Answer:

x = 32

Step-by-step explanation:

The sum of all interior angles of this pentagon is 540

Solve for x by using this formula

540 = (180-71)+(180-85)+(180-44)+(180-3x)+(180-2x)

540 = 700 - 5x

540 - 700 = -5x

-160 = -5x

-160/-5 = x

32 = x

Slope = -2/5 y-intercept= 0
densk [106]

Answer:

y=(-2/5)x

Step-by-step explanation:

Assuming that the goal is to find the linear equation in slope-intercept form, this problem is pretty simple.

Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. We just have to plug in the information

y=(-2/5)x+0

Simplifies to:

y=(-2/5)x

Please worth 20 points
lianna [129]

Answer:

100 in = 180 out

107 in = 187 out

117 in = 197 out

Step-by-step explanation:

we know that when there was 102 in, there was 185 out. we can also see that when there's 105 in, there was 185 out. the system outputs the input + 80

100 + 80 = 180

107 + 80 = 187

117 + 80 = 197

Help please thank you!
Dmitry_Shevchenko [17]

Answer:

g(f(x)) = x

Yes, the functions are inverses.

Step-by-step explanation:

Hi there!

We're given:

f(x) = 8x-7

g(x)=\displaystyle\frac{x+7}{8}

To solve for g(f(x)), plug f(x) into g(x) as x:

g(f(x))=\displaystyle\frac{(8x-7)+7}{8}\\\\g(f(x))=\displaystyle\frac{8x-7+7}{8}\\\\g(f(x))=\displaystyle\frac{8x}{8}\\\\g(f(x))=x

Because g(f(x)) = x, the two functions are inverses.

I hope this helps!
