If \displaystyle xx is the price of a child ticket in dollars and \displaystyle yy is the price of an adult ticket in dollars, write a system of equations that models this situation and then solve it to find out how much each type of ticket costs.
Answer:
Children ticket cost $30 and adult ticket costs $40.
Step-by-step explanation:
Given that:
x = price of a child ticket
y = price of an adult ticket
According to given statement;
3x+2y=170 Eqn 1
4x+6y=360 Eqn 2
Multiplying Eqn 1 by 3
3(3x+2y=170)
9x+6y=510 Eqn 3
Subtracting Eqn 2 from Eqn 3
(9x+6y)-(4x+6y)=510-360
9x+6y-4x-6y=150
5x=150
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{150}{5}\\x=30[/tex]
Putting x=30 in Eqn 1
3(30)+2y=170
90+2y=170
2y = 170-90
2y = 80
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{80}{2}\\y=40[/tex]
Hence,
Children ticket cost $30 and adult ticket costs $40.

Answer:
I think its uh
Step-by-step explanation:
the first= it is. f= 3x+3/x^2
the second= it is. f= x-3/x^2
sorry if this is wrong btw, i tried my best U-U
Answer:
they're not inverses.
Step-by-step explanation:
the inverse of f(x)= 3/x +3 would be f(x) 3 / x-3
for the second equation the inverse of that one would be h(x) = -3/ x-1

the length of a rectangle is 7m more than its width.If the width is 3m,determine the perimeter and the area
Answer:
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Solve for x: 3500=700*2^8x Check all that apply.
3500=700 \times 2 ^ { 8x }
\frac{3500}{700}=2^{8x}
5=2^{8x}
2^{8x}=5
\log(2^{8x})=\log(5)
8x\log(2)=\log(5)
8x=\frac{\log(5)}{\log(2)}
8x=\log_{2}\left(5\right)
x=\frac{\log_{2}\left(5\right)}{8}
[tex]\text{The \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)} \text{\ for the \textbf{equation},}\ 3500=700\times 2^{8x}.[/tex]
So, option c) and d) are correct.
Logs with base a, they are called Common Logs and Logs with base e are called Natural Logs.
[tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]
Given equation:
[tex]3500=700\times 2^{8x}\\[/tex]
In order to solve it for x first take logarithm both sides of the equation as follows:
We can take log natural as well as common log
1. taking common log:
[tex]log(3500)=log(700\times 2^{8x})\\log(3500)=log(700)+log( 2^{8x})\\log(3500)-log(700)=8x\ log( 2)\\\\log\dfrac{3500}{700}=8x\ log( 2)\\\\log5=8x\ log2[/tex]
Evaluating x as follows:
[tex]x=\dfrac{\log(5)}{8\log(2)}[/tex]
2. Similarly on taking natural log:
[tex]x=\dfrac{\ln(5)}{8\ln(2)}[/tex]
[tex]\text{Thus, the \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)}[/tex][tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]

Answer:
[tex]Q=(9,11)[/tex]
Step-by-step explanation:
Solving (4a)
[tex]P (x_1,y_1) = (1,1)[/tex]
[tex]M (x,y) = (5,6)[/tex]
Required
Determine [tex]Q(x_2,y_2)[/tex]
To do this, we make use of the mid-point formula:
[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Substitute values for x, y, x1 and y1
[tex](5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2})[/tex]
Multiply through by 2
[tex]2 * (5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2}) * 2[/tex]
[tex](10,12) = (1+x_2,1+y_2)[/tex]
By comparison:
[tex]10 = 1 + x_2[/tex]
[tex]x_2 = 10 - 1[/tex]
[tex]x_2 = 9[/tex]
[tex]12 = 1 + y_2[/tex]
[tex]y_2 = 12 - 1[/tex]
[tex]y_2 = 11[/tex]
Hence, the coordinates of Q is (9,11)

How many solutions does 2x-4=4-2x have?
Answer:
8/4 or 2
Step-by-step explanation:
2 solutions
The equation 2x - 4 = 4 - 2x has a single solution, x = 2.
The equation 2x - 4 = 4 - 2x can be simplified and analyzed to determine the number of solutions.
First, let's simplify the equation by combining like terms:
4x - 4 = 4
Next, we can add 4 to both sides of the equation to isolate the variable:
4x - 4 + 4 = 4 + 4
This simplifies to:
4x = 8
Now, we divide both sides of the equation by 4 to solve for x:
(4x) / 4 = 8 / 4
This yields:
x = 2
Therefore, the equation 2x - 4 = 4 - 2x has a single solution, x = 2.
This means that when we substitute x = 2 into the original equation, both sides will be equal. Thus, the equation has a unique solution, indicating that the two sides of the equation represent the same line or point of intersection.
In summary, the equation has one solution, which is x = 2.
