Answer:
(y - 4)(y + 4)
Step-by-step explanation:
y² - 16 ← is a difference of squares
Since y² and 16 are both squares separated by a difference , that is minus
A difference of squares factors as
y² - 16
= y² - 4²
= (y - 4)(y + 4)
The value of log(0.47) after rounding to 4 decimal place is -0.3279
Option D
Given :
Find the value of log(0.47) using calculator
To find the log value we use the calculator
here we are asked to find out log (0.47) that is the log (decimal)
we cannot find the log value without calculator because we have decimal argument inside log.
Use scientific calculator
Press log first then enter the number 0.47 inside a parenthesis
Press enter , it will show you the log(0.47)
log(0.47) =-0.327902142
Now round the answer to 4 decimal places
We have 0 in the 5th decimal place . so we keep 9 as it is
log(0.47) =-0.3279

Answer:
The solution set is (6,3)
Step-by-step explanation:
Begin by multiplying equation 1 by 2. You'll see why in a moment
2y = 2*(1/2) x
2y = x
Substitute this value into equation 2.
2y + 4y = 18 Combine like terms on the left
6y = 18 Divide both sides by 6
6y/6 = 18/6 Do the division
y = 3
To solve for x just use the top equation
y = 1/2x
3 = 1/2x Multiply by 2
3*2 = x
x = 6
