Triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side because if not you don't have a triangle.
Answer:
See possible solutions below.
Step-by-step explanation:
There are no listed statements. However, looking at the function can provide important information:
- y = -4 is a horizontal line through -4 on the y-axis
- All inputs have the same output -4 in this function
- This function has a y-intercept at (0,-4)
- This function has a slope of 0
False items about this function include:
- Vertical line
- All inputs are -4
- Has on slope or slope is undefined.
You would substitute all x's with the number 30, so the answer would be f(30)=-1 or y=-1
Answer:
Step-by-step explanation:
The equation representing the growth of the plant after x weeks is expressed as
y = 0.2x+2
Where
x represents the number of weeks.
y represents the height of the plant after x weeks in inches.
A.
The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes
y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.
B is incorrect.
C.
The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes
y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.
D is incorrect
The answer would be 6:15 since it can be divided by two and equal 3:5, i think
