A truck is said to get 18 miles per gallon on a highway, but this value can fluctuate,
Ratling [72]

Answer: 14 miles ≤ D ≤ 22 miles.

Step-by-step explanation:

The mean distance traveled per gallon, is 18 miles.

But this can fluctuate, at most, by 4 miles.

Because we have here the "at most", we know that we should use the ≤, ≥ symbols.

Then, if the mean is 18mi, the range of possible distances traveled per gallon is:

(18 miles - 4 miles) ≤ D ≤ (18 miles + 4 miles)

Where D is the distance.

14 miles ≤ D ≤ 22 miles.

So the truck can get between 14 miles and 22 miles per gallon on the highway.

Match each system of equations to its graph. y = 2x + 1 y = x + 2 y = 3x y = x + 3 y = 2x − 2 y = x − 2 y = 2x + 3 y = x + 5 y =
GalinKa [24]

The matchup are:

  • (1st picture): y=2x+3 and y=x+5
  • (2nd picture): y=4x+2 and y =3x+2
  • (3rd picture): y=2x+1 and y =x+2
  • (4th picture): 3x and x+3

<h3>What does the graph of an equation shows?</h3>

The graph of the linear equation is known to be one that often brings or  set the  points that can be found on the coordinate plane and it is one that shows all the solutions to the equation.

Note that when  all variables stands for real numbers, a person can be able to use graph to show the equation and this is often done through plotting the points to show a pattern and then link up the points to have all the points.

From the above, the pictures that have all the points as shown on the graph are:

  • (1st picture): y=2x+3 and y=x+5
  • (2nd picture): y=4x+2 and y =3x+2
  • (3rd picture): y=2x+1 and y =x+2
  • (4th picture): 3x and x+3

How many radians are in one degree, accurate to three decimal places?
qaws [65]
Now, if you recall, there are 180° in π radians, now, so how many radians in 1°?

\bf \begin{array}{ccll}&#10;de grees&radians\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;180&\pi \\&#10;1&r&#10;\end{array}\implies \cfrac{180}{1}=\cfrac{\pi }{r}\implies r=\cfrac{1\cdot \pi }{180}
