When a square and a rectangle have the same perimeters. If the length of a side of the square is 4x-1 and  the length of the rectangle is 2x+1 and the width is x+2. then the value of x=1

The perimeter of the square is equal to the perimeter of the rectangle.

The length of a side of the square=4x-1

The perimeter of the square=4a

Where a is the side of the square

Substitute the values in the equation

The perimeter of the square=4(4x-1)=16x-4

The length of the rectangle=2x+1

The width of the rectangle=x+2

The perimeter of the rectangle=2(l+w)

where l is the length and w is the width

The perimeter of the rectangle =2(2x+1+x+2)

=2(3x+3)

= 6x+6

A square and a rectangle have equal perimeters

16x-4=6x+6

16x-6x=6+4

10x=10

x=1

Hence, when a square and a rectangle have the same perimeters. If the length of a side of the square is 4x-1 and  the length of the rectangle is 2x+1 and the width is x+2. then the value of x=1

The complete question is

Answer:

Angle 1 & 2 are both 100 degrees

Step-by-step explanation:

In the picture,

angles on the same side of the line must add up to 180degrees.

Angles directly opposite of each other(same vertices) must be equal.

with parallel lines, angles that are made by the same intersecting line are also equal.

The corresponding values of the lower and upper bounds of m - n are 41.41 and 41.59.

What are the values of the lower and upper bounds of m - n?

Upper and lower bounds are the possible maximum and minimum values of a number before it was rounded.

The upper and lower bounds can be expressed using the error interval

The lowest value of m is 48.15

The highest value of m is 48.24

The lowest value of n is 6.65

The highest value of n is 6.74

Therefore, lower bound of m - n = 48.15 - 6.74 = 41.41

Also, the upper bound of m - n = 48.24 - 6.65  = 41.59

So values of the lower and upper bounds of m - n are 41.41 and 41.59 respectively.

The empty table should be completed with the coordinates of the transformed graph after a dilation with a scale factor of 3 as follows;

x              m(x)

4              -2

2              -1

0              0

-2              1

-4              2

The equation of the resulting line in slope-intercept form is y = -0.5x + 3.

Based on the given coordinates of the graph of function f(x), the dilation with a scale factor of 3 from the origin (0, 0) or center of dilation would be calculated as follows:

Point 1 (-2) → Point 1' (-2 × -2) = Point 1' (4).

Point 2 (-1) → Point 2' (-1 × -2) = Point 2' (2).

Point 3 (0) → Point 3' (0 × -2) = Point 3' (0).

Point 4 (1) → Point 4' (1 × -2) = Point 4' (-2).

Point 5 (2) → Point 5' (2 × -2) = Point 5' (-4).

Next, we would translate the graph of function f(x) 3 units up as follows:

Point 1 (-2) → Point 1' (-2 + 3) = Point 1' (1).

Point 2 (-1) → Point 2' (-1 + 3) = Point 2' (2).

Point 3 (0) → Point 3' (0 + 3) = Point 3' (3).

Point 4 (1) → Point 4' (1 + 3) = Point 4' (4).

Point 5 (2) → Point 5' (2 + 3) = Point 5' (5).

Now, we can determine the slope of the transformed graph:

Slope, m = Δy/Δx

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (2 - 1)/(2 - 4)

Slope, m = -1/2 or -0.5

Mathematically, the slope-intercept form of a straight line is given by;

y = mx + c

Where:

At point (2, 2) and y-intercept c = 3, we have:

y = mx + c

y = -0.5x + 3

Step-by-step explanation:

Joan walked 20 brown dogs.

As per the question, the 40% of total number of dogs are brown. So, finding 40% of the number 50 will give us the number of brown dogs.

Number of brown dogs = 50×40%

Converting Percentage to fraction

Number of brown dogs = 50×40/100

Cancelling zero as it is common

Number of brown dogs = 5×4

Performing multiplication to find the number of brown dogs

Number of brown dogs = 20

The value of f(3) for the given expression is 8.

What is evaluation of an expression?
In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Finding the value of an algebraic expression when a specified integer is used to replace a variable is known as evaluating the expression. We use the given number to replace the expression's variable before applying the order of operations to simplify the expression. The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

Given, the expression is 5(x - 1) - 2
Let y = f(x) = 5(x - 1) - 2 = 5x - 5 - 2 = 5x - 7
Therefore, f(3) using the equation above is: f(3) = 5(3) - 7 = 8
Thus, the value of f(3) or y at x = 3 for the given expression is 8.

The y-intercept and the horizontal asymptote of g(x) = 7ˣ + 2 is (a) (0, 3) ; y = 2

The equation of the function is given as

g(x) = 7ˣ + 2

To calculate the y-intercept, we set x = 0

So, we have

The length is 16.6ft and the width is 8.9ft

Area of the rectangular area = Length × width

A = LW … 1

If he wants to have a rectangular area  of turf with length one foot less than 3 times the width, then

L = 3W - 1 … 2

Substitute 2 into 1

A = (2W-1)W

A = 2W^2 - W

Since area = 150sq.ft

150 = 2W^2 - W

2W^2 - W - 150 = 0

Factorize

2W^2 - W - 150 = 0

W = 1±√1+4(300)/2(2)

W =  1±√1201/2(2)

W = 1±34.655/4

W = 35.655/4

W = 8.91375

W = 8.9 (to nearest tenth)

Get the length

L = A/W

L = 150/8.9

L = 16.85

L = 16.6ft

Hence the length is 16.6ft and the width is 8.9ft

The cups of sugar needed is 2.5 cups.

The cups of flour needed is 3.75 cups

The cups of butter needed is 1.25 cups.

Given the information in the question, the ratio of sugar to flour to butter is 1 : 1.5 : 0.5

Cups of sugar needed = (ratio representing sugar / sum of ratios) x total number of cups

Sum of ratios = 1 + 1.5 + 0.5 = 3

Cups of sugar needed = (1 / 3) x 7.5 = 2.5 cups

Cups of flour needed = (ratio representing flour / sum of ratios) x total number of cups

Cups of flour needed = (1.5 / 3) x 7.5 = 3.75 cups

The range of the function f (x) = -3x are (0, -3, 6).

What is Domain?

The set of all inputs of the function is called Domain of set.

Given that;

The domain of f(x) = -3x is (0, 1, 2).

Now, Domain of the function are the values of x.

So, We find the Range of the function as;

Substitute all the values of domain (x) in the given function as;

The function is;

f (x) = -3x

For x = 0

Range = f (x) = - 3 × 0 = 0

For x = 1;

Range = f (x) = - 3 × 1 = -3

For x = 2

Range = f (x) = 3 × 2 = 6

Step-by-step explanation:

If Shureka Washburn has scores of ​69, 74​, 79​, and 62 on her algebra tests, then by using the inequality, the score she must make on the final exam to pass the course with an average of 71 or higher is 71

The scores she scored on test = 69, 74, 79, 62

Consider the final score she must make on the final exam as x

Sum of the scores = 69+74+79+62+2x

= 284+2x

Consider the average of score = Sum of scores / Number of subjects

= (284+2x)/6

She need average of 71 or higher

Then the inequality equation will be

(284+2x)/6 ≥ 71

284+2x ≥ 426

2x ≥ 426-284
