Gerald is going mini golfing at Golf-O-Rama with his family. For his family of 5 to play it costs $34. They were charged for three student tickets and two adult tickets. If a student ticket costs 3/4 as much as an adult ticket costs, how much does one student ticket cost?
Answers
Answer:
The cost of one student ticket = $6
Step-by-step explanation:
They were charged for three student tickets and two adult tickets.
Let the cost of one student ticket = a
Let the cost of one Adult ticket = b
If a student ticket costs 3/4 as much as an adult ticket costs
a = 3/4(b)
= 3b/4
For his family of 5 to play it costs $34.
Hence:
3a + 2b = $34
a = 3b/4
3(3b/4) + 2b= 34
9b/4+ 2b = 34
9b + 8b / 4 = 34
17b/4 = 34
17b = 34 × 4
b = 136/17
b = $8
The cost of one Adult ticket = $8
Note that:
a = 3b/4
a = 3(8)/4
a = 24/4
a = $6
Therefore, the cost of one student ticket = $6

Is (1, 5) a solution to the following system of equations? Show and explain why or why not.
[tex]f(x)=3x+2[/tex]
[tex]g(x)=[x-1]+1[/tex]
Answers
Answer:
The solution(s) to a system of equations is the point(s) of intersection.
To find the solution, equate the equations and solve for x to find the x-coordinate:
[tex]\implies f(x)=g(x)[/tex]
[tex]\implies 3x+2=[x-1]+1[/tex]
[tex]\implies 3x+2=x[/tex]
[tex]\implies 2x=-2[/tex]
[tex]\implies x=-1[/tex]
Now substitute the value of x into one of the equations to find the y-coordinate of the solution:
[tex]f(-1)=3(-1)+2=-1[/tex]
So the solution to this system of equations is (-1, -1)
Therefore, (1, 5) is NOT a solution to the system of equations.
Let's check

Put (1,5)[tex]\\ \rm\rightarrowtail 5=3+2[/tex]

What is the end behavior of f(x) ? plz help!
Answers
Answer:
D
Step-by-step explanation:
The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.
Let's take a look at each end.
As x approaches negative infinity:
We can see from the graph that as x approaches negative infinity (a.k.a as x goes towards the left), the graph is curving upwards.
Therefore, as x approaches negative infinity, f(x) approaches positive infinity.
Therefore, the end behavior of the left is:
[tex]\text{As } x\rightarrow -\infty, f(x)\rightarrow\infty[/tex]
As x approaches (positive) infinity:
We can see from the graph that as x approaches positive infinity (as x is moving towards the right), the graph f(x) is curving downwards.
Therefore, as x approaches positive infinity, f(x) approaches negative infinity.
Therefore, the end behavior of the left is:
[tex]\text{As } x\rightarrow\infty, f(x)\rightarrow-\infty[/tex]
So, our answer is D.
And we're done!

Answers
Answer:
Step-by-step explanation:
Sum of interior adjacent angle is 180 degrees.
Given
m∠BNR=12w-19,
m∠RNA= ¼(w+199)
m∠BNA=2(12w-19).
Substitute
m∠BNR+m∠RNA=

Brandon has 36000 to invest and wants to earn 5% interest per year. He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year. How much money should he put into each account so that he earns 5% annually
Answers
Answer:
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500
Step-by-step explanation:
Interest = Principal × Rate × Time
Let x = money saved in account A
Let y = money saved in account B
Brandon has 36000 to invest and wants to earn 5% interest per year
x + y = 36000..... Equation 1
x = 36000 - y
He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year.
Hence:
4.4% × x × 1 + 6% × y × 1 = 36000 × 5% × 1
0.044x + 0.06y= 1800....... Equation 2
Substitute 36000-y for x in Equation 2
0.044(36000 - y) + 0.06y = 1800
1584 -0.044y + 0.06y = 1800
-0.044y + 0.06y = 1800 - 1584
0.016y = 216
y = 216/0.016
y = 13500
Note that:
x = 36000 - y
x = 36000 - 13500
x = 2250
Therefore,
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500
