The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the

time (in hours) after the snowstorm beings.
A. Graph the function and identify its domain and range. Write your answers as inequalities.

The domain is ___ and the range is ___

B. Interpret the slope and the d -intercept of the graph.

The d -intercept means that there were __ inches of snow on the ground at the start of the storm and the slope means that ___ inches of snow falls every hour during the storm.​

Answer:

I dont know the domain and range. But the d-intercept means that there were 6 inches of snow and the slope means that 1/2 inches snow falls. To graph it you would go on 0 and up 6 and then go to 9 on the x and go to 10.5 which would be in the middle of 10 and 11.

Are the ratios 5:3 and 15:12 equivalent? Justify your answer?
Romashka [77]
No, if you do something to one side you do to the other. So 3 times 4 is 12 and 5 times 4 is not 15. I hope that makes sense

Class a has x students and class b has y students. the average of class a is 85 and class b is 90. when the scores of class a an
Usimov [2.4K]
The total scores of the x students from class A can be calculated by multiplying x and the average which is equal to 85. That is 85x.

In similar manner, we are able to find for the total scores of the students from Class B. That would be, 90y.

Combining the scores, the new average then becomes 88. This is equal to,

                                 (85x + 90y) / (x + y ) = 88

Cross-multiplying,
                            85x + 90y = 88x + 88y

Combine all the x's and y's in each side of the equation.

                        85x - 88x = 88y - 90y

Combining terms,
                              -3x = -2y

The ratio is obtained through the step below,
                         -3x/-3y = -2y/-3y

                            x/y = 2/3

Thus, the ratio is 2/3.

Write a equation that is parallel to 5x-y=4
ozzi
Let's have this equation equal y first. All we have to do is add y to both sides and subtract 4 from both sides.
5x-4=y
Now, to get a parallel line, the y intercept has to change. The y intercept (the -4 in the equation) can be an infinite amount of number but -4.
Let's choose 6. We would have 5x+6=y or you could put it in the way the other equation was, 5x-y=-6.
