The inverse function as g⁻¹ (h) = [(h+6)/10]² which is the correct answer would be an option (E).
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To determine the inverse of a function, all you have to do is switch where h and g are and resolve for g.
So after switching h and g,
g = g(h) = 10√h - 6
becomes
h = 10√g - 6
Now, we solve for h regularly.
h + 6 = 10√g
(h + 6)/10 = √g
[(h+6)/10]² ⇒ g = [(h+6)/10]² = g(x)
Therefore the inverse of g(x) is g⁻¹ (h) = [(h+6)/10]²
Hence, the inverse function as g⁻¹ (h) = [(h+6)/10]²

Here are 2 polygons. Select all sequences of translations, rotations, and reflections below that would take polygon Pto polygon Q
The required sequences are The first pair is rotated and translated, the second pair is reflected and translated, and the third pair is reflected and translated.
What is translation?Translation means the displacement of a figure or a shape from one place to another. In translation a figure can move upward, downward, vertical and horizontal.
Some of the Translation are,
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure.
Rotation means the circular movement of an object around a centre. It is possible to rotate different shapes by an angle around the centre point.
Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system.

Write an equation of the line through each pair of points in slope-intercept form.
(2,-1) and (2,6)
The equation x = 2
is the slope-intercept form of the line passing through the points (2,-1) and (2,6)
It is given that, the line is passing through two points (2, -1) and (2, 6)
The formula to find the equation of a line in two point form is
(y-y1) = [tex]\frac{y2 - y1}{x2 - x1}[/tex](x-x1)
where m = [tex]\frac{y2 - y1}{x2 - x1 }[/tex] is the slope of the line
Slope is the measurement of the level of steepness of the line
We need to find the Two- Point form of the line
Using the above formula we get, where
x1 = 2 , x2 = 2, y1 = -1, y2 = 6
m = [tex]\frac{(6-(-1))}{(2-2)}[/tex]= [tex]\frac{7}{0}[/tex]
The equation of the line = (y-y1) = [tex]\frac{y2 - y1}{x2 - x1}[/tex](x-x1)
[y - (-1)] = [tex]\frac{7}{0}[/tex] (x - 2)
0. [y - (-1)] = 7(x-2)
7x - 14 = 0
x = 2

The rectangle on the right is a scaled copy of the rectangle on the left. Identify the
scale factor. Express your answer as a whole number or fraction in simplest form.
Answer: Scale factor = 5/4 and this is a fraction number.
Step-by-step explanation:
Given Data,
find the question in the attachment.
Scale factor = (Dimensions of image) / (corresponding dimensions of preimage)
Let us assume,
Dimensions of image = B
corresponding dimensions of preimage = A
So,
we can write,
Length of rectangle B = 45/2
Length of rectangle A =18
Then,
Scale factor = B/A
= (45/2) / (18)
= 22.5 / 18
= 5/4
= 1.25
Therefore, image rectangle A is dilated with by a scale factor of 1.25
1.25 as a fraction is expressed as 5/4In order to express 1.25 as a fraction, we will first try to remove the decimal.
As 1.25 has 2 numbers after the decimal point, we will divide it by 100 in order to remove the decimal.
Hence, we get: 1.25 = 125/100
Now, dividing both sides by a common factor of 25, we will get:
125/100 = 5/4
Thus, 1.25 a as a fraction is 5/4.
Therefore,
Scale factor = 5/4 and this is a fraction number.

Mark and Heather Starr are celebrating their 25th anniversary by having a reception at a local reception hall. They have budgeted $4,500 for their reception. If the reception hall charges a $60 cleanup fee plus $36 per person, find the greatest number of people that they may invite and still stay within their budget.
Answer:
123 people
Step-by-step explanation:
60 + 36x ≤ 4500 x is the number of people
36x ≤ 4440 Subtract 60 from both sides of the equation
x ≤ 123.333... Divide both sides by 36.
We cannot have a portion of a person, so we would round down to the next person which would be 123.

