Determine the solution to f(x) = g(x) using the following system of equations: (5 points) f(x) = 3x − 23 g(x) = −4.5x + 7
Answers
Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
Please help ! ;v; A coordinate plane is shown. A line passes through the point (-4,1) and through the y-axis at 4. What is the y-intercept of the line shown?
Answers
Answer:
(0, 4)
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis when x = 0. Since you are given the graph, you can see that when x = 0, the graph crosses y = 4, so our y-int is (0, 4).
Find the y-intercept of the line on the graph

Answer:
The answer to this is y=4
Step-by-step explanation:
The answer is the point at which the line intercepts the y-axis.
Hope this helped. :)
Answer: The y intercept is 4.
Step-by-step explanation:
The y intercept of a line is when the x coordinate is 0. So looking ate the line you could see that y is 4 when x is 0. Or in common terms we will write it as (0,4) .So the y intercept is 4

Answers
Answer:
The 1095 represents the amount of transactions already processed.
Step-by-step explanation:
Since this equation is showing us the number of transactions added over time, we know that in A = P(1 + r)^t,
A is the total amount
P is the starting amount
r is the rate
t is the time
So, our 1095 matches with P, and is the starting amount of transactions.

A taut string of length 10 inches is plucked at the center. The vibration travels along the string at a constant rate of c inches per millisecond in both directions.

A. | x -5 | =0. 3 B. ∣cx−5∣=0.3 C. | x -0.3 | = 5 D. | x - 10 | =0.3c
Answers
Answer:
The correct option is
[tex]A. \ \dfrac{1}{c} \times \left | x - 5 \right | = 0.3[/tex]
Step-by-step explanation:
The parameters given are;
The length of the string = 10 inches
The speed or rate of travel of the wave = c inches per millisecond
The position on the string from the left-most end = x
The time duration of motion of the vibration to reach x= 0.3 milliseconds
The distance covered = Speed × Time = c×0.3
Given that the string is plucked at the middle, with the vibration travelling in both directions, the point after 0.3 millisecond is x where we have;
The location on the string where it is plucked = center of the string = 10/2 = 5 inches
Distance from point of the string being plucked (the center of the string) to the left-most end = 5 inches
Therefore, on the left side of the center of the string we have;
The distance from the location of the vibration x (measured from the left most end) to the center of the string = 5 - x = -(x -5)
On the right side of the center, the distance from x is -(5 - x) = x - 5
Therefore, the the equation that can be used to find the location of the vibration after 0.3 milliseconds is [tex]\dfrac{1}{c} \times \left | x - 5 \right | = 0.3[/tex] or [tex]\left | x - 5 \right | = 0.3 \times c[/tex] which gives the correct option as A

The rate of interest required is %.
(Round to two decimal places as needed.)
Answers
Answer :
13%
Step-by-step explanation:
Compound interest which is compounded annually calculated using the formula :
A = I( 1 + r/100)^t
Where I = invested amount
r = interest rate ; t = period ; A = final amount
If period = 9years, the rate required to triple the investment equals;
The final amount = 3 * invested amount = 3I
We now have ;
3I = I( 1 + r/100)^9
Divide both sides by I
3 = (1 + r/100)^9
Take the 9th root of both sides
3^(1/9) = (1 + r/100)^(9*1/9)
3^(1/9) = 1 + r/100
r/100 = 3^(1/9) - 1
r/100 = 1.1298309 - 1
r / 100 = 0.1298309
Multiply both sides by 100
r = 12.98309
r = 12.98 = 13%

Answer:

