4 bottles has the word "Winner".
Therefore, p = 1/4 and we know q = 1 - p = 3/4.
So, The probability of getting 2 or more "Winner" caps on 4 bottles of water
is P(X ≥ 2) which is, P(X = 2) + P(X = 3) + P(X = 4).
P(X ≥ 2) = [tex]^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].
P(X ≥ 2) = 6(1/4)²×(3/4)² + 4(1/4)³×(3/4) + 1(1/4)⁴×1.
P(X ≥ 2) = 0.2109 + 0.0468 + 0.0039.
P(X ≥ 2) = 0.2616 or 26.16%.

How does x = 0.7x + 24 equal 80?
Answers
Answer:
x=0.7x+24
We move all terms to the left:
x-(0.7x+24)=0
We get rid of parentheses
x-0.7x-24=0
We add all the numbers together, and all the variables
0.3x-24=0
We move all terms containing x to the left, all other terms to the right
0.3x=24
x=24/0.3
x=80
And that's how you get 80

Choose the graph of y = -3x – 1
Answers
Answer:
The line on the graph below is my answer.
The graph of function y = -3x – 1 has been drawn below.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the line equation y = -3x – 1
At x = 0 ⇒
y = -3(0) - 1
y = -1
So,
A(0,-1) is the first point on the line.
At y = 0 ⇒
0 = -3x – 1
x = -1/3
So,
B(-1/3,0) is the second point on the line.
Hence "The graph of function y = -3x – 1 has been drawn below".

Step-by-step explanation:
(x)(x)=x2,(x)(5)=5x

Answer: X^2 + 8x -15
Step-by-step explanation:
Use the foil method.
First, outer, inner, last
Multiply the first numbers inside each parenthesis. X*X = x^2
Next multiply the outer number in each parenthesis. X*5 = 5x
Then multiply the inner numbers of the parenthesis. -3*x= 3x
Finally multiply the last numbers in the parenthesis. -3*5 = -15
Now add all of these together
X^2 + 5x + 3x + -15
Combine like terms
X^2 + 8x -15
