Answer:
(-3+
) /2, (3+) / 2 which is approx -3.791 and 0.791
Step-by-step explanation:
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
Answer: X = -5
Step-by-step explanation:
3(x-5)=2(x-10)
3x - 15 = 2x -20
3x = 2x -5
x = -5
Your answer: -0.8
first you would add all of your temperatures together which would give you -5.6
then you would divide -5.6 by 7 because u have 7 numbers
which would give you your answer!
hope this helps, good luck!
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
