The equation in slope-intercept firm for this line is y = -4/3x - 13
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the linear equation?The given parameters are
Slope, m = -4/3
Point (x1, y1) = (-6, -5)
The linear equation is calculated as
y = m(x - x1) + y1
So, we have
y = -4/3(x + 6) - 5
Open the bracket
y = -4/3x - 8 - 5
Evaluate the difference
y = -4/3x - 13
Hence, the equation in slope-intercept firm for this line is y = -4/3x - 13

Measures of Variation, Standard Deviation, Population Variance, Population. Can someone help?
To solve this problem one must be aware of the concepts of standard deviation and variance of raw data.
There is a direct formulae to calculate the variance of the data,
Variance = [tex]σ^{2} =\frac{Sigma(xi-m)^{2}}{n}[/tex]
Now here we need to verify ∑x and ∑[tex]x^{2}[/tex].
∑x = 21+19+15+32+27
= 114
and ∑[tex]x^{2}[/tex] = [tex]21^{2} +19^{2} +15^{2} +32^{2} +27^{2}[/tex]
= 441+361+225+1024+729
= 2780
So, the given relation is true.
Now the variance of the given data by putting the values in the formulae is equal to 45.2.
And Standard deviation=[tex]\sqrt{Variance}[/tex]
= [tex]\sqrt{45.2}[/tex]
= 6.72
And for population α²=36.16 and deviation=6.01.

Divide 38 in two parts such that one part is 18 more than the other
Answer:
10 and 28
Step-by-step explanation:
let x be one number then the other is x + 18 ( 18 more than the other ), then
x + x + 18 = 38
2x + 18 = 38 ( subtract 18 from both sides )
2x = 20 ( divide both sides by 2 )
x = 10
and x + 18 = 10 + 18 = 28
the 2 numbers which divide 38 into the 2 parts are 10 and 18

Answer:

Step-by-step explanation:
shirts = 10, price per shirt = $9
shirts = 25, price per shirt = $8.40
Linear equation be:
y = mx + b
x = 10 , 25
y = 9 , 8.40
9 = 10m + b
8.4 = 25m + b
9 = 10 m + b b = 9 - 10m
8.4 = 25m + b 8.4 = 25m + 9 - 10m
8.4 - 9 = 15m m = -0.6/15 = -0.04
m = - 0.04
b = 9 - 10m = 9 - 10(-0.04) = 9+0.4 = 9.4
b = 9.4
The linear equation =
y = mx + b
y = -0.04x + 9.4

if n represents a number, then write an expression for the product of the number with a number that is seven more than it.
Answer: N * (n+7) = n^2 + 7n
Step-by-step explanation:
This equation would be the number, n, times n+7 because n+7 is 7 more than n. To do this, you have an equation like this:
N * (N+7). You would then do distributive property, and n*n would be n squared, and n*7 would be 7n. This would give you a combined answer of n squared + 7n, or n^2 +7n.
Suppose you make monthly mortgage payments of $1,345 and have 10 years left on the mortgage (next payment due next month). Assuming a 3.6% stated annual interest rate for the mortgage, how much would you need today to pay off the mortgage?
I will need $1,61,884.2 to pay off the mortgage.
This problem is related to simple interest and we have to calculate the amount after 10 years which is payable in the form of mortgage.
The monthly mortgage payment is $1,345.
Rate of interest is 3.6% per annum.
Time is given to be 10 years.
Simple interest for 10 years = 1345×3.6×10/100
= $ 484.2
So, the total money required to clear the mortgage
= $(1345×12×10) + $ 484.2
= $161400 + $484.2
= $ 1,61,884.2

What is the perimeter
of the football poster?
86 cm

greater perimeter?
catam
55 cm
Answer:
1. The perimeter of the basketball poster is 240.
The perimeter of the football poster is 282.
3. Football poster has the greater perimeter.
Step-by-step explanation:
To find the perimeter of the basketball poster you multiply the given side by 4 since there is 4 sides. So 60 * 4 = 240.
To find the perimeter of the football poster you use the formula 2(l+w). So our l (length) is 86, while our w(width) is 86. So plug it in the formula.
2(55+86)=282.
282 > 240, which means that the football poster has a greater perimeter.

