Answer: Third Option
yes; k = 4 and y = 4x
Step-by-step explanation:
Observe in the values of x and y given that when x decreases the variable-y also decreases.
Then the variation is direct.
Then, if between any two points of the function, the rate of variation k remains the same then the variation is constant.
We can test whether these conditions are met by using the given points.
(-2, -8) and (-4, -16)
The rate of variation k for these points is:
Now we calculate the variation rate for the points
(-4, -16) and (-6, -24)
The rate of variation is constant and equal to 4.
Then the answer is yes; k = 4 and y = 4x

Answer:
the number of time spend in reading is 31.3 minutes
Step-by-step explanation:
The computation of the number of time spend in reading is as follows:
= 9.75 pages in science book × 1.2 minutes + 24.5 pages in english class × 0.8 minutes
= 11.7 minutes + 19.6 minutes
= 31.3 minutes
Hence, the number of time spend in reading is 31.3 minutes
The same is relevant and considered
