D. 1010.37 km ! blah blah blah blah b
Answer:
-1
Step-by-step explanation:
-8(-1) + 2y = 8
8 + 2y = 8
2y = 0
4(-1) + 3y = -4
-4 + 3y = -4
3y = 0
Answer:
9 cm
Step-by-step explanation:
First, we need to find the volume of the cylindrical water bottle. The volume of a cylinder is πr²h where r = radius and h = height. In this case, r = diameter / 2 = 6.5 / 2 = 3.25 and h = 21 so the volume is π * 3.25² * 21 = 221.8125π ≈ 696.84. Let's call the length of the cubic container s. The volume of the cube (which is s³) must be at least the volume of the water bottle, therefore:
s³ ≥ 696.84
∛s³ ≥ ∛696.84
s ≥ 8.86566
The smallest integer value that satisfies this is 9 cm.
Answer:
y = -2/5x - 6
Step-by-step explanation:
Slope intercept follows the y = mx + b, which m is the slope, and b is the y intercept.
1. Find the slope:
The formula for slope is the change in y/ over the change in x. Or you can say rise/run.
In other words you can take any of those 2 dots, first count them to the other dot, which is -2, then count horizontally, which is 5, so the slope is -2/5
Another way:
Another way is to take any two points, like (-10, -2), and (-5, -4).
Then we can do -4 -(-2)/-5 -(-10), which is -2/5.
So the equation we have so far is y = -2/5x + b
2.Find the y intercept
Based on the graph, the y intercept is -6, so we get
y = -2/5x - 6
