Answer:
This statement is "TRUE".
Step-by-step explanation:
Every elementary row operation is reversible. You can get the reverse answer by multiplying by a constant or by multiplying by its inverse. You can add one row to another row and subtract row 1 from row 2 to get it back.
Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.
Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
Well the way you would do it is you would add all of them up and then divide them by how much there is so the numbers added up give you 310 divided by 5 is 62 hop this helps!!!
To solve this problem you must apply the proccedure shown below:
1. You have that a <span>grapefruit is 8% heavier than an orange and an apple is 10% lighter than the orange. Therefore, let's give a value to the orange as following:
Orange=1 kg
2. Therefore, you have:
Grapefruit=1 kg+(0.08x1 kg)=1.08 kg
Apple=1 kg-(0.1x1 kg)=0.9 kg
3. Therefore, what</span><span> percentage is the grapefruit heavier than the apple?
%=(0.9/1.08)100-100
%=16.66%
The answer is:</span>16.66%
