Which graph represents a linear function?
pshichka [43]

Answer:

y + 2x = 10 (third option)

Step-by-step explanation:

We can see that every time x increases by one, y increases by -2, meaning that the slope is -2.

We also know that the y-intercept is 10 because that is the value of y when x is equal to 0.

Now, we can create the equation using the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept).

y = -2x + 10

If you look at the third option, that equation is just a rearranged form of our equation (y + 2x = 10).

This means that the third option is correct.

katrin [286]

9514 1404 393

Answer:

  1. |w -30| > 1.6
  2. (-∞, 28.4) U (31.6, ∞)

Step-by-step explanation:

1. The snack bags will be rejected if their weight differs from 30 grams by more than 1.6 grams:

  |w -30| > 1.6

__

2. This inequality resolves to two inequalities.

  w -30 > 1.6

  w > 31.6 . . . . . add 30

and

  -(w -30) > 1.6

  w -30 < -1.6 . . . multiply by -1

  w < 28.4 . . . . . add 30

The solution in interval notation is the union of the two disjoint intervals:

  (-∞, 28.4) U (31.6, ∞)

Suppose the population of a certain city is 5289 thousand. It is expected to decrease to 4530 thousand in 50 years. Find the per
Tcecarenko [31]

Answer:

14.4% decrease

Step-by-step explanation:

Here is the formula for finding the percentage of decrease:

(starting value - final value) / starting value * 100.

So for your question,

\frac{5289-4530}{5289} =.0144\\.0144 * 100 = 14.4\\/

There was a 14.4% decrease within 50 years.

In December of 2003, the average price for a gallon of regular gas in the United States was $1.50.
12345 [234]

Answer:

yes

Step-by-step explanation:

because the cost stays the same and you would multiply blank gallons of gas by 1.50 every time so it is proportional. For example: it would be $1.50 to 1 gallon, $3 to 2 gallons, $4.50 to 3 gallons and would keep going like that, adding the same amount every time
