Answer:

f-¹(x) = -⅕x - ⅘

Step-by-step explanation:

f(x) = -5x - 4 → x = -5y - 4 → 5y = - x - 4 → y = -⅕x - ⅘ → f-¹(x) = -⅕x - ⅘

Answer:

Graph 1: u-v

Graph 2: u-w

Graph 3: w-v

Graph 4: v-u

Step-by-step explanation:

First, let us find u-v, u-w, w-v, v-u.

u-v:

<-2,-7> - <3,-4> = <-2-3,-7-(-4)>= <-5,-3>

u-w:

<-2,-7> - <5,1> = <-2-5,-7-1> = <-7,-8>

w-v:

<5,1> - <3,-4> = <5-3,1-(-4)> = <2,5>

v-u:

<3,-4> - <-2,-7> = <3-(-2),-4-(-7)> = <5,3>

Then we can match the results with the graphs.

Graph 1: u-v

Graph 2: u-w

Graph 3: w-v

Graph 4: v-u

Solve for x and explain

galben [10]

Since the two lines are parallel, the angle labeled 130 is congruent to the angle labeled x+ 136 so you can set them equal to each other

130 = x + 136
subtract 136 from both sides

x = -6

Find the area of the shaded region

PIT_PIT [208]

Answer:

Area of the shaded region= $500inch^2$

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle= $\frac{1}{2}*Base*Height$

$=\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2$

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

$= 30*10\\\\=300 inch^2$

Area of the shaded region= $800-300= 500 inch^2$
