If there are 775 then the answer is 124 I believe or maybe this for points
Answer:
16.5+13.6+12.4.17.7= 60.2
60.2÷4 =15.05
Answer:
<h2>
y = x² - 1</h2>
Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of every given point we get the squares of x-coordinate:
(1, 0): 1² - 1 = 0
(2, 3): 2² - 1 = 4 - 1 = 3
(3, 8): 3² - 1 = 9 - 1 = 8
(4, 15): 4² - 1 = 16 - 1 = 15
So for any x:
(x, y) y = x² - 1
2(5n-2)=4(n+2)
10n-4=4n+8
6n-4=8
6n=12
n=2
