F ( x ) = 7 x + 2
y = 7 x + 2
- 7 x = - y + 2 /*(-1)
7 x = y - 2 / : 7
x = y/7 - 2/7 = ( y - 2 ) / 7
The inverse of the function is:
f^(-1) ( x ) = ( x - 2 ) /7
Answer : The equation could you use to find p is, 
Step-by-step explanation :
Let the cost of 1 pen be, 'x'
and the cost of 1 pencil is, 'p'
As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:
............(1)
And we have also given that the pen costs twice as much as a pencil. The equation will be:
............(2)
Now put the equation 2 in equation 1, we get:
Thus, the equation could you use to find p is,
Answer:
Hi there!
Your answer is:
$78
Step-by-step explanation:
To set up this equation:
75+ (.04× 75)
Change 4% into decimal format
75+ ( 3)
78

Answer:
The range is { -1,3,7,11,15}
Step-by-step explanation:
The range is just the output values
f(-2) = 4(-2) +7 = -8+7 =-1
f(-1) = 4(-1) +7 = -4+7 = 3
f(0)= 4(0) +7 = 7
f(1) = 4(1) + 7 = 11
f(2) = 4(2) +7 = 8+7 = 15
Answer: 0.512, 0.020, 0.012, 0.002
Step-by-step explanation:
To put these decimals in the order from greatest to least, we first need to make sure they all have the same place values.
0.012, 0.002, 0.020, 0.512
Now that they have the same place values, we can see which is bigger.
0.512, 0.020, 0.012, 0.002
