Calculate the rise and run to find the slope of each line! Please help me!!!
Answers
The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run" (change in y divided by change in x).
slope of the line = -5/4.
How do you find a slope of a line?Choose two points on the line and calculate their coordinates. Determine the difference in y-coordinates between these two points (rise). Determine the difference in x-coordinates between these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run" (change in y divided by change in x).The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It is usually simple to graph a line using y=mx+b.The line pass through the points (-3, 2) and (1, -3)
The formula for finding slope from two points (x₁, y₁) and (x₂, y₂) on a line is m = (y₂ - y₁) / (x₂ - x₁). Here, m = slope of the line
m = -3-2/1 +3 = -5/ 4
slope of the line = -5/4.

The sum of the first 26 terms for an arithmetic sequence is 1417.
The sum of the first 8 terms for the same arithmetic sequence is 76.
Find the value of the first term.
Answers
The value of the first term is -8.
Here it is given that the series is in an arithmetic sequence.
The formula for the sum of a series in an arithmetic sequence.
[tex]S_{n}[/tex] = n/2( 2a + (n-1)d)
n = number of term
d = common difference
a = first term of a sequence
[tex]S_{n}[/tex]= sum of n number of terms
It is given that sum of 26 number of a term is 1417, and the sum of first 8 number of a term is 76.
So from that, we have two equations by putting the term in the equation
1417 = 26/2( 2a + (26-1)d)
1417 = 13(2a + 25d)
109 = 2a + 25d .........(1)
76 = 8/2( 2a + (8-1)d)
19 = 2a + 7d ..........(2)
Now subtract equations (1) and (2) we get
90 = 18d
d = 5
Now put the value of d in equation (2), we get
19 = 2a + 7× 5
19 - 35 = 2a
2a = -16
a = -8
Therefore the first term of the sequence is -8.

There are 2 pictures.
1. (x,y)=(-1,5),(0,2),(1,-1),(2,-4). Option -3 is correct.
2. The slope of the line is 4/3. Option-1 is correct.
Given that,
There are 2 pictures.
In the first picture we have to find which table satisfy the equation.
In the second picture we have to find slope of the given graph.
First,
The given equation is y=-3x+2
In every option the x values are same that is -1,0,1,2.
Substitute x value as -1,0,1,2
Taking x as-1
y=-3(-1)+2
y=3+2
y=5
Taking x as 0
y=-3(0)+2
y=2
Taking x as 1
y=-3(1)+2
y=-3+2
y=-1
Taking x as 2
y=-3(2)+2
y=-6+2
y=-4
Therefore, we got (x,y)=(-1,5),(0,2),(1,-1),(2,-4). Option -3 is correct.
Now, We see the second picture.
Given line point are (2,2) and (-1,-2)
Slope of the line formula is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Slope =(-2-2)/(-1-2)
Slope=-4/-3
Slope=4/3
Therefore, the slope of the line is 4/3. Option-1 is correct.

a soft drink machine outputs a mean of 27 ounces per cup. the machine's output is normally distributed with a standard deviation of 2 ounces. what is the probability of putting less than 31 ounces in a cup? round your answer to four decimal places
Answers
The probability of putting less than 31 ounces in a cup is 0.9773.
The standard score is the number of standard deviations that a raw score deviates from or exceeds the mean of the thing being measured or observed. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.
A soft drink machine's output is normally distributed.
The mean is μ = 27 ounces per cup.
The standard deviation, σ = 2 ounces.
The z score when x is a random variable that represents the output of the machine will be given as:
Z = ( X - μ)/σ
Z = ( 31 - 27)/2
Z = 4/2
Z = 2
Then the probability of putting less than 31 ounces in a cup using the p-value from the Z table will be:
P( X < 31 ) = 0.97725
P( X < 31 ) ≈ 0.9773

For a project in her Geometry class, Chloe uses a mirror on the ground to measure the height of her school’s flagpole. She walks a distance of 8.85 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.1 meters to the other side of the mirror, until she can see the top of the flagpole clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.15 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
Answers
The height of the flagpole will be 9.25 m to the nearest hundredth of a meter.
What is geometry?It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
Given that, after moving a mirror with an X in the middle to a level position on the ground 8.85 metres away from the flagpole.
The top of the flagpole is then plainly indicated in the X as she moves 1.1 metres to the opposite side of the mirror. Her companion calculates that there are 1.15 metres between her eyes and the ground.
From the similarity of two triangle,
1.15 / h = 1.1 / 8.85
1.1 h = 1.15 × 8.85
1.1 h = 10.1775
h = 9.25 m
Thus, the height of the flagpole will be 9.25 m to the nearest hundredth of a meter.

Answers
The coordinate of the intercepts of the graph are (0, -1) and (1/3, 0).
What is termed as the coordinate intercepts?An intercept is a y-axis point whereby the slope of a line passes. It is the y-coordinate of a point on the y-axis in which a straight line or a curve intersects. This is represented by the equation for a straight line, y = mx+c, where m is the slope and c is really the y-intercept.There are two types of intercepts: x-intercept and y-intercept. The x-intercept is the point in which the line crosses the x-axis, and the y-intercept is the point in which the line crosses the y-axis.The equation of the line is given as;
y = 3x - 1.
For x-intercept put y = 0;
0 = 3x - 1.
x = 1/3
x-intercept = (1/3, 0)
Now, for y-intercept, put x = 0.
y = 3x0 - 1
y = -1
y-intercept = (0 , -1)
Thus, the coordinates of the intercepts are (0, -1) and (1/3, 0).
