Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3
Answer:
5.3x − 8.14 + 3.6x + 9.8
group the numbers on one side and the x's on the other
5.3x + 3.6x - 8.14 + 9.8
solve
8.9x + 1.66
Brainliest pls ;)
3 because you add each exponent in a trinomial.
The histogram shows the heights in meters of trees in a certain section of a park.
How many trees are less than 20 meters tall?
Answer: From the given histogram, we clearly see:
There is 1 tree with height less than 8 meters
There are 1 + 2 = 3 trees with height less than 12 meters
There are 3 + 2 = 5 trees with height less than 16 meters
There are 5 + 4 =9 trees with height less than 20 meters.
Therefore, the correct option is B. 9
Answer:
a
Step-by-step explanation:
8 (x/4 -6) >= 4
(x/4 - 6) >= 4/8
(x/4) >= 0.5 +6
x >= 6.5 x 4
x>= 26
