find the constant m and b in the linear function f(x)=mx+b so that f(6)=9 and the straight line represents by f has slope -4
Answer:
The constant m=-4, and b=33
Step-by-step explanation:
F(x)= MX+b
If f(6)=9 then x=6, m= -4
9= -4(6) + b
9= -24 + b
b= 9 + 24
b= 33
Therefore the constant m, which is the slope is -4 and b which is the intercept is 33
Given the linear function f(x) = mx + b, we see the slope m as -4. Using the point (6,9), we find the y-intercept b to be 33.
Explanation:In the linear function 'f(x) = mx + b', 'm' represents the slope of the line and 'b' is the y-intercept. As it's given that the slope is -4, we replace 'm' in the equation with -4 to get 'f(x) = -4x + b'. Now, we use the point (6,9) which lies on the line, allowing us to find the value of 'b'. Substituting x = 6 and f(x) = 9 into the equation, we get 9 = -4*6 + b. After solving this equation, we find that b = 33. Therefore, the constants are m = -4 and b = 33.

Julia planet a rectangle garden that is 20 feet long she plays 56 feet of fencing around her Garten what is the width of her Garten what is the area
The width of rectangular garden(b) = 8 feet and
The area of rectangular garden = 160 square feet
Step-by-step explanation:
Given,
The length of rectangular garden(l) = 20 feet and
The perimeter of rectangular garden(fencing) = 56 feet
To find, the width of rectangular garden(b) = ? and
The area of rectangular garden = ?
We know that,
The area of rectangular garden = 2(l + b)
⇒ 2(20 + b) = 56
⇒ 20 + b = 28
⇒ b = 28 - 20 = 8 feet
The width of rectangular garden(b) = 8 feet
∴ The area of rectangular garden = l × b
= 20 feet × 8 feet
= 160 square feet
Hence, the width of rectangular garden(b) = 8 feet and
the area of rectangular garden = 160 square feet
The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet. The calculations were made using the perimeter and area formulas for rectangles.
To find the width of Julia's rectangular garden and its area, we can use the given information:
The garden is 20 feet long, and the total perimeter of the garden is 56 feet.
Step-by-Step Solution:
The formula for the perimeter P of a rectangle is given by:
P = 2L + 2W
where L is the length and W is the width.
We know the following values:
L = 20 feet
P = 56 feet
Substitute these values into the perimeter formula:
56 = 2(20) + 2W
Simplify and solve for W:
56 = 40 + 2W
56 - 40 = 2W
16 = 2W
W = 8 feet
Now we can find the area A of the garden using the formula for the area of a rectangle:
A = L × W
Substitute the values we have:
A = 20 × 8
A = 160 square feet
The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet.

1. How many different sets of 8 songs are possible for Janine's play list? Assume that the
order of the songs doesn't matter.
Answer:
40320
Step-by-step explanation:
the first song on the list could be 8 possible songs;
and the second song on the list could be 7 possible songs after the first one was set;
the third song on the list could be 6 possible songs after the first and second songs were set;;
the fourth song on the list could be 5 possible songs after the first ,second and third songs were set;;
the fifth song on the list could be 4 possible songs after four songs were set;
the sixth song on the list could be 3 possible songs after five songs were set;
the seventh song on the list could be 2 possible songs after six songs were set;
the eighth song on the list could be 1 possible songs after seven songs were set.
so THERE ARE 8X7X6X5X4X3X2X1 DIFFERENT SETS
To calculate the number of combinations, we use the combination formula in combinatorics. However, the total number of songs available is required to provide a specific answer.
Explanation:To determine the number of different sets of 8 songs possible for Janine's play list, we have to use the combination formula of combinatorics. Combinatorics is a branch of mathematics concerning the study of countable or finite discrete structures. The combination is a selection of items where order does not matter. The formula for combination is: C(n, r) = n! / [r!(n-r)!]
where:
'n' is the total number of items (in this case, we don't know the total number of songs available),'r' is the number of items to choose (in this case, 8 songs),'!' denotes a factorial, meaning the product of an integer and all the integers below it, e.g. 4! = 4*3*2*1.Therefore, to answer the question, we would need to know the total number of songs available to Janine. Once we know that, we can substitute that number for 'n', and use the formula to calculate.

Write an equation of the line parallel to y=3x+2 that passes through (-1, -2)
Answer:
[tex]y=3x+1[/tex]
Step-by-step explanation:
From the question, we are given;
The equation y = 3x + 2A point (-1, -2)We are required to determine the equation of a line parallel to the given line and passing through the point (-1, -2)
We are going to determine the gradient of the line first; when an equation is written in the form of y = mx + c, where m is the gradient.y = 3x + 2, m₁ = 3
But, m₁ = m₂ for parallel lines Therefore, the gradient of the line in question, m₂ is 3With the gradient, m₂=3 , and a point (-1, -2) we can get its equation;Taking another point (x, y)...
Then;
[tex]\frac{y+2}{x+1}=3[/tex]

