The x, which is zero in this case will always be the number that goes on the inside of the equation, so far you have y=(x+0)^2 or y=x^2.
The y, which is negative will go on the end of the equation. So you get y=x^2-5
The equation is y=x^2-5 or C if it is multiple choice
The sum of the first n natural numbers and 0=
n*(n+1)/2

solve for "a", to see what Africa's population will then be
<span>–4(x + 3) ≤ –2 – 2x
>>.....-4x -12 </span>≤ -2 -2x
>> -12 +2 ≤ +2x
>> - 10 ≤ 2x
>> -5 ≤ x............>> x >= -5
This answer is not represented in the pictures you attached
The line starts in x = -5 and goes up to infinity
13m 16p
Add three to every number next as well as move up three letters.
For example:
1A is the starting point.
To get from 1A to 4D you add three.
1 + 3 = 4
A to get to D is three letters up.
A b c D
Same thing for 4D to get to 7G.
4 +3 = 7
D to get to G
D e f G
Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.
If you're trying to find the next equation to the puzzle (16p) is your answer.
Hope this helped!:)
