Answer:
28 units
Step-by-step explanation:
• the diagonals of a rectangle are congruent , then
AC = BD , that is
4x - 8 = 2x + 10 ( subtract 2x from both sides )
2x - 8 = 10 ( add 8 to both sides )
2x = 18 ( divide both sides by 2 )
x = 9
Then
BD = 2x + 10 = 2(9) + 10 = 18 + 10 = 28
the diagonals are 28 units long
Write a function $g$g whose graph represents a translation 5 units up of the graph of $f\left(x\right)=3x$f(x)=3x .
The graph when translated 5 units up is g(x) = 3x + 5.
Consider a parent function f(x),
When translating a function up or down by a value (say b), you let g(x) = f(x) + b
If b is positive your graph is translated up, if b is negative your graph is translated down.
When translating a function to the right or left by a value (say a) you let g(x) = f( x + a).
If a is positive your graph is translated to the left, if a is negative your graph is translated to the right.
Therefore, the function g(x) when the graph of the function f(c) = 3x is translated 5 units upwards will be:
g(x) = f(x) + 5
g(x) = 3x + 5
The function g(x) when the graph of f(x) is translated 5 units up is g(x) = 3x + 5.

When the graph of f(x) is translated five units up, the function g(x) becomes g(x) = 3x + 5.
Given function is , f(x) = 3x
We can get,
f(1) = 3(1) =3
f(2) = 3(2) = 6
f(3) = 3(3) = 9
f(0) = 3(0) = 0
f(-1) = 3(-1) = -3
f(-2) = 3(-2) = -6
x 1 2 3 0 -1 -2
f(x) 3 6 9 0 -3 -6
Let us assume, new function is g(x)
Think about the parent function f. (x),
If you want to scale a function up or down by a certain amount, let g(x) = f(x) + b.
Your graph is translated upward if b is positive and downward if b is negative.
Let g(x) Equal f(x + a) when moving a function to the right or left by a certain amount (let's say a).
Your graph will be translated to the left if an is positive and to the right if an is negative.
As a result, when the graph of the function f(c) = 3x is translated 5 units upward, the function g(x) will be as follows:
g(x) = f(x) + 5 (because 5 units up)
We can substitute f(x) value,
g(x) = 3x + 5
Therefore,
The function g(x) when the graph of f(x) is translated 5 units up is g(x) = 3x + 5.

Match the polynomial on the left with the corresponding polynomial on the right.
Add: (-4x²-3x+6) + (6x² - 2x + 1)
Find the opposite of: 2x² + x-7
Subtract: (-4x²+2x-1)-(-2x² + 3x+6)
-2x²-x-7
-2x²-x+7
-2x² - 5x+7
2x²-x+7
2x²-5x+7
(-4x2-3x+6) + (6x2 - 2x + 1) = 2x2-5x + 7, the opposite of 2x2 + x-7 is -2x2 - X+ 7 and (-4x2+2x-1) - (-2x2 + 3x+6) = -2x-x - 7
1. (-4x2-3x+6) + (6x2 - 2x + 1)
= -4x2+ 6x2- 3x- 2x + 1+ 6
= 2x2- 5x + 7
Thus, adding gives us 2x2- 5x + 7 and thus (-4x2-3x+6) + (6x2 - 2x + 1) will be matched with the 5th equation.
2. opposite of: 2x2 + x-7
The opposite of 2x2 + x-7 can be found if we just reverse the signs of each of the term. This means that + becomes - and - becomes -
Thus the opposite is: -2x2 - X+ 7
Thus, it will be matched with the second option.
3. (-4x2+2x-1) - (-2x2 + 3x+6)
= -4x2+2x-1 + 2x2 - 3x - 6
= -4x2+ 2x2 +2x - 3x - 6-1 = -2x-x - 7
Thus, this equation will be matched with the 1st option.

what is the inverse of the function y=5x+30?
The inverse of the function is y = ( 1/5 )x - 6.
An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Consider the function,
y = 5x + 30
To find the inverse of the function we interchange x and y then find the equation for y.
Therefore, after interchanging x and y:
x = 5y + 30
Subtracting 30 from each side of the equation.
x - 30 = 5y + 30 - 30
x - 30 = 5y
Now, dividing the whole equation by 5
( x - 30 ) / 5 = 5y / 5
y = ( 1/5 )x - 30/ 5
y = ( 1/5 )x - 6
Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

