Answer:
1. =
2. <
3. <
Step-by-step explanation:
Note: When comparing decimals you always place both decimals right above each other.
1 is equal to because once you put a 0 behind the 2.1 they are both the same.
2.10
2.1 <add 0 as space holder
2 is less than because they are both negative you are looking for which one is closest to zero.
-4.5 <add 0 as place holder
-4.25 <closest to zero
3 is less than because (pie) equals 3.141592654 which is less than 3.2.
3.141 <do not need to add whole decimal
3.2 <add two 0's as a placeholder

Answer:
y = -(x+1)^2 +3
Step-by-step explanation:
Translating f(x) left by 1 unit replaces x with x+1.
Translating f(x) up by 3 units replaces f(x) with f(x)+3.
Reflecting f(x) over the x-axis replaces f(x) with -f(x).
__
When y = x^2 is reflected over the x-axis, it becomes ...
y = -x^2
When y = -x^2 is translated 1 unit left, it becomes ...
y = -(x +1)^2
When y = -(x+1)^2 is translated 3 units up, it becomes ...
y = -(x +1)^2 +3
Answer:
The cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
Step-by-step explanation:
Let each pound of trail mix cost dollars and each pound of jelly beans cost
dollars.
Given:
7 pounds of trail mix and 9 pounds of jelly beans cost $ 37.
So, --------------- 1
Also, 5 pounds of trail mix and 3 pounds of jelly beans cost $ 17.
So, --------------- 2
Multiplying equation 2 by -3, we get
Now, adding equations 1 and 3, we get
Now, plug in in equation 1 and solve for
.
Therefore, the cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
