Answer:

The domain of the graph is {-3, -1, 1, 4}. The range of the graph is {-4, -1, 1, 4}

The domain of the set of ordered pairs is {-4, -3, 1}. The range of the set of ordered pairs is {1, 3, 4}

at 1:30 in the afternoon an old freight train and a new dart express train pull out of the new garland station going in opposite

nydimaria [60]

Solution: The speed of old freight train is 0.5 miles per minute and the speed of new dart express train is 1.5 miles per minute.

Explanation:

Let the speed of old freight train is x miles per minute and the speed of new dart express train is y miles per minute.

It is given that the speed of the dart express train is three times faster than the freight train. So, it can be written as,

$3x=y$ ....(1)

The trains are moving towards the opposite directions, therefore the distance between them is increased at the speed of $(x+y)$ miles per minute.

$Distance=Speed\times Time$

The distance between both train in 15 minutes is represented by $15(x+y)$ .

According to the given information the distance between trains is 30 miles in 15 minutes.

$15(x+y)=30$

$x+y=2$

Use equation (1) and put $y=3x$

$x+3x=2$

$4x=2$

$x=0.5$

Put this value in equation (1), to find the value of y.

$y=3(0.5)$

$y=1.5$

Therefore, the The speed of old freight train is 0.5 miles per minute and the speed of new dart express train is 1.5 miles per minute.

PLZ ANSWER THIS I CANT FIGURE OUT THE SECOND ONE

mihalych1998 [28]

Answer:

Step-by-step explanation:

The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.

Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.

Express as a trinomial.<br> (x−8)(2x+9)

Tomtit [17]

Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them

2x²+9x-16x-72
2x²-7x-72

Please help me!!!!!!!

Answer:

R'(-2, 2)
F'(2, 2)
G'(-2, -2)

Step-by-step explanation:

It can be useful to keep a list of the 90° rotation transformations.

(x, y) ⇒ (-y, x) . . . . . . 90° CCW, 270° CW

(x, y) ⇒ (-x, -y) . . . . . . 180°

(x, y) ⇒ (y, -x) . . . . . . . 270° CCW, 90° CW

1) (x, y) ⇒ (-x, -y) . . . . 180°

R(2, -2) ⇒ R'(-2, 2)

2) (x, y) ⇒ (-y, x) . . . . 90°

F(2, -2) ⇒ F'( 2, 2)

3) (x, y) ⇒ (y, -x) . . . . 270°

G(2, -2) ⇒ G'(-2, -2)
