Answer: The man was worse off than in 2005
Step-by-step explanation:
Assume the man's salary in 2005 was $4,500.
In 2006 therefore, his salary goes to:
= 4,500 * (1 + 10%)
= $4,950
In 2007, this drops by 10%:
= 4,950 * ( 1 - 10%)
= $4,455
<em>The man was worse off than in 2005 because the 10% reduction was based on the larger 2006 salary but the 10% increase was based on the smaller 2005 salary. </em>
Answer:
The inverse of f(x)=3x+1 is f(x)−1=13x−13
Step-by-step explanation:
Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
Answer:
72/5
Step-by-step explanation:
18/5 x4 = t/4 x4
(18x4)/5 = t
t = 72/5
