The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours: Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (1 point) Select one: a. The dependent variable is time, the equation is y = 22x, and the dragonfly will travel 528 miles. b. The dependent variable is time, the equation is x = 22y, and the dragonfly will travel 1,056 miles. c. The dependent variable is distance, the equation is y = 22x, and the dragonfly will travel 528 miles. d. The dependent variable is distance, the equation is x = 22y, and the dragonfly will travel 1,056 miles.
Answer:
C
Step-by-step explanation:
The dependent variable is the one on the y-axis which would be distance. This makes sense because the amount of time the dragonfly flies determines the distance it flies. The equation is y = 22x. When x = 24, y = 22 * 24 = 528.
Jada sells her artwork at a trade show. She made $40 on the first day by selling one photograph, one painting, and one necklace. She made $110 on the second day by selling two photographs, three paintings, and three necklaces. She made $50 on the last day by selling one photograph, one painting, and two necklaces. Which system of equations matches Jada's sales at the trade show?
Answer:
x + y + z = 40
2x + 3y + 3z = 110
x + y + 2z = 50
Step-by-step explanation:
let
x = photograph
y = painting
z = neckless
the first part reads that jada sells 1 photograph, 1 painting, and 1 neckless. this written in a mathematical formula will be x + y + z = 40
the second part reads that jada sold 2 photographs, 3 paintings, 3 necklaces. This written as a mathematical formula will be 2x + 3y + 3z = 110
the third part reads that jada sold 1 photograph, 1 painting, and 2 necklaces. this written in a mathematical formulawill be x + y + 2z = 50

Step-by-step explanation:
[tex]y= \frac{-1}{4}x+4[/tex]
Multiply by 4
[tex]4y=4*\frac{-1}{4}x+4*4\\\\[/tex]
4y = -x + 16

Question 6 (5 points)
Solve for the variable x in the equation x + 15 = 62.
Answer: x = 47
Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.
In this problem since 15 is being added to x, in order to get x by itself,
we must subtract 15 from the left side of the equation.
If we subtract 15 from the left side, we must also subtract 15 from
the right side of the equation to keep the equation balanced.
So we have x = 47.
Find the equation of the exponential function represented by the table above
Answer: Y = 3 × 2^x
Step-by-step explanation:
Let assume that the equation of the exponential function represented by the table is
Y = 3(2)^x
When x = 0
Substitute x for 0. Then,
Y = 3 × 2^0
Anything raised to power of zero is equal to one.
Y = 3 × 1 = 3
When x = 1
Repeat the process
Y = 3(2)^1
Y = 3 × 2 = 6
When x = 2
Y = 3(2)^2
Y = 3 × 4 = 12
And finally, when x = 3
Y = 3(2)^x
Substitute x for 3
Y = 3 × 2^3
Y = 3 × 8
Y = 24.
We can therefore conclude that the equation of the exponential function represented by the table above is
Y = 3 × 2^x

Find the equation of the parabola that has a vertex at (2,0) and a y-intercept of (0,12).
Question 8 options:
A)
y = (x – 2)2
B)
y = 3(x – 2)2
C)
y = 3(x + 2)2
D)
y = (x + 2)2
Answer:
C
Step-by-step explanation:
y=3(x-2)² is the equation of the parabola that has a vertex at (2,0) and a y-intercept of (0,12).
what is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.
We have to find equation of the parabola that has a vertex at (2,0) and a y-intercept of (0,12).
Vertex=(2, 0)
y=a(x-2)²
12=a(0-2)²
12=4a
Divide both sides by 4
a=3
Now put a value in above equation
y=3(x-2)²
Hence, y=3(x-2)² is the equation of the parabola that has a vertex at (2,0) and a y-intercept of (0,12).

A quadratic function always has a squared symbol (represented by ^2). The first answer is a linear function, the second answer is a linear function (squaring 0 results in 0, therefore it is canceled out), the third answer has ^2 (this is correct), and the fourth answer has a ^3 (this is a cube function; not quadratic)

If f(x) = 3x and g(x)=1/x
what is the domain of (gºf)(x)?
O x>0
O all real numbers except x=
= 0
X<0
all real numbers
Answer:
Here it is given that f(x)=3x and g(x)=1/x
We have to find the domain of (g o f)(x)
Now it is given that f(x) = 3x
and it is also given that g(x) = 1/x
so (g o f)(x) = g( f(x) ) = g( 3x )
which comes out to be 1 / 3x
The domain of the expression is all the real numbers except where the expression is undefined so the domain of the given expression is all real numbers except 0.
The domain of a function is the set of input values the function can take.
The domain of the function is (b).all real numbers except x = 0
The functions are given as:
[tex]\mathbf{f(x) = 3x}[/tex]
[tex]\mathbf{g(x) = \frac 1x}[/tex]
Calculate (gºf)(x) as follows:
[tex]\mathbf{(g\ o\ f)(x) = g(f(x))}[/tex]
So, we have:
[tex]\mathbf{(g\ o\ f)(x) = \frac{1}{f(x)}}[/tex]
Substitute 3x for f(x)
[tex]\mathbf{(g\ o\ f)(x) = \frac{1}{3x}}[/tex]
For the above function to have a real value, the value of x must not be 0.
Hence, the domain of the function is (b).

Answer:
Yes, he has enough money.
Step-by-step explanation:
I found the heaviest healthy weight for the man which is at 84kg. This means he has to lose 14 kg to be healthy.
Take 14kg divided by 0.75 kg/week to find how many weeks of the diet he needs.
13/0.75 = 18.67 = 18 weeks
Take the number of weeks times the number of calories per week
18 x 600 = 10800
Take this number divided by 200 calories per hour to find the total number of hours.
10800/200 = 54 hours
Take this number times the amount of money per hour.
54 x 6 = 324 This number is less than 360
The countries population in 1992 was 147 million . In 1996 it’s was 153 million. estimate the population in 2008 used The exponential growth formula. Round your answer to the nearest million
Answer:
The population in 2008 is 171 million
Step-by-step explanation:
In order to calculate the population in 2008 using the exponential growth formula we would have to make the following calculation:
population in 2008= population in 1996 + population increased between 1996 and 2008
According to the given data:
population in 1996=153 million
population in 1992=147 million
Therefore, the increase of population from 1992 to 1996=153 million-147 million= 6 million
Therefore, the increase of popoulation is 1 1/2 million each year.
Therefore, if from 1996 and 2008 are 12 years, the population increased between 1996 and 2008= 12 x 1 /1/2 = 18 million.
Therefore, population in 2008=153 million + 18 milliion
population in 2008=171 million
The population in 2008 is 171 million

pound, what is the actual weight range, in pounds, for these bodybuilders (in interval
notation)?
Answer:
the second one, [144,174]
Step-by-step explanation:
since the suits weigh 1 pound, it means the body builders have to weigh one pound less than they normally would to make up for that one pound. therefore, the range is 144 (one less than 145) to 174 (one less than 175)

Which best summarizes the Pythagorean Theorem?
A- The sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse.
B- The length of the hypotenuse of a right triangle is greater than the sum of the lengths of the legs.
C- The sum of the lengths of the legs of a right triangle equals the length of the hypotenuse.
D- For any triangle, the sum of the squares of any two side
lengths is equal to the square
of the third side length.
Answer: A
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
A and B are the legs of the triangle, and c is the hypotenuse. A would make the most sense.
The sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse.
What is Pythagoras theorem?" In a right angled triangle the square of the hypotenuse is equals to the sum of the square of the other two sides of the right angled triangle."
