Answer:
Equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Step-by-step explanation:
The distributive property says that:
![a \cdot (b+c) = a\cdot b + a\cdot c](https://tex.z-dn.net/?f=a%20%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%20%2B%20a%5Ccdot%20c)
Given the expression: ![9(2a+1)](https://tex.z-dn.net/?f=9%282a%2B1%29)
Apply the distributive property:
![9 \cdot (2a) +9 \cdot 1](https://tex.z-dn.net/?f=9%20%5Ccdot%20%282a%29%20%2B9%20%5Ccdot%201)
Simplify:
![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Therefore, the equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
12. Both sides of the equation are equal and if 18 is half of 36 then 6×2 will give you the value of X
as you already know, we start off by doing a quick switcheroo on the variables, and then we solve for y to get the inverse,
![\bf y=x^2+4\implies \stackrel{switcheroo}{x = y^2+4}\implies x-4=y^2\implies \pm\sqrt{x-4}=\stackrel{f^{-1}(x)}{y}](https://tex.z-dn.net/?f=%20%5Cbf%20y%3Dx%5E2%2B4%5Cimplies%20%5Cstackrel%7Bswitcheroo%7D%7Bx%20%3D%20y%5E2%2B4%7D%5Cimplies%20x-4%3Dy%5E2%5Cimplies%20%5Cpm%5Csqrt%7Bx-4%7D%3D%5Cstackrel%7Bf%5E%7B-1%7D%28x%29%7D%7By%7D%20)
and if you run a vertical line test on that expression, you'll find that it doesn't pass it, meaning is not a function.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Upper level seat = $25
Mid level seat = $40
Number of tickets to give away is at least 25
Budget constraint = $1000
part A: write a system of two inequalities that describe this situation
Number of tickets constraint:
Upper level + mid level ≥ 25
u + m ≥ 25
Cost constraint :
$25u + $40m ≤ $1000
Part B:
Give away 10 upper level seat tickets and 15 mid level seat tickets
Answer:negative 3
