Answer:
n = 30
Step-by-step explanation:
Rearrange this to make it easier:
115 - 85 = n
30 = n
Answer:
4
Step-by-step explanation:
in base 4
21 = (2 * 4) + (1 * 1) = 9

Answer:</h2>
Step 1: Determine the formula.
y - y₁ = m(x - x₁)
Step 2: Determine what variables you need.
(x₁,y₁) = a point on the line
m = slope
Step 3: Plug each number in for the variables and you have the completed point-slope form of the equation for the line.

The point-slope form of this line is:
.
See the image for the formula I used.
28y-16y=12y

Answer:
a = 1
b = 3
c = 1
d = 2
e = 6
f = 8
Step-by-step explanation:
Any integer with power as zero = 1
<h3>
For a</h3>
2^x
2^0
= 1
<h3>
For b</h3>
3 * 2^x
3 * 2^0
3 * 1
= 3
<h3>
For c</h3>
2 ^ 3(x)
2 ^ 3(0)
2 ^ 0
= 1
<h3>For d</h3>
2^1
= 2
<h3>
For e</h3>
3 * 2^x
3 * 2^1
3 * 2
= 6
<h3>For f</h3>
2 ^ 3(x)
2 ^ 3(1)
2 ^ 3
2 * 2 * 2
= 8
