P - m * p - n = p(1 - m) - n
For the first point, remember this simple rule: every exponential function 
always returns 
when evaluated at 
. In fact, 
for every possible base .
So, we can see that the graph of the exponential passes through the point 
where 
appears to be between 1 and 2. So, the only feasible option would be 
, because it passes throught the point 
because 
.
The other functions are wrong because:
would pass through 
, which would be between 0 and 1 on the y axis
would pass through 
, which would be between 2 and 3 on the y axis
would pass through 
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function
means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes
Step-by-step explanation:
-27+√729-504/18=
-27+15/18=
-2/3
To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
