Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.

The inverse of the function f(x) is equivalent to -
f ⁻¹(x) = 7(3 - x).
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the function -
f(x) = 3 - x/7
The given function is -
f(x) = 3 - x/7
we can write -
y = 3 - x/7
Replace [y] and [x], as follows -
x = 3 - y/7
y/7 = 3 - x
y = 7(3 - x)
f ⁻¹(x) = 7(3 - x)
Therefore, the inverse of the function f(x) is equivalent to -
f ⁻¹(x) = 7(3 - x).

Answer:

Step-by-step explanation:
Linear equation
A line with the slope of 1/2 pass through the point (3,-2)
a) Write the equation of the line in Point - Slope Form.
b) Write the equation of the line in Slope - intercept form.
Answers
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (3, - 2) , thus
y - (- 2) = [tex]\frac{1}{2}[/tex] (x - 3) , that is
y + 2 = [tex]\frac{1}{2}[/tex]( x - 3) ← in point- slope form
(b)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form

Answer:
m∠CEH = 79°
Step-by-step explanation:
From the picture attached,
∠CED and ∠CEH are the pair of linear angles.
Since, pair of linear angles are supplementary angles.
m∠CED + m∠CEH = 180°
101° + m∠CEH = 180°
m∠CEH = 180° - 101°
= 79°
Therefore, measure of angle CEH is 79°.

Step-by-step explanation:
Jason age will be 63 years.
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
The condition is given as;
'' Jason says that 10 less than one third of his age is 11 years old. ''
Now,
Let age of Jason = x years
Then, By the given condition we formulate;
1/3 x - 10 = 11
Solve for x as;
1/3 x - 10 = 11
Add 10 both side;
1/3 x - 10 + 10 = 11 + 10
1/3 x = 21
Multiply by 3;
x = 63
Thus, Jason age will be 63 years.

Arabica coffee costs $28 per pound and Robusta coffee
costs $8.75 per pound. How many pounds of Arabica coffee
must you mix with 3 pounds of Robusta coffee to make a
blend that costs $15.50 per pound?
Answers
Answer:
1.62 pounds
Step-by-step explanation:
Let x be the pounds of Arabica
Take the number of pounds times the cost of each of the coffees individually
This must be equal to the number of pounds times the cost together
x * 28 + 8.75 *3 = ( x+3) 15.50
28x+26.25=(x+3)15.50
Distribute
28x+ 26.25 = 15.50x + 46.50
Subtract 15.50x from each side
28x-15.50x +26.25 = 15.50x +46.50-15.50x
12.50x + 26.25 = 46.50
Subtract 26.25 from each side
12.50x +26.25-26.25 = 46.50-26.25
12.50x = 20.25
Divide each side by 12.5
12.5x/12.5 = 20.25/12.5
x =1.62

The school that Danielle goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234. The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets. What is the price each of one adult ticket and one student ticket?
Answers
Answer:
Price of Adult tickets =$ 13
Price of student tickets =$ 8
Step-by-step explanation:
Lets us represent the price of adult tickets = x
The price of student tickets = y
On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.
= 10 × x + 13 × y = $234
= 10x + 13 y = 234
The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.
5 × x + 4 × y = $97
= 5x + 4y = 97
Hence:
10x + 13y = 234......Equation 1
5x + 4y = 97......... Equation 2
We solve by elimination method
Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x
10x + 13y = 234......Equation 1 × 5
5x + 4y = 97......... Equation 2 × 10
50x + 65y = 1170......Equation 3
50x + 40y = 970..... Equation 4
Subtract Equation 4 from Equation 3
25y = 200
y = 200/25
y = 8
Therefore the price of student ticket = $8
Note that
5x + 4y = 97......... Equation 2
5x + 4 × 8 = 97
5x = 97 + 32
5x = 65
x = 65/5
x = 13
Therefore price of adult tickets = $13
