Answer:
w = -8
Step-by-step explanation:
step 1:(20 - 9w) - 4 • (15 - w) = 0
step 2: -5w - 40 = -5 • (w + 8)
step 3: -5 • (w + 8) = 0
step 4: Subtract 8 from both sides of the equation :
w = -8
The answer is B
89+12+9=110
100(.25)=27.5
110-27.5=82.5
Answer:
Base 12m Height 5m
Step-by-step explanation:
Area of a triangle formula A=1/2bh
30=1/2(x)(x-7)
2*30 = 1/2(x)(x-7)*2
60 = x^2 -7x
60 - x^2 + 7x = 0
-60 + x^2 -7x = 0
x^2 -7x -60 =0
x^2 + 5x -12x -60 = 0
x(x+5)-12x-60=0
x(x+5)-12(x+5)=0
(x+5)*(x-12)=0
x+5=0
x-12=0
x=-5
x-12=0
x=12
The final answer is: x= 12,5
get rid of the -5 because -5 does not make sense at a height so turn it into 5
Base: 12m
Height 5m
This would be 2c^3 Answer
Answer:
Following are the solution to this question:
Step-by-step explanation:
For this set, the correlation coefficient is = -0.015.
It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.
It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.
