Answer:
10
Step-by-step explanation:
if you take 8 and divide it by 4 you get 2 meaning that each fifth is 2 pounds. if there are 5/5 that means there are 10 pounds
The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa"
Answer:
Part 1:
Domain= {2,3,8,9}
Range = {7,9,14}
Part 2: Yes it is not a function
Step-by-step explanation:
Domain is the first number
Range is the second.
Domain= {2,3,8,9}
Range = {7,9,14} ( Notice that 14 is noted twice so just put it as once and this is not part of the answer)
Function: Is any of the domain numbers the same: Answer Yes it's a function.
Check the slope between the moving points
<span>slope between (–6, –1) & (–3, 2) = 1 </span>
<span>slope between (-3, 2) & (–1, 4) = 1 </span>
<span>slope between (-1, 4) & (2, 7) = 1 </span>
<span>the points are collinear and make an angle of 45 degrees with the x-axis </span>
<span>we can have an equation of a line passing through (-6,-1) and slope 1 as </span>
<span>(y + 1) = 1(x + 6) </span>
<span>y = x + 5 is your linear model mostly</span>
Answer:
0.675 m/s
Step-by-step explanation:
Let height of shadow= y,CD=x
Height of man=2 m
Speed of man= 

Therefore, 


Differentiate w.r.t t



When the man is 4 m from the building
Then, we have x=12-4=8 m

Substitute the values in above equation then, we get


Substitute the values then we get

Hence, the length of his shadow on the building decreasing at the rate 0.675 m/s.
