Jamal drew the function below. Which explains whether or not his function is linear?
A)It is linear because it has a constant rate of change.
B)It is linear because it does not have a constant rate of change.
C)It is not linear because it has a constant rate of change.
D)It is not linear because it does not have a constant rate of change.
Answers
*the function drawn by Jamal is the attachment below
Answer:
A) It is linear because it has a constant rate of change.
Step-by-step explanation:
When you plot all the coordinates of a linear function on a graph, the line that passes through all the points plotted is typically a straight line. There would be absence of any curve or bends. All you'd have is a straight line.
Consequent on this, a straight line indicates that the rate of change remains the same along the line slope.
If you pick any two points on the line and calculate the rate of change, it would give you the same rate of change you'd get when you calculate the rate of change of another two points on the line.
A straight line indicates a constant rate of change. Therefore, the function drawn by Jamal is a linear function because it has a constant rate of change.

A submarine left Diego Garcia traveling east 5 hours before an aircraft carrier. The aircraft carrier traveled in the opposite direction going 10 km/h faster than the submarine for 2 hours after which time the ships were 110 km apart. Find the submarine's speed
Answers
Answer:
40km/hStep-by-step explanation:
Let the submarine's speed be x km/h
the time taken by the submarine is given as 5 hours
the aircraft travels 10km/h faster than the submarine= 15km/h
time taken by the aircraft is 2hours
therefore the distance covered by both vehicles can be described using the expression below
we know that distance=velocity*time, so equating the two vehicles distance to 110km we have
5*x+15*2=110
5x+30=110
solving for x we have
5x=110-30
5x=80
divide both sides by 5 we have
x=80/5
x=40km/h
The submarine's speed is 40km/h

A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas
tank, the driver got on a highway and drove for a while.How many miles has the car traveled if it has 10 gallons of gas left in the tank?
and write an equation that represents the relationship between the distance the car has traveled in mikes, d, and the amount of gas left in the tank in gallons, x
Answers
Answer:d=(16-x)30
Step-by-step explanation:
The car traveled 600 miles if it has 10 gallons of gas left in the tank.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
To determine the equation that represents the relationship between the distance traveled by car and the amount of gas left in the tank.
Let the distance traveled by car would be d miles,
and the amount of gas left in the tank would be x gallons
Since the car had a 16-gallon fuel tank
So the amount of gas left in the tank would be 16 - x
When driven on a highway, it has a gas mileage of 30 miles per gallon.
To find the equation of the distance we have to calculate the product of gas left in the car and the mileage of the car.
So the required equation as:
⇒ d = (16-x)30.
If it has 10 gallons of gas left in the tank
Substitute x = 10 in the above equation, we get
⇒ d = (16-10)30.
⇒ d = (20)30.
⇒ d = 600.
Therefore, the car traveled 600 miles if it has 10 gallons of gas left in the tank.

The x intercepts are (-5, 0) and (2, 0)
The y intercept is (0, -10).
Step-by-step explanation:
The x intercepts are (-5, 0) and (2, 0)
When you set the numbers x + 5 and x - 2 equal to zero, you solve for x and that becomes the x-intercept.
The y intercept is (0, -10).
When you multiply the numbers, you result in [tex]x^{2} +3x - 10[/tex].
Then, set the x values to 0 and evaluate. That leaves you with -10, which is the y-intercept.

Carolyn and her basketball team are traveling form Oak City to the beach for the championships. The distance to the beach is about 1,344 miles. The team plans to drive 50 miles per hour. About how many hours will it take for Carolyn and her team to get to the beach?
Answers
Answer:
It will take 26.88hours to get to the beach
Step-by-step explanation:
From the problem statement, we are asked to find the time required to reach the beach.
given data
distance s=1344 miles
speed v= 50 mph
time t=?
we know that the relationship between speed, distance and time is given as
velocity=distance/time
substituting our given data into the expression we have
50=1344/t
making t subject of the formula we have
t=1344/50
t= 26.88 hours
Therefore it will take 26.88hours to get to the beach
A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number line to show the change in position of the sea turtles from depth it was swimming. What integer represents the sea turtles change in position?
Answers
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.

Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:
i. Statements b and d would map Shape l onto Shape II
ii. Statements a, c, e, and f does not map Shape l onto Shape II
What is transformation?Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation. The translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased. Thus the answers to the question are listed as follows:
a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 6 units. Does not Map Shape l onto Shape II
b. a 90° clockwise rotation about the origin and then a translation left 6 units Answer: Maps Shape l onto Shape II
c. a 90° counterclockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation left 6 units.
d. Does not Map Shape l onto Shape IId. a 90° clockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation right 4 units Answer: Maps Shape l onto Shape II
e. a 180° rotation about the origin, followed by a reflection across the y-axis, and then a 90° clockwise rotation about the answer of the origin: Does not Map Shape l onto Shape II
f. a reflection across the y-axis, followed by a 90° counterclockwise rotation about the origin, and then a translation right 4 units. Does not Map Shape l onto Shape II.

In the figure shown below, if line m is parallel to line n, then find the value of x
Answers
Answer:
Step-by-step explanation:
The two angles shown are considered "alternate interior angles" because they lie on the INSIDE of two parallel lines, but on alternate/opposite sides of the transversal line. Alternate interior angles are congruent. You can use transformations to see that they are congruent. Therefore, you should set the two expressions equal to each other and solve for x.
The value of x is 25.
Given,
Line m is parallel to line n
The figure has two alternate interior angles.
- (2x - 10)°
- (65 - x)°
We need to find x.
What does Alternate Angles Theorem says?It states that when two parallel lines are cut by a transversal the resulting alternate interior angles or alternate exterior angles are congruent.
We have ,
From the figure:
Two alternate interior angles.
- (2x - 10)°
- (65 - x)°
Since line m and line n are parallel and from the alternate angles theorem
we see that,
2x - 10 = 65 - x
2x + x = 65 + 10
3x = 75
x = 75/3
x = 25
Thus the value of x is 25.

Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Answers
Answer:qsq
Step-by-step explanation:
Answer:
Step-by-step explanation:
The answer to this is 1 or 7:
To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.
Next, we subtract 50 from both sides of the equation.
Next, we divide both sides of the equation by 10
Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.
Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x
Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x
Therefore, x, the number of measures of music played, must be either 1 or 7.
