Answer:
-(5x-21)/6 so d
Step-by-step explanation:
to do inverse functions you want to replace the x in the function with y so x=(21-6y)/5, then solve for y and you will get the answer I got and its d

Step-by-step explanation:
In the given image, the line passes through (-1, -1) and (1, 1).
Let the equation of the line is , where m is the tangent of the line and c is a constant.
Putting the co-ordinates of the points in the equation, we get and
From the two equations we get, c = 0 and m = 1.
Hence, the function is y = x.
Domain is .
Range is
I think that this is a power of a power
Your answer is B.
The area of the shaded region will be the area of the circle minus the area of the triangle inside the circle. Then:
The circle has radius 4 cm (distance from the center to the edge of the circle), so the area of the circle is
Now, the area of the triangle is
The base of the triangle is the diameter of the circle (as you can see in the image) and the height is the radius of the circle. Then the are of the triangle is
Finally, the shaded area is = .
The first equation, 8x - 9y = - 23
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = ( , 3) and (x₂, y₂ ) = (- 4, - 1 )
m = = (- 4)/- =
partial equation is y = x + c
to find c substitute either of the 2 points into the partial equation
using (- 4, - 1 ), then
- 1 = - + c ⇒ c =
y = x + ← in slope- intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearrange the slope- intercept equation into this form
multiply through by 9
9y = 8x + 23 ( subtract 9y and 23 from both sides )
8x - 9y = - 23 in standard form
