If the length L of a rectangle is 3 less than twice the width W, which of the following gives the length of the
rectangle in terms of the of the width
Answer:
L = 2W - 3
Step-by-step explanation:
If the length L of a rectangle is 3 less than twice the width W, then
L = 2W - 3
The expression for the length L of a rectangle is L = 2W - 3.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
The length L of a rectangle is 3 less than twice the width W can be expressed as:
L = 2W - 3
Therefore,
The length of the rectangle can be found by taking twice the width and subtracting 3 from the result.

If you are performing the following translation (x,y) --> (x + 3, y -4) Determine how that would change the original ordered pair (10, 9). Select the new ordered pair after the Translation. (answer choices below)
(7, 9)
(10, 4)
(3, 10)
(13, 5)
Answer:
(13, 5 )
Step-by-step explanation:
The translation
(x, y ) → (x + 3, y - 4)
Means add 3 to the x- coordinate and subtract 4 from the y- coordinate, so
(10, 9 ) → (10 + 3, 9 - 4 ) → (13, 5 )

Step-by-step explanation:
Answer:
x = - 1, x = 2
Step-by-step explanation:
Given
x + (x + 1) + (x + 2) = (x + 1)² ← expand using FOIL , then
x + x + 1 + x + 2 = x² + 2x + 1 , that is
3x + 3 = x² + 2x + 1 ( subtract 3x + 3 from both sides )
0 = x² - x - 2 ← in standard form
0 = (x - 2)(x + 1) ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 2 = 0 ⇒ x = 2

because the expression is raised to a power, you're going to multiply the power inside the expression with the power outside the expression. Thus:
[tex] \frac{10 ^{20} }{10^{12} } [/tex]
Since the powers are being divided, you can just subtract 20 by 12. Then you would get:

m∠ABC = (9x + 4)° and m∠DEF = (13x − 22)°. If ∠ABC and ∠DEF are supplementary, what is the measure of each angle?
Answer:
∠ABC measures 85° and ∠DEF measures 95°.
Step-by-step explanation:
We are given that ∠ABC and ∠DEF are supplementary. Then by definition:
[tex]\displaystyle m\angle ABC + m\angle DE F = 180^\circ[/tex]
Substitute:
[tex]\displaystyle \left(9x+4\right) + \left(13x-22\right) = 180[/tex]
Solve for x. Combine like terms:
[tex]22x -18 = 180[/tex]
Add:
[tex]\displaystyle 22x = 198[/tex]
And divide. Hence:
[tex]\displaystyle x = 9[/tex]
To find the measure of ∠ABC, substitute and evaluate:
[tex]\displaystyle \begin{aligned}m\angle ABC &= 9x + 4 \\ &= 9(9) + 4 \\ &= 81 + 4 \\ &= 85^\circ \end{aligned}[/tex]
And:
[tex]\displaystyle \begin{aligned}m\ngle DE F &= 13x - 22 \\ &= 13(9) - 22 \\ &= 117-22 \\&= 95^\circ \end{aligned}[/tex]
In conclusion, ∠ABC measures 85° and ∠DEF measures 95°.

The correct function that represents this data is option A. f(x) = -5x - 2.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given are three functions in the option.
We have a set of points on the table.
We have to find which function is representing the table.
Input values are the x values and the output values are the y values.
From the table, the y value corresponding to the x value of 0 is -2.
Substitute in each of the function.
A. f(x) = -5x - 2
= 0 - 2
= -2
B. f(x) = -5x + 7
= 0 + 7
= 7
C. f(x) = -5x + 2
= 0 + 2
= 2
The function in A is the only function which got the value as -2 when x = 0.
Hence the function is represented in option A. f(x) = -5x - 2.

Sum of the maximum and minimum values of y=2cos^2 x + 3sin^2 x + 5
To begin with, we can simplify y using the Pythagorean identity:
y = 2 cos²(x) + 3 sin²(x) + 5
y = 2 (cos²(x) + sin²(x)) + sin²(x) + 5
y = 2 + sin²(x) + 5
y = sin²(x) + 7
Next, we can further rewrite this using the half angle identity for sine:
y = (1 - cos(2x))/2 + 7
y = 15/2 - 1/2 cos(2x)
Now, since cos(x) is bounded between -1 and 1, we have
max(y) = 15/2 - 1/2×(-1) = 15/2 + 1/2 = 8
and
min(y) = 15/2 - 1/2×1 = 15/2 - 1/2 = 7
Then the sum of the maximum and minimum is 8 + 7 = 15.

the round trip distance between City X and City Y is 647 miles. A national park is between City X and City Y, and is 27 miles from City X. Find the round trip distance between the national park and city Y. Justify your answer.
The round trip distance between the national park and city Y is 593 miles.
Given:
Round trip distance from City X and City Y = 647 milesDistance between City X and national park = 27 milesTo find :
The round trip distance between the national park and city Y
Solution:
According to the question, the round trip distance between City X and City Y is 647 miles.
Let the distance from City X to City Y = d
Let the distance from City Y to City X = d
[tex]d+d=647 miles\\2d=647 miles\\d=\frac{647miles}{2}=323.5 miles[/tex]
Distance from City X to City Y = 323.5 miles
Distance of City X from national park = 27 miles
From the figure, the distance of the national park from the City Y = d -27 miles:
[tex]= 323.5 miles - 27 miles = 296.5 miles[/tex]
The distance from national park to City Y = 296.5 miles
When we will be going on the round trip between the national park and city Y we will be first traveling 296.5 miles from the national park to the City Y and then 296.5 miles from City Y to the national park.
So, the round trip distance between the national park and city Y:
[tex]296.5 miles + 296.5 miles = 593 miles[/tex]
So the round trip distance between the national park and city Y is 593 miles.