57% decrease
130% increase
The percent increase from 200 to 460 is 130% increase
How to find the percent increase or decrease?The numbers are given as
200 and 460.
460 is greater than 200
So, the percentage is an increment
The percentage increment is then calculated as
Percentage = (Final value - Initial value)/Initial value * 100%
Substitute the known values in the above equation
Percentage = (460 - 200)/200 * 100%
Evaluate the difference
So, we have
Percentage = 260/200 * 100%
Evaluate the quotient
So, we have
Percentage = 1.3 * 100%

Which inequality can be used to determine dd, the maximum number of days Taylor can afford to rent for while staying within her budget?
5.5d + 37.93 ≥ 300
5.5 + 37.93d ≤300
5.5 + 37.93d ≥ 300

The time needed to roast a chicken depends on its weight. Allow at least 20 min/lb for a chicken weighing as much as 6 lb . Allow at least 15 min/lb for a chicken weighing more than 6 lb .
a. Write two inequalities to represent the time needed to roast a chicken.
The two inequalities are:
y = 20x when x ≤ 6 and y = 15x when x > 6
The scenario given here is of a chicken that is being roasted. To solve this problem, we will take y as the time required to roast the chicken and x as the lbs of the chicken. (weight)
Now two different conditions are applied depending upon the lbs of the chicken the taken to roast the chicken will vary,

If a square has a perimeter of 36 cm,
how long is each side of the square?
b) The following shape is made by cutting an
equilateral triangle from a rectangle.
Find its perimeter.
7.2 cm
13 cm
a) Each side of the square is 9 cm long. b) The perimeter of the shape is 18 cm.
What is perimeter?Perimeter refers to the total length of the boundary or outer edge of a two-dimensional shape.
a) The perimeter of a square is the sum of the lengths of all its sides. Since all sides of a square are equal, we can divide the perimeter by the number of sides to find the length of one side:
Perimeter of square = 4 x Length of one side
36 cm = 4 x Length of one side
Divide both sides by 4:
Length of one side = 36 cm / 4 = 9 cm
Therefore, each side of the square is 9 cm long.
b) To find the perimeter of the shape made by cutting an equilateral triangle from a rectangle, we need to add up the lengths of all its sides.
The length of the rectangle is equal to the length of the base of the equilateral triangle plus the length of one of its sides. Since the equilateral triangle has all sides equal, we can find its length by dividing the length of the rectangle by 2:
Length of equilateral triangle = Length of rectangle / 2
Length of equilateral triangle = 7.2 cm / 2 = 3.6 cm
The perimeter of the equilateral triangle is three times its side length:
Perimeter of equilateral triangle = 3 x Length of one side
Perimeter of equilateral triangle = 3 x 3.6 cm = 10.8 cm
The perimeter of the shape is the sum of the length of all its sides, which is the sum of the length of the rectangle and the perimeter of the equilateral triangle:
Perimeter of shape = Length of rectangle + Perimeter of equilateral triangle
Perimeter of shape = 7.2 cm + 10.8 cm = 18 cm
Therefore, the perimeter of the shape is 18 cm.

Write a recursive formula for each sequence. 1,4,9,16, . . . . . . .
The recursive formula for sequence 1,4,9,16, . . . is a(n) = 2 a(n-1) - a(n-2) + 2
The recursive formula of a sequence is a formula that relates the nth term of the sequence with the preceding term(s), (n-1)th, (n-2)th, and so on.
The given sequence is: 1,4,9,16, . . .
So, we must ask ourselves:
How can we get 4 from 1?
How can we get 9 from 4 and 1?
and so on.
Notice that:
4 = 1 + 3
9 = 4 + 5
16 = 9 + 7
Notice that the differences (3, 5, 7) increase by 2.
Therefore, we can write:
4 = 1 + 3
= 1 + (1 - 0) + 2
9 = 4 + (4 - 1) + 2 (9 is a(3), and 4 is a(2))
a(3) = a(2) + a(2) - a(1) + 2
= 2 a(2) - a(1) + 2
16 = 9 + (9 - 4) + 2
a(4) = a(3) + a(3) -a(2) + 2
a(4) = 2 a(3) - a(2) + 2