Carolyn needs to figure out the missing properties used to simplify the expression below
The properties used in the the simplification of the expression is:
step 1: Inverse multiplication property
step 2: Commutative property
step 3: Associative property
step 4: Commutative property
step 5: Identity property
Given the expression is:
1 ÷ 2/3 × (₋5) × 3 ÷ (₋1/4)
step 1: 1 × 3/2 × (₋5) × 3 × (₋4)
Inverse multiplication property is applied.
The reciprocal of a particular integer is referred to as the multiplicative inverse. It is employed to make mathematical expressions simpler. The word "inverse" denotes an opposing or opposed action, arrangement, position, or direction. A number becomes 1 when it is multiplied by its multiplicative inverse.
step 2: 1 × (₋4) × 3/2 × (₋5) × 3
Commutative property is applied.
Mathematical addition and multiplication operations are covered under the commutative property. In other words, adding or multiplying two integers does not change the outcome if the order or location of the numbers is changed.
step 3: 1 × [(₋4) × 3/2] × (₋5) × 3
Associative property is applied.
According to the associative feature of multiplication, the outcome of a multiplication problem is unaffected by the arrangement of the numbers in the problem's constituent parts.
step 4: 1 ×[-6] × (₋5) × 3
commutative property is applied.
step 5: (-6) × (₋5) × 3
Identity property is applied.
Multiplying 1 by any number yields the number itself, according to the Multiplicative Identity Property, commonly known as the Identity Property of Multiplication. This is because any time a number is multiplied by 1, it retains its identity and does not change.
Hence we have applied the above mentioned properties of multiplication.

What is the slope of the line 5y+3 = (2/5)x ?
The slope of the line 5y + 3 = (2/5)x is 2 .
The equation of a straight line can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is 5y + 3 = (2/5)x .
To get the slope of this given equation we need to convert the given equation in the format of equation of a straight line i.e., equation1.
So, now we will rearrange the given equation as,
5y + 3 = (2/5)x
⇒ 5y = (2/5)x - 3
Now on dividing this equation by 5 on both sides, we will get
⇒ y = 2x + (-3/5) equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 2
Intercept = c = (-3/5)
The slope of the line 5y + 3 = (2/5)x is 2 .

Answer:
a score of 100 is required
Step-by-step explanation:

average = [tex]\frac{sum}{count}[/tex]
given her average for 4 subjects is 80 , then
[tex]\frac{sum}{4}[/tex] = 80 ( multiply both sides by 4 to clear the fraction )
sum = 320
let x be the score required to raise average to 84 , then
[tex]\frac{320+x}{5}[/tex] = 84 ( multiply both sides by 5 )
320 + x = 420 ( subtract 320 from both sides )
x = 100

The property of real numbers illustrated by the equation is commutative property of multiplication.
The basic properties of real numbers are used to determine the sequence of simplifying mathematical expressions.
Commutative property of multiplication states that change order of factors does not change the product. i.e. a*b=b*a.
In the given equation, to determine if the property is applicable, we need to rewrite the equation:
97(7)=100(7)-3(7)
Taking the common factor out on the right side:
97(7)=7(100-3)
Simplifying,
97(7)=7(97)
Both sides of the equation will give the same answer of 679.

You invested $10,000 in two accounts paying 2% and 5% annual interest, respectively. If the total interest earned for the year
was $290, how much was invested at each rate?
***
At 2 % annual interest, the amount invested was $ 7,000 and at 5 % annual interest, the amount invested was $ 3,000.
Total amount invested = $ 10, 000
interest earned = $ 290
Let amount invested for 2 % annual interest = x
Let amount invested for 5 % annual interest = 10,000 - x
so, we get that:
2 % x + 5 % (10,000 - x) = 290
0.02 x + 500 - 0.05 x = 290
500 - 0.03 x = 290
0.03 x = 500 - 290
0.03 x = 210
3 x = 21000
x = 21000 / 3
x = 7,000
10,000 - x = 3,000
Therefore, at 2 % annual interest, the amount invested was $ 7,000 and at 5 % annual interest, the amount invested was $ 3,000.
