Answer:
x=7
Step-by-step explanation:
5x=35
5x/5=35/5
x=7
Answer:
Yes!
Step-by-step explanation:
first you need two points (x,y) (x,y). 
is the formula you would follow to get the slope. Say you have (2,4) (3,-7) You would plug it into the formula and get 
. This example you can simplify it into -11. hope that kinda helps.
Answer:
(-3,2)
Step-by-step explanation:
This equation is written in vertex from
y = -4(x + 3)2 + 2
Vertex from is
y = a(x - h)2 + k, where vertex is (h,k).
We can rewrite our equation
y = -4(x - (- 3))2 + 2.
So vertex is (-3,2)
Answer:
d(n) = 85 * ( 3 - n )
Step-by-step explanation:
Let's find the common difference of the terms (if any).
The common difference is = 85 - 170 = 0 - 85 = -85 - 0 = -85
For an arithmatic sequence with first term a, common difference d,
nth term = a + ( n - 1 ) * d
So, d(n) = 170 + ( n - 1 ) * (-85)
= 255 - 85n
= 85 ( 3 - n )
