First we need to factor the left side. Since it is a perfect square (as is the process with completing the square, we know we can take half of the middle number along with x to be in the two parenthesis.
(x - 4)(x - 4) = 25
Now we simplify to show it as a square.
(x - 4)^2 = 25
Next we take the square root of both sides
x - 4 = +/- 5
Note that we have plus or minus 5. This is because either square would give us positive 25. Now we add 4 to both sides
x = 4 +/- 5
4 + 5 = 9
4 - 5 = -1
Answer:
1 / 4c+5
Step-by-step explanation:
Given :
4c + 5 ≠ 0
c is a real number.
Find the multiplicative inverse of equation ?
The multiplicative inverse of a number is reciprocal of number
Let
x = a number
The multiplicative inverse = 1/x
Let 4c + 5 ≠ 0 be a number x
Then, the multiplicative inverse of x = 1/x
x = 4c + 5
1/x = 1 / 4c+5
Therefore, the multiplicative inverse of 4c + 5 = 1 / 4c+5
90x+60y=72
60y=-90x+72
y=-1.5x+1.2
then create a graph using this formula.
