Hi there!
The answer is C.

The question has already revealed the following data:
x = number of tickets.
y = number of t-shirts.
We can now find the total cost function.
The cost of 1 ticket is $ 25
and therefore the total cost for all of the tickets is $25 ×
the amount of tickets, mathematically $25 × x, hence 25x.
The cost of 1 shirt is $ 12
and therefore the total cost for all of the tickets is $12 ×
the amount of shirts, mathematically $12 × y, hence 12y.
When making the total cost function, don't forget to include the service fee of $4.
Now we can conclude that the total cost function is the following:

Maya only has $130 and therefore the total cost must be smaller than or equal to this amount of money. The answer is C.
Answer:
The approximate length of the garden is at least 22 feet and at most 51 feet.
Step-by-step explanation:
A rectangular garden must have a perimeter of 145 feet.
Let x feet be the lengths of the garden. Then the width of the garden can be found using the perimeter:

The area of the garden is

The area must be at least 1,100 square feet, then

Solve this quadratic inequality:
![D=(-72.5)^2-4\cdot 1,100=856.25\\ \\\sqrt{D}=25\sqrt{1.37}\\ \\x_1=\dfrac{72.5-25\sqrt{1.37}}{2}\approx 22\\ \\x_2=\dfrac{72.5+25\sqrt{1.37}}{2}\approx 51\\ \\(x-22)(x-51)\le 0\\ \\x\in [22,51]](https://tex.z-dn.net/?f=D%3D%28-72.5%29%5E2-4%5Ccdot%201%2C100%3D856.25%5C%5C%20%5C%5C%5Csqrt%7BD%7D%3D25%5Csqrt%7B1.37%7D%5C%5C%20%5C%5Cx_1%3D%5Cdfrac%7B72.5-25%5Csqrt%7B1.37%7D%7D%7B2%7D%5Capprox%2022%5C%5C%20%5C%5Cx_2%3D%5Cdfrac%7B72.5%2B25%5Csqrt%7B1.37%7D%7D%7B2%7D%5Capprox%2051%5C%5C%20%5C%5C%28x-22%29%28x-51%29%5Cle%200%5C%5C%20%5C%5Cx%5Cin%20%5B22%2C51%5D)
Answer:
It is a solution
Step-by-step explanation:
y = -4x - 8
Let x = -9 and y = 28
Substitute these values in
28 = -4(-9) -8
28 = 36 -8
28 =28
This is true so it is a solution
The answer is -70
Steps:
1)35( a/35+20)= 18*35
2)35(a/35)+35(20)=18*35
3)35/35a+ 35(20)=18*35
4)35a/35+35(20)=18*35
5)35a/35*700=18*35
6)a+700=18*35
7)a+700=630
8)Subtract 70 both sides
9)Which gives you -70
Hope it helps :))
