Answer:

Step-by-step explanation:
Explicit Geometric Formula: 
a₁ is 1st term
<em>r</em> is common ratio
<em>n</em> is term number
Step 1: Find common ratio <em>r</em>
r = 10/2 = 5
Step 2: Plug variables into formula

Hello there!
4x² = 100
We wanna start by dividing both sides by 4
4x²/4 = 100/4
x² = 25
Now we can take square root
x = +/-√25
x = 5 or x = -5
As always, it is my pleasure to help students like you!
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
The answer should be X equal 5
Answer:
0.2y+10
