Let fat be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 121 + 1.42x?
emmasim [6.3K]

Using <u>linear function concepts</u>, it is found that the correct option is:

The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which represents by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • The explanatory variable fat is the input.
  • The response variable calories is the output.

The equation is:

y = 121 + 1.42x

  • The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.
  • The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.

Thus, the correct option is:

The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

Step-by-step explanation:

-x/6-1=-13

add 1 to both sides

-x/6=-12

multiply 6*-12

-72

x=-72 because -72/6=-12

Which sets of points represent one-to-one functions?
madreJ [45]
<h3>Two Answers: </h3><h3>Function h (third choice)</h3><h3>Function k (sixth choice, or last choice)</h3>

==========================================================

Explanation:

A function is only possible if the x values do not repeat. A relation is considered one-to-one only if the y values do not repeat. We combine the two ideas. If we want a one-to-one function, then neither x nor y can repeat.

  • Function f has y = 8 repeating, so it is not one-to-one
  • Function g is a similar story but y = 4 repeats.
  • Function h has all unique x values, and all unique y values. This function is one-to-one.
  • Function i has y = 3 repeating, so it is not one-to-one.
  • Function j has y = 16 show up more than once, so it is not one-to-one.
  • Function k has all unique x values, and all unique y values. This function is one-to-one.

Note: if we had two points like (1,2) and (3,1), then it is still one-to-one (even though the digit 1 shows up twice). This is because the set of x values {1,3} is unique, and so is the set of y values {2,1}. We look at each set separately and not combine the two sets.
