Answer:
y-4= -1/2(x-4)
Step-by-step explanation:
First you have to find the slope to write it in point slope
to do this you find change in Y over change in X
From -4 to 4 is postivite 8 and from 8 to 4 its -4
Now you do -4 divided by 8 and get -0.5 or -1/2 for slope now pick one of the points and put it in the formula y-y1=m(x-x1)
2/3 / 8/7 flip the second fraction and multiply straight across
2/3 x 7/8 2 x 7 = 14
3 x 8 = 24 so you have 14/24 if you need to simplify, since both numerator and denominator are even so divide by 2. Which gives you 7/12
Hope this helps you :)
Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y
Answer:
w=15
Step-by-step explanation:
4w+13×5 = 25×5
4w =125-65
4w =60
w=15
Subtract 8 from both sides
So you end up with x = -23
