Answer:
y=2/(x−7)
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x. If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables: x=7+(2/y) for y. y=2/(x-7).
Use the model to solve for x.

Identify the type of function that models the situation below: The cost of mailing a letter is $0.37 for the first ounce and $0.23 for each additional ounce or portion thereof. a. greatest integer function c. absolute value function b. step function
Answer:
The correct option is;
Step function
Step-by-step explanation:
The given information are;
The cost of mailing a letter for the first ounce= $0.37
The cost for each additional ounce = $0.23
Therefore, the cost of mailing a letter can be found from the relation;
y = (N-1) × $0.23 + $0.37
The step function can be represented as follows;
f(x) = a[b(x - h)] + k
Where;
(h. k) = The starting points
a = The vertical step separation
b = The horizontal step separation
Therefore, in the question, we have;
a = $0.23
b = 1
h = 1
k = $0.37
Which gives;
f(x) = $0.23 × [1(x - 1)] + $0.37 = $0.23 × (x - 1) + $0.37
f(x) = $0.23 × (x - 1) + $0.37 which is similar to y = (N-1) × $0.23 + $0.37
Therefore the function that models the situation is step function.

on a school trip, 56 girls and 91 boys go to south Korea they were divided into groups as possible so that each group has an equal number of girls and boy in each group, how many in each group?
Answer:
21
Step-by-step explanation:
You must find a number that will divide into the total of the girls and boys and come up with an even number. By looking at the numbers, you can see that both 56 and 91 will divide evenly by 7. The common denominator for both calculations is 7.
56/7=8 girls
91/7= 13 boys
Add 8 girls and 13 boys and you will have 21 in each group. That way, all groups are equally boys and girls.
8+13=21

The length of a reſtangle is 3 ft more than the width. The perimeter is is 62 ft. Find the length and
width of the rectangle.
Solution:-
Given that length of rectangle is 3 ft more than its breadth . Also , perimeter of rectangle is 62 ft . And we are asked to find the Length and breadth .
So , we know we can find perimeter of rectangle as :
[tex]\boxed{\red{\bf \dag Permiter_{rectangle}=2(l+b)}}[/tex]
Now , let us take the
Breadth be x .Length be x + 3 .So , as per Question :
[tex]\tt :\implies Perimeter=2(l+b)[/tex]
[tex]\tt :\implies 62 \cancel{ft.} = 2( x + 3 + x ) \cancel{ft.} [/tex]
[tex]\tt :\implies 62 = 2 ( 2x + 3 ) [/tex]
[tex]\tt :\implies 62 = 4x + 6 [/tex]
[tex]\tt :\implies 4x = 62 - 6 [/tex]
[tex]\tt :\implies4x = 56. [/tex]
[tex]\tt :\implies x =\dfrac{\cancel{56}}{\cancel{4}} [/tex]
[tex]\underline{\boxed{\red{\tt\longmapsto \:\:x\:\:=\:\:14}}}[/tex]
Hence we got x as 14 .
So , let's put the value in our assumption:
[tex]\boxed{\green{\bf \pink{\dag} Length = x + 3 = 14 + 3 = 17 ft.}}[/tex][tex]\boxed{\green{\bf \pink{\dag} Breadth = x = 14 ft.}}[/tex]8x11=(8x10)+(1x10) how can I make it true?
By applying subtraction property in RHS of the expression, we make it true.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ 8 × 11 = (8 × 10) + (1 × 10)
Now, Take LHS of the expression,
⇒ 8 × 11
⇒ 88
And, By RHS;
⇒ (8 × 10) + (1 × 10)
⇒ (80) + (10)
⇒ 90
Subtract 2;
⇒ 90 - 2
⇒ 88
Thus, By subtracting 2 from RHS of the expression, we make it true.

It’s time to verify that a reflection is a rigid transformation. You’ll begin with the angle measurements. Measure the angles of polygon ABCD and the angles of the reflected image. Record the measure of each angle to the nearest degree.
Answer:
ABCB AGHBGHCGHDGH
90° 90°
45° 45°
135° 135°
90° 90°
Step-by-step explanation:
The measure of each angle of the reflected polygon is same as the corresponding angle of the original one.
What is the reflection of polygon about a line?By reflection about a line, the polygon changes its position such that the distance of every point from the original one will be the same as the distance from every corresponding point of the reflected one from that line.
So according to the question,
Let polygon ABCD is reflected about line GH then the reflected polygon will be A'B'C'D'
Let ∠ABC= 120°
∠BCD= 80°
∠CDA= 70°
∠DAC= 90°
Now if we measure the corresponding angle of the reflected polygon A'B'C'D', then the reflected corresponding angle will be
∠A'B'C'= 120°
∠B'C'D'= 80°
∠C'D'A'= 70°
∠D'A'C'= 90°
Therefore the measure of each angle of the reflected polygon is the same as the corresponding angle of the original one.

find the value of x that makes m parallel to n
Answer:
C. x = 24°
Step-by-step explanation:
(2x+36)° + 4x° = 180° (▼ coordinate angel)
2x°+36°+ 4x° = 180°
2x°+4x° = 180°-36°
6x° = 144°
x° = 144°/6
x° = 24°
In one baseball season, Peter hit twice the difference of the number of home runs Alice hit and 6. Altogether, they hit 18 home runs. How many home runs did each player hit that season.
Answer:
Peter hit 12 home runs and alice hit 6 home runs
Step-by-step explanation:
this is right because if Peter hit 6 and then he hit twice the amount that would bring his total to 12 due to 6 x 2 = 12 and if together they hit 18 home runs that would mean you want to subtract the total from Peter's and that would be explained as 18-12=6 and the 6 left over would leave you with alice number of home runs.

Explain how to use a graph of the function f(x) to
find f(3)
Answer:
find the y-value corresponding to x=3
Step-by-step explanation:
Locate x=3 on the x-axis. Follow a vertical line from that point to the graph of the function. Read from the graph the y-value of the point of intersection of that vertical line and the function. That y-value is f(3).
Answer:
For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.
