Answer:
-3072
Step-by-step explanation:
Five hundred -&- seventy thousand -&- twenty dollars
Length:width
6 inches: 1 inch
30 inches: 5 inches
Since the ratio for length is multiplied by 5, you would do the same for width.
Answer:
The Predictor variable is the amount of precipitation received while the Response variable is the crop harvest.
Step-by-step explanation:
The Response variable in an experiment is the factor being measured or studied. They are also known as the dependent variables. Predictor variables are those values that explain the changes in the Response variable. They are also known as the independent variables.
In the question above, the amount of precipitation provides an explanation for the harvest of his crops. Therefore, the amount of precipitation can be rightly described as the predictor or independent variable, while the harvest of his crops is described as the response or dependent variable.
For any point (x, y), that appears in one function, the point (y, x) must appear in the other function.
<span>For any point (x, y), that DOESN'T appear in one function, the point (y, x) must NOT appear in the other function. </span>
<span>So if you find any point that DOESN'T meet the above rules, you can prove that the functions are NOT inverses of each other. </span>
<span>But if you want to prove that they ARE inverses of each other, you have to check ALL points in the functions, and there are infinity of them, so that's not practical. Instead, you can write f(x) like this: </span>
<span>y = 3x - 5 </span>
<span>Now solve for x: </span>
<span>y + 5 = 3x </span>
<span>x = (y + 5) / 3 </span>
<span>Now swap x and y: </span>
<span>y = (x + 5) / 3 </span>
<span>This is the same as g(x). Therefore the functions are inverses of each other.</span>
