<h3>
Answer: -10 and -40</h3>
===============================================================
Explanation:
a = 200 = first term
d = -30 = common difference
Tn = nth term
Tn = a + d(n-1)
Tn = 200 + (-30)(n-1)
Tn = 200 - 30n + 30
Tn = -30n + 230
Set Tn less than 0 and isolate n
Tn < 0
-30n + 230 < 0
230 < 30n
30n > 230
n > 230/30
n > 7.667 approximately
Rounding up to the nearest whole number gets us 
So Tn starts to turn negative when n = 8
We can see that,
Tn = -30n + 230
T7 = -30*7 + 230
T7 = 20
and
Tn = -30n + 230
T8 = -30*8 + 230
T8 = -10 is the 8th term
and lastly
Tn = -30n + 230
T9 = -30*9 + 230
T9 = -40 is the ninth term
Or once you determine that T7 = 20, you subtract 30 from it to get 20-30 = -10 which is the value of T8. Then T9 = -40 because -10-30 = -40.
Answer: 5
Step-by-step explanation:
47+ 16x-4 +12x-3 =180
28x +40 =180
28x = 140
X= 5
Well, if u=12 and you are dividing you would do 144/5 which equals 12. I hope this helps and have a blessed day!
The function rule in slope-intercept form is y = -4x -2
<h3>What is a function ?</h3>
A function is defined as the mathematical statement which defines relation between a dependent variable and an independent variable.
A function f(x) is graphed on the coordinate plane.
The equation for a straight line is given by
y = mx + c
Where m is the slope and c is the intercept on y axis
The intercept on y axis is -2
c = -2
At x = 0 , y =-2
At x = -1 , y =2
m =(2 -(-2))/(-1-0)
m = -4
Therefore ,the function rule in slope-intercept form is y = -4x -2 .
