40 points and brainliest

which function rule describes the pattern in the table?

y= -x-2

Step-by-step explanation:

y=ax+b

x= -2; y=0 => 0=-2a+b; b=2a

x= -1; y= -1 => -1=-a+b => b=a-1

2a=a-1=> a= -1; b= -2

=> y= -x-2

y = -x -2

Step-by-step explanation:

We can find the slope by using 2 points

m = (y2-y1)/(x2-x1)

  = (-3-0)/(1--2)

  = -3/(1+2)

   = -3/3

   = -1

The y intercept is when x=0  The y intercept is -2

y = mx + b where m is the slope and b is the y intercept

y = -x -2

what do u need to know

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
