6 0

Answer:

f^-1(x)= 9x+117

Step-by-step explanation:

hello :

let f(x) = y  so : y = 1/9 x-13

calculate : x       you have : 1/9x= y+13  so : x= 9(y+13)=9y+117

If f(x)=1/9x-13, then f^-1(x)= 9x+117

What is angle M? Just checking work
Artist 52 [7]
Sum of interior angles = 180
180 - 60 = 120

120/4 = 30
m<L = m<A = 60
m<M = 30
m<C = m<N = 3(m<M) = 3(30) = 90

Find the equation of the line with Slope = 8 and passing through (3,28). Write your equation in the form
kvasek [131]

Answer:

y = 8x + 4

Step-by-step explanation:

y=mx+b

m=8

y = 8x + b

We just need to find b. B is where the line intersects the y- axis. On the y-axis by definition, the x-coordinate =0 but that is not helpful now...

Let's re write and try to solve for b. That means write as b = ...

y = 8x + b

b = y - (8x)

Substitute for x and y the numbers of the coordinates of the given point (3,28):

b = y - (8*x)

b = 28 - (8*3)

b = 28 - 24

b = 4

So the answer is y = 8x + 4

Write the equation that describes the line with slope = -8 and y -intercept = 2 in slope -intercept form (y=Mx+b).
Mrac [35]

Answer:

y=-8x+2

Step-by-step explanation:

The reason that is the answer is because the slope-intercept form is y=mx+b where m is the slope and b is the y-intercept so y=mx+b would be y=-8x+2
