Already restored: 50 houses
Plans to restore: 15 per year, also written as 15T
So, N=15T+50
Answer:
x ≥ -5
Step-by-step explanation:
If we have a translation to left c units, we write " x + c " in the function, and
If we have a translation to right c units, we write " x - c" in the function
If we have vertical translation up b units, we "add b to the function", and
If we have vertical translation down b units, we "subtract b to the function"
The parent function is ![f(x)=\sqrt{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7Bx%7D)
Since translation left 5 units and up 3 units, we can write:
![f(x)=\sqrt{x+5} + 3](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%7Bx%2B5%7D%20%2B%203)
The domain is affected by the square root sign and we know the number under the square root CANNOT be negative, so we can say:
x + 5 ≥ 0
x ≥ -5
This is the domain.
answer: keep, change, flip
but i think its 30/9
Answer:
19
Step-by-step explanation:
8 x 4 = 32
32 + 6 = 38
38 / 2 = 19
A.
y = 20(1.15)^x.....parrots
y = 4x + 24.....snakes
B. after 10 yrs
y = 20(1.15^10)
y = 20(4.05)
y = 81 parrots
y = 4(10) + 24
y = 40 + 24
y = 64 snakes
C.
20(1.15)^x = 4x + 24
x = 6.63 years they will be the same
