The range is all of the possible outputs when considering a function. So, when you plug in 0, you get -1, when you plug in 1, you get -1/2, and when you plug in 2, you get 1. So, the range is {-1, 1}. Hope this makes sense!

More help pls! 3 and 4

Leya [2.2K]

Answer:

3. One Solution. (0,4). (they have different slopes and y-intercepts)

The solution can be found using elimination method:

Add the equations together

y = -x + 4

y = x - 4

2y = 0

y = 0

Solve for x

0 = x - 4

x = 4

(4, 0)

4. No solution

x + y = -2 and 3 which is not possible

The two lines would be parallel

A lawyer drives from her home, located 2 miles east and 3 miles north of the town courthouse, to her office, located 5 miles

LekaFEV [45]

Let the town courthouse be the origin of coordinate plane, the positive direction of x-axis is west and negative direction is east, the positive direction of y-axis is north and negative direction is south. Then a lawyer home has coordinates (-2,3) and lawyer office has coordinates (5, -21).

Use the distance formula $d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$ to get the distance between lawyer's home and office:

 $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}=\sqrt{(-2-5)^2+(3-(-21))^2}=$
$=\sqrt{7^2+24^2} = \sqrt{49+576} = \sqrt{625} =25$ .
Answer: 25 miles.

Helpppp 2x-1>5 and 3x-5<19

maria [59]

Answer:

3 < x < 8

Step-by-step explanation:

Solve each part separately

2x - 1 > 5 ( add 1 to both sides )

2x > 6 ( divide both sides by 2 )

x > 3 , that is

3 < x

and

3x - 5 < 19 ( add 5 to both sides )

3x < 24 ( divide both sides by 3 )

x < 8

Then putting the two together

3 < x < 8
