Using simple multiplication, the cost of 1 1/3 pounds of raspberries equals 12 pounds.
What is multiplication?Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.
Given,
Cost of 3/5 pounds of raspberries = $9
Cost of 1 pound of raspberries = 9 × 5/3
Cost of 1 pound of raspberries = 15 pounds
Cost of 1 1/3 pounds of raspberries = 4/3 × 15
= 12 pounds

5.Given the functions f(x)=-2x + 4 and g(x) = 2x- 8, find the value of x for which f(x) = g(x).
6.Graph the function
The definition of the functions implies that the value of x if f(x) = g(x) is 3
The solution for the value of xThe equations of the functions are given as
f(x) = -2x + 4
g(x) = 2x - 8
This means that, we have the following equation
f(x) = g(x)
Substitute the known values in the above equation
So, we have the following equation
-2x + 4 = 2x - 8
Collect the like terms in the above equation
So, we have
2x + 2x = 8 + 4
Evaluate the like terms in the above equation
So, we have
4x = 12
Divide both sides by 4
x = 3
Hence, the value of x such that the equations are equal is 3

The length of a ruler is 12 inches. There are approximately 25.4 millimeters in 1 inch.
The length of the ruler is approximately 304.8 millimeters .
Length is used to measure distance.
According to the International System of Quantities, length has the dimension of distance. In most measurement systems, length is represented by a base unit from which all other units are derived. The International System of Units (SI) system's fundamental unit of length is the metre.The longest dimension of an object is typically understood to be what is meant by length.However, this isn't always the case depending on the object's position.The length of a fixed object is referred to by a number of names, including height, also referred to as vertical length or vertical extension, and width, breadth, or depth.Given that there are approximately 25.4 millimeters in 1 inch.

The equation of the line in standard form is
(Type your answer in standard form.)
3x + 5y = 15 is the equation of the line in standard form that passes through the point (5,0) and (0,3).
What is the equation of line that passes through the given points?The formula for equation of line is expressed as;
y = mx + b
Where m is the slope and b is the y-intercept.
Given the data in the question;
Point 1 ( 5,0 )
x₁ = 5y₁ = 0Point 2 ( 0,3 )
x₂ = 0y₂ = 3First, we determine the slope of the line.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 3 - 0 )/( 0 - 5 )
Slope m = ( 3 )/( -5 )
Slope m = -3/5
Now, we plug the slope and coordinates of one the point into the equation of line to determine the y-intercept b.
y = mx + b
0 = (-3/5)5 + b
Solve for b
0 = -15/5 + b
0 = -3 + b
b = 3
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (-3/5)x + 3
Convert to standard form; Ax + Bx = C
Multiply each term by 5
y = (-3/5)x + 3
5y = 5(-3/5)x + 5(3)
5y = -3x + 15
Reorder the equation
3x + 5y = 15
Therefore, the equation of the line is in standard form is 3x + 5y = 15.

Volume is 10x3 + 67x2 + 30x − 72, length is 5x − 4, width is 2x + 3
Answer:
height = x + 6
Step-by-step explanation:
Volume = length x width x height
V = 10x³ + 67x² + 30x − 72
length = 5x - 4 and width = 2x + 3
So length x width = (5x - 4 ) x (2x + 3)
Using the FOIL method:
= (5x)(2x) + (5x)(3) + (-4)(2x) + (-4)(3)
= 10x² + 15x - 8x - 12
= 10x² + 7x -12
So to find height, divide Volume by (length x width)
10x³ + 67x² + 30x − 72 ÷ 10x² + 7x -12
Use polynomial long division. See image ( I did the best I could to capture the process)
The answer is x + 6
To verify
Multiply (5x-4) (2x + 3) (x + 6) = 10x³ + 67x² + 30x − 72
The length of a rectangle is 3 cm less than twice the width of the rectangle. If the perimeter is 75 cm, what are the dimensions of the rectangle?
If the length of a rectangle is 3 cm less than twice the width of the rectangle and the perimeter is 75 cm, then the length is 24 cm and width is 13.5 cm
Consider the width of the rectangle as w
The length of a rectangle is 3 cm less than twice the width of the rectangle
The length of the rectangle = 2w-3
Perimeter of the rectangle = 75 cm
Perimeter of the rectangle =2(l+w)
Where l is the length and w is the width of the rectangle
Substitute the values in the equation
2(2w-3+w) = 75
2(3w-3) = 75
6w-6 = 75
6w = 81
w = 13.5 cm
The length of the rectangle = 2(13.5)-3
=24 cm
Hence, If the length of a rectangle is 3 cm less than twice the width of the rectangle and the perimeter is 75 cm, then the length is 24 cm and width is 13.5 cm

Where do you find a vertical shift in the exponential parent function?
What happens when (x-4) is in the exponent?
What happens when (x+9) is in the exponent?
Where do you find a horizontal shift in the exponential parent function?
What happens when there is a +7 at the end of the exponential parent function?
What happens when there is a -6 at the end of the exponential parent function?
For the given expressions we will have:
y = exp(x - 4) →we have a shift of 4 units to the right.
y = exp (x +9) → we have a shift of 9 units to the left.
y = exp(x) + 7 → we have a shift of 7 units up.
y = exp(x) - 6 → we have a shift of 6 units down.
How to work with vertical and horizontal shifts?
Remember that the shifts work as follows.
For a function f(x), we define a vertical shift of N units as:
g(x) = f(x) + N
If N > 0, the shift is upwards.If N < 0, the shift is downwards.For a function f(x), we define a horizontal shift of N units as:
g(x) = f(x + N)
If N > 0, the shift is to the left.If N < 0, the shift is to the right.Then, if we have:
exp(x - 4) we have a shift of 4 units to the right.
exp (x +9) we have a shift of 9 units to the left.
exp(x) + 7 we have a shift of 7 units up.
exp(x) - 6 we have a shift of 6 units down.

Simplifying a ratio of whole numbers: Problem type 1
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.
40 L: 72 L
Answer:
5/9
Step-by-step explanation:
You want the reduced fraction equivalent to the ratio 40L : 72L.
Reduced ratioA ratio is reduced by removing the greatest common factor from all parts of the ratio. Here, that factor is 8L.
40L : 72L = (8L)(5) : (8L)(9) = 5 : 9 = 5/9
The ratio is 5/9.
__
Additional comment
The greatest common factor can be found several ways. The easiest is for you to make use of your knowledge of multiplication tables:
40 = 5·8
72 = 9·8
8 is a common factor. Since 5 and 9 have no common factors, 8 is the greatest common factor of 40 and 72.

What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.
Given equation 8.2x-3.7x = 90
or, 4.5x = 90
or, x = 90/4.5 = 20
Hence, the cost of sheet metal is $20 per sq. feet

What is Limits?
The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are used to define continuity, derivatives, and integrals.
The limit exists only if the value of the limit along every direction that leads to (1,1) is same.
So by calculating,
lim xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2
x->1
calculating the limit along the line x = 1
Similarly,
lim xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2
x->1

And the last limit you calculated is along line y=x.