Step-by-step explanation:
Alright, geometric probability.
We need to find
the area of the rectanglethe area of the equilateral triangle the area of the square the area of the part of the circle that does not include the squareand the area of the part of the rectangle that does not include the square, circle, or triangle.To find those, we need to find the areas of:
the outer rectanglethe circlethe equilateral trianglethe squareLet's start off with the easiest figure. The circle.
The circle has a radius of 10. Therefore, its area is is π[tex]r^2[/tex]. 100π is roughly 314.159265.
The circle has an area of around 314.159265.
Half of the diagonal of the square is 10m. That means that the full diagonal of the square is 20 m.
Formula for side of square using diagonal:
a = q / √2
20/√2 = 14.142135623731
The area of a square is a^2
14.142135623731^2= 200
The area of the square is 200 m^2. (28)
Using this, and the area of the circle, we can find the area of the part of the circle that does not include the square.
314.159265 - 200= 114.159265
The area of the part of the circle that does not include the square is 114.159265.
Now, the most important calculation (because it lets us find the total area of the rectangle); the equiangular triangle.
The height of this triangle is 30m. Therefore, the area is 519.6152422706632.
The area of the equiangular triangle is 519.6152422706632.
The side length of the equiangular triangle is 34.64101615137755.
The area of the rectangle= l times w.
l = 34.64101615137755
w= 30
30 times 34.64101615137755= 1039.23048454133
The total area is 1039.23048454133.
Now that we have the denominator of our fraction (total area), lets go back to our questions.
We need to find
the area of the equilateral triangle the area of the square the area of the part of the circle that does not include the squareand the area of the part of the rectangle that does not include the square, circle, or triangle.The area of the equilateral triangle = 519.6152422706632
519.6152422706632/1039.23048454133 = .5
The geometric probability that a point chosen randomly inside the rectangle is inside the equilateral triangle is .5
The area of the square = 200
200/1039.23048454133 = 0.19245008973
The geometric probability that a point chosen randomly inside the rectangle is inside the square is 0.19245008973
The area of the part of the circle that doesn't include the square: 114.159265
114.159265/1039.23048454133= 0.10984980396
The geometric probability that a point chosen randomly inside the rectangle is inside the part of the circle that doesn't include the square is 0.10984980396
The part of the rectangle that doesn't include the square, circle or triangle.
Area of triangle = 519.6152422706632
(The triangle contains the circle and square).
1039.23048454133- 519.6152422706632 = 519.61524227067
519.61524227067 /1039.23048454133 = 0.5
The geometric probability that a point chosen randomly inside the rectangle is inside the part of the circle doesn't include the square, circle, or triangle is 0.5

At the movie theatre, child admission is S5.20 and adult admission is $8.30. On Tuesday, 156 tickets were sold for a total sales of S1087.10. How many adult
tickets were sold that day?
Answers
Answer:
So, 89 Adult tickets were sold.
Step-by-step explanation:
So, we first name our variables, say, a for number of adult tickets, and c for child tickets.
Then we write our system of equations, first the total $ sale:
5.2c + 8.3a = 1087.10
Then we write the 2nd equation, the total number of tickets:
c + a = 156
Now, we can solve the system:
We do have different methods, let's to by subsitution.
make some change to the 2nd equation, to make c the subject: c = 156 - a
Now we plug that into the 1st equation:
5.2(156 - a) + 8.3a = 1087.10
811.2 - 5.2a + 8.3a = 1087.10
811.2 + 3.1a = 1087.10
3.1a = 275.9
a = 89
The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V and five-sevenths represent?
Answers
Answer:
The answer is explained below
Step-by-step explanation:
Given that The volume of air inside a rubber ball with radius r can be found using the function V(r) = [tex]\frac{4}{3}\pi r^3[/tex], this means that the volume of the air inside the rubber ball is a function of the radius of the rubber ball, that is as the radius of the rubber ball changes, also the volume of the ball changes.
As seen from the function, the radius is directly proportional to the volume of the ball, if the radius increases, the volume also increases.
[tex]V(\frac{5}{7} )[/tex] is equal to the volume of the ball when the radius of the ball is [tex]\frac{5}{7}[/tex]. Therefore:
[tex]V(\frac{5}{7} )=\frac{4}{3} \pi *(\frac{5}{7} )^3=1.53\ unit^3[/tex]
