True because Plants need Carbon Air to grow. Seashells are made of tiny carbon atoms, Wood is 50% carbon and water is H20 known as Hydrogen and Oxygen. Water DOES have some Carbon in it! It gets the Carbon Dioxide from the rain!
Answer: The slope is 2/3
Step-by-step explanation:
The difference in the rise (y-values) 2, divided by the difference in the run (x-values) 3, is 2/3.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (0, -1)
1 -(-1) ÷ 3 - 0
2 ÷ 3
2/3
Answer:
D=36, x1=1, x2=4
Step-by-step explanation:
Find the D:
D = b2 - 4ac = (-10)2 - 4·2·8 = 100 - 64 = 36
Since the discriminant is greater than zero, the quadratic equation has two real roots