place the numbers 0 to 8, in the magic square so that sum of the numbers in each row, column,and diagonal is the same number, 12
Answer:
[tex]\begin{array}{ccc}1&6&5\\8&4&0\\3&2&7\end{array}[/tex]
Step-by-step explanation:
A magic square can be made by putting the average number in the middle spot. Here, there are 3 numbers in each row, column, or diagonal that total 12, so their average is 12/3 = 4.
There are only 2 pairs of numbers that total 12: (8+4) and (7+5). These must be in the same row and column as the digit 0. If 0 were on a diagonal, we would need three pairs of numbers that total 12, so 0 cannot be on a diagonal.
Our square has 4 in the middle and 0 in a side spot, so it could look like ...
[tex]\begin{array}{ccc}1&6&5\\8&4&0\\3&2&7\end{array}[/tex]
Final answer:
To solve the 3x3 magic square with numbers 0 through 8 adding up to 12, place the numbers strategically so that each row, column, and diagonal sum to the magic constant. One solution involves putting the number 4 in the center and arranging opposite pairs that add to 8 around it.
Explanation:
To place the numbers 0 to 8 in the magic square so that the sum of the numbers in each row, column, and diagonal is the same number, 12, you have to carefully choose where to place each number. A 3x3 magic square using the numbers 0 through 8 is indeed possible with each line adding up to 12. Here's one solution:
2 7 3
6 4 2
4 1 7
Following this pattern ensures that the sum of each row, column, and diagonal line equals 12. Here's the step-by-step process:
Start by placing the number 4 in the middle of the grid, because in a 3x3 magic square, the center is always one-third of the magic constant (12 in this case).
Next, remember that opposite numbers around the center number must be pairs that add up to 8 (since 4 + 8 = 12 which is the magic constant).
Arrange the pairs strategically across the square so that they add up to 12 in each line.
For instance, placing 2 opposite to 6 and 7 opposite to 1 makes sure that rows, columns, and diagonals all sum to 12.

How can u get hundred as a denominator as 209 over 25
Hundred as a denominator as 209 over 25 is obtained by mulyiplying numerator and denominator by 4
[tex]\frac{209}{25} = \frac{836}{100}[/tex]
Solution:
Given that we have to get hundred as a denominator as 209 over 25
Thus the given fraction is:
[tex]\rightarrow \frac{209}{25}[/tex]
Now we have to get 100 as denominator
If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value.
Therefore, equivalent fractions can be created by multiplying or dividing the numerator and denominator by the same number
Muliply and divide by 4, so that 25 muliplied by 4 gives 100
[tex]\rightarrow \frac{209}{25} = \frac{209 \times 4}{25 \times 4} = \frac{836}{100}[/tex]
Thus the denominator is 100

3x + 1.5=2.5x+4.7 is this no solution, 1 solution, or infinite solutions???
Answer:
6.4
Step-by-step explanation:
#1. 3x+1.5=2.5x+4.7
#2. subtract by 1.5 on both sides
#3. 3x=2.5x +3.2
#4. then subtract 2.5x on both sides because you need all the x'x on one side
#5. .5x= 3.2
#6. then you divide but you should bring the decimal to the right once on both sides
#7. x=6.4
The equation 3x + 1.5 = 2.5x + 4.7 has one solution which is x = 6.4.
Explanation:The equation at hand is 3x + 1.5 = 2.5x + 4.7. To check whether the equation has no solution, one solution, or an infinite number of solutions, we have to solve the equation.
By collecting like terms, 3x - 2.5x = 4.7 - 1.5 will give us 0.5x = 3.2. To isolate x, we simply divide both sides of the equation by 0.5, leading to x = 3.2/0.5 which equals 6.4.
Therefore, the given equation has one solution, and that solution is x = 6.4.

Solve the inequality 2n -3 ≥ 5 and graph the solutions
Answer: n ≥ 4
Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation which is to get x by itself on one side of the inequality.
Since 3 is being subtracted from 2n, add 3 to both sides of the inequality to get 2n ≥ 8. Now since n is being multiplied by 2, we need to divide by 2 on both sides of the inequality to get n ≥ 4.
Our next task is to graph n ≥ 4 on a number line and to do that, we start with a closed dot at 4. The reason we use a closed dot at 4 is because not only is n greater than 4 but it's also equal to 4. Next we draw an arrow going to the right on our number line to represent all numbers greater than 4.

What is the inverse of the fuction f(x)= x+3
Answer:
Inverse of function f(x) is y =x-3
Step-by-step explanation:
Given:
f(x) = (x+3)
To Find:
Inverse of f(x)
Solution:
Inverse of the function:
Let f: X -> Y be a function with domain X and target set Y. Then g is the inverse of f if g is a function with domain Y and target set X such that
g(f(x)) = x for all x in X
f(g(y)) = y for all y in Y.
f has an inverse function if and only if f is both one-to-one and onto. If f is one-to-one and onto, then its inverse function g is defined implicitly by the relation g(f(x)) = x.
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
Let y = f(x) = x+3
So, swapping the variables: y=x+3 becomes x=y+3
Now, solve the equation x=y+3 for y.
y=x−3
y=x−3
