Answer:
I think it's answer choice A!
Step-by-step explanation:
The reason why I think that it is A is because of the given y values. The x values are consistent through all of the given choices, but if graphed, there is a distance of three units between the y-value of 4 and the y-value of 7. I personally like to use Desmos when it comes to trying to get a visual graph of coordinates. I hope this at least helped a little!
The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units, therefore, option (A) will be correct.
How to find the distance between two points?Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
The distance between with two points (x₁, y₁) and (x₂, y₂) is given as,
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
In option (A),
Points are (2,4) and (2,7).
The distance between them will be,
[tex]d = \sqrt {\left( {2 - 2 } \right)^2 + \left( {4 - 7 } \right)^2 }[/tex]
d = √(3²) = 3
Hence "The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units".

Max puts a stopper in the bathtub and turns on the faucet at t=0. After 5 minutes, there are 11 gallons of water in the tub and after 10 minutes, there are 22 gallons in the tub. Write an equation that relates the number of gallons, g, to the time, t. Does the relationship represent a linear function? Justify your response.
Answers
Answer:
y = 2.2x
Yes, it represents a linear function
Step-by-step explanation:
Given that :
Stopper applied at t = 0
At t = 5 minutes ; water in tub = 11 gallons
At t = 10 minutes ; water in tub = 22 gallons
General form of a linear function :
y = mx + c
Where c = intercept ; m = Slope ; y and x are dependent and independent variables respectively
The intercept = gallon of water at t = 0 ; this is not given and will be taken as 0
Slope = change in y / charge in x
Slope = (22 - 11) / (10 - 5)
Slope = 11 / 5
Slope = 2.2
Hence ;
y = 2.2x + 0
y = 2.2x
Yes, it represents a linear function

Step-by-step explanation:
Step 1: Define Equation
(7x - 1) + (13x - 19) = 180
Step 2: Solve for x
Combine like terms: 20x - 20 = 180Isolate x term: 20x = 200Isolate x: x = 10Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: (7(10) - 1) + (13(10) - 19) = 180Multiply: (70 - 1) + (130 - 19) = 180Subtract: 69 + 111 = 180Add: 180 = 180Here we see that 180 does indeed equal 180.
∴ x = 10 is the solution to the equation.

Which of the following is NOT always true of a function and its inverse?
Answers
The statement that is not always true of inverse functions is (d) f-1(x) is a function
What are inverse functions?Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function
How to determine the statement that is not always true of inverse functions?As mentioned above,
The inverse functions are the opposite of an original equation
This means that:
If a function is f(x), then the inverse if f-1(x)
However, all inverse equation are relations, but not all inverse equations are functions

Tommy went to Taco World and bought 3 tacos and 4 burritos and spent $14.30. Burritos cost twice as
much as tacos. What was the cost of each taco and each burrito?
Answers
If Tommy spent $14.30 and the cost of burritos is twice as much as tacos then the cost of Taco is $1.30 and the cost of burrito is $2.60.
Given that Tommy spent $14.30 and the cost of burritos is twice as much as tacos .
We are required to find the cost of each tacos and burrito.
Suppose the cost of a taco be x and the cost of burrito be y.
Because the cost of burrito is twice as the cost of taco so y=2x.
Total expenditure by Tommy=3x+4*2x
14.30=3x+8x
11x=14.30
x=1.30
y=2*1.3
y=$2.60
Hence if Tommy spent $14.30 and the cost of burritos is twice as much as tacos then the cost of Taco is $1.30 and the cost of burrito is $2.60.

This is an isosceles triangle which mean 2 angles and 2 sides are congruent. In this case, the 3.3 sides corresponds to the 39 degree angle. This means that the other angle next to x angle is also 39 degrees.
39+39= 78
All the angles in the triangle needs to equal 180.
So subtract 78 from 180 to find the degree of x angle.
180-78= 102

As C is the mid-point of BD.
Therefore, BC=DC ...(i)

As two line segments, AE and BD intersect at point C, so the vertically opposite angles are equal.
Therefore, ∠BCA=∠DCE ...(iii)
Now, in ΔABC and ΔEDC,
Angle, ∠BCA=∠DCE [ from equation (iii)]

A bicycle with 28-inch diameter wheels is traveling at 25 mi/h. find the angular speed of the wheels in rad/min.
Answers
The angular speed of the bicycle's wheels that are traveling at 25 mi/h is 1885.7 rad/min
To solve this angular speed problem the formula and the procedure we will use is:
v = w * r
Where:
v = tangential velocityw = angular velocityr = radiusInformation about the problem:
v = 25 mi/hd = 28 inchw = ?Calculating the radius of the wheel, we have:
r = d/2
r = 28 inch/2
r = 14 inch
Converting the velocity unit from mi/h to inch/min, we get:
25 mi/h * (63360 inch / 1 mi) * (1h / 60 min) = 26400 inch/min
Applying the tangential velocity formula and isolating the angular velocity, we get:
v = w * r
w = v / r
w = 26400 inch/min / 14 inch
w = 1885.7 rad/min
What is angular speed?When an object is in uniform circular motion, the angle described by the radius in each unit of time is known as angular speed. It is measured in units of (rad/s) (revolutions/s).

Find a quadratic function that includes the set of values below.
(0,6) (2,12) (3,9)
The equation of the parabola is y= ____
Answers
The quadratic function that includes the set of values is y = -2x^2 + 7x + 6
How to find a quadratic function that includes the set of values?The set of values is given as
(0,6) (2,12) (3,9)
A parabola is represented as
y = ax^2 + bx + c
At (0, 6), we have
6 = a(0)^2 + b(0) + c
This gives
c = 6
So, we have
y = ax^2 + bx + 6
At (2, 12), we have
12 = a(2)^2 + b(2) + 6
This gives
4a + 2b = 6
At (3, 9), we have
9 = a(3)^2 + b(3) + 6
This gives
9a + 3b = 3
Using a graphing tools, we have
a = -2 and b = 7
So, we have
y = -2x^2 + 7x + 6
Hence, the quadratic function that includes the set of values is y = -2x^2 + 7x + 6