When we write numbers on a number line, we can easily compare them and execute simple arithmetic operations on them. A number line's origin is defined as zero (0). The numbers to the left of 0 are all negative, whereas the numbers to the right of 0 are all positive. So, as we walk towards the right on a number line, the value of numbers increases.
A number line includes both positive and negative numbers. A negative number line is formed by the segment of the number line to the left of zero.

Use differences to find a pattern in the sequence.
3,8,15,28,51,88,143
Assuming that the pattern continues, the eighth term should be
Answer:
220
Step-by-step explanation:
You want to use differences to find the pattern and the next term in the sequence 3, 8, 15, 28, 51, 88, 143.
First differencesSubtracting each term from the next, we find the sequence of first differences to be ...
5, 7, 13, 23, 37, 55
Second differencesThe first differences are not constant, so we know the sequence is not linear. They are not in an arithmetic progression, so we know the sequence is not quadratic. They do not have a common ratio, so we know the sequence is not exponential.
The second differences are the differences of the sequence of first differences. They are ...
2, 6, 10, 14, 18
Third differencesThe differences of the terms of the 2nd-difference sequence are constant: 4.
4, 4, 4, 4, 4
Constant 3rd differences mean the original sequence can be described by a 3rd degree polynomial. The coefficients found by a calculator are shown in the attachment.
Next termSince we know the third differences are constant, we can work our way back up the chain of differences to find the next term of the original sequence.
next 2nd difference = 18 +4 = 22
next 1st difference = 55 +22 = 77
next sequence term = 143 +77 = 220
The eighth term should be 220.

AB+ (C x 10) = 97
The values of A, B, and C are mathematically given as
A=48/BB=48/AC=5This is further explained below.
What are the values of A, B, and C?Generally, the equation for the statement is mathematically given as
AB + C = 52
AB+ (C x 10) = 97....1
Using the substitution technique we have
AB = 52- C ....2
Subbing 2 in 1
AB+ (C x 10) = 97
Therefore
52- C + 10C = 97
9C=97-52
9C=45

AB = 52- C
AB = 52- 5

This question: Submit Fritz plans to fence off a square feed lot and then cross-fence to divide it into four smaller feed lots. If he uses 924 feet of fencing, then how much area will be fenced in?
Answer:
23,716 ft
Step-by-step explanation:
Let the side length of each of the four smaller lots be s.
Then, Fritz will use 12s feet, which is equal to 924.
This means s=77.
This means the area of each smaller square is 77²=5929, and thus the total area is 23,716 ft.

Any given equation can be solved with the help of transpose method by following the steps mentioned below, but first understand what is linear equation.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. It is of the form -
y = ax + b
Given a simple equation and we have to solve the equation using transpose method.
We will learn about transpose method of equation solving with the help of an example. Assume that you have to solve the following expression -
4(x + 9) = 3(x + 7)
STEP - 1 - Identify the unknown variable.
In the expression given, the unknown variable is x.
STEP - 2 - Solve the Left hand side and Right hand side to make both sides simpler.
In the expression given, we will simplify both sides -
4(x + 9) = 3(x + 7)
4x + 4 × 9 = 3x + 3 × 7
4x + 36 = 3x + 21
STEP - 3 - Transfer the terms that containing variable one Left hand side of equation and the constant terms on the right hand side.
Apply Step 3 -
4x - 3x + 36 = 21
4x - 3x = 21 - 36
STEP - 4 - Solve for unknown variable.
We have -
4x - 3x = 21 - 36
x = - 15
Therefore, any given equation can be solved with the help of transpose method by following the steps mentioned above.

The governor of state A earns $54,900 more than the governor of state B. If the total of their salaries is $310,850, find the salaries of each
The salaries of each will be 127975 and 182875.
How to compute the value?Lat the salaries of B = b
Let the salary of A = b + 54900
Therefore, we will add them together to get the value:
b + b + 54900 = 310850
2b + 54900 = 310850
2b = 310850 - 54900
2b = 255950
b = 255950/2
b = 127975
a = b + 54900 = 127975 + 54900 = 182875
Therefore, the salaries of each will be 127975 and 182875.
