Replace f(x) with y
Y = 2x -5
Swap roles of x
X= 2y-5
5+x =2y
Divide by 2
5+x /2 = y
Replace y with inverse f^-1(x)
Answer= f^-1(x) = 5+x / 2
Answer:
y = -3x + 22
Step-by-step explanation:
In this question, we have to make an equation with the given information.
First, we need to find the slope using the slope equation: m = y2-y1/x2-x1
Solve for the slope by plugging in coordinates:
m = 16 - 7/2 - 5
m = 9/-3
m = -3
Now, we know that the slope of the line is -3.
We have to find the y-intercept of the equation, to do this, we would plug in some of our given information to the y = mx + b equation.
We would use our slope (-3) and one of the coordinates to solve for b.
Solve:
7 = -3(5) + b
7 = -15 + b
Add 15 to both sides.
22 = b
We now know that our y-intercept is 22. Now we can gather all of our new information to make our equation:
y = -3x + 22
The equation of the line is y = -3x + 22
Answer:
The result after partial products of 89 x 38 is 3382
Step-by-step explanation:
We need to solve 89 x 38 using partial products.
In Partial products we divide each term such that 89 can be written as 80 and 9 while 38 can be written as 30 and 8
We will multiply each term with other and then find their sum.
Multiplication is shown in figure attached.
Now adding the results of each cell in the table:
2400+640+270+72= 3382
So, the result after partial products of 89 x 38 is 3382.

Answer:
$190
Step-by-step explanation:
you just have to add all the numbers up- 62.89+48.26+81.99 which is about 193 so you would round down
X = -2 or lesser than that
So x = < -2
