Answer:

A₍ₙ₎ = - 74 + (n-1) x 6

Step-by-step explanation:

A₍ₙ₎ = A₍₁₎ + (n-1) x d

A₍₁₈₎ = 28 = A₍₁₎ + 17 x d  ..... (1)

A₍₄₀₎ = 160 = A₍₁₎ + 39 x d  .....(2)

(2)-(1)    132 = 22d

d = 6

A₍₁₎ = 28 - 17 x 6 = -74

formula: A₍ₙ₎ = - 74 + (n-1) x 6

(5,9), (5-3)<br> what is the slope?
monitta

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you want to find out what the slope is, you have to remember what the formula is first....

m=\frac{y}{x} =\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

so in this case -3 would be the y_{2} because it's the y in the ordered pair and it's the second one. Then one of the 5's would be x_{2} and 9 would be y_{1} and then the other 5 would be x_{1}.

now if we plug it in

\frac{-3-9}{5-5} =\frac{-12}{0}

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.

What is the total area of the figure below? ​
ki77a [65]

Answer:

D

Step-by-step explanation:

28×14=392, which generally already gives you the answer. But the extra area is a trapezoid so we do 4+6=10×2(height)=20, but we have to divide by two since its a trapezoid giving us 10. So 10+392=402

I need help finding the slope
grin007 [14]

answer:
-1

work:

y = mx+ b

so we can tell that the Y intercept is 1, so we can plug that in. ( + b is the y-intercept)

y = mx + 1

plug in some values to find the slope.
(-1, 2)
2 = -m + 1
- 1       - 1

1 = -1m 
/-1   /-1

-1 = m
the slope is -1.

i hope this helps! :D
