Answer:
Your answer would be B. A metal railing rusting in damp weather because anything that contains any sort of rust whats so ever is always considered a chemical change.
Answer:
D
Step-by-step explanation:
We equate both the y's and solve for x algebraically:
Now taking the value x= 14 and putting it in the 1st equation would give us y:
Hence the solution is (14,8), answer is D
The answer would be 8 2/3
Answer:
The correct answer is A. Both samples are dependent samples.
Step-by-step explanation:
Both samples are dependent samples, since to verify the effects of one, it is necessary to compare it with the effects and characteristics of the other.
Thus, in the case, it is intended to check the effects of caffeine on taste by using a regular soda sample first, and then comparing it with a decaffeinated soda sample. Therefore, the effects of one sample will be checked and compared with the other sample, so that there is a dependency relationship between the two, since neither could prove the hypothesis on its own.
Let y=0 to find the x-intercept(s).
0=−3x−4
Add 4 to both sides.
4=−3x
Divide both sides by -3
-4/3 =x (fraction)
Switch sides.
x=−4/3 (fraction)
Let x=0 to find the y-intercept(s).
y=−3×0−4
Simplify
y=−4
