y = -2x + 3

in the equation y = mx + b, the m represents the slope and b represents the y-intercept

remember that slope is rise over run:

   starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).

   add a negative sign to show the negative downward slope, and the m in the equation would be -2

the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept

just plug all that into y = mx + b

m, the slope, is -2 and b, the y- intercept, is 3.

y = -2x + 3 is your answer

Answer:

1.  4   2. 2   3. Does not exist   4. Does not exist   5. 3

Step-by-step explanation:

1. This is the limit as x approaches 2 from the left.  That means that x "sneaks up" on 2, but from the left (ironically moving right). As  x  does that, the graph rises, heading for 4 (even though the point is "empty").  The limit is 4.  See attached image 1

2. Let  x  sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2.  The limit is 2.  See image 2.

3. This limit (two-sided) does not exist because the one-sided limits had different values.

4. This limit does not exist, either.  The limit as x approaches 0 from the left is 4.  The limit as x approaches 0 from the right is 0.  These are different, so the two-sided limit is not defined.

5. g(2) = 3, where the solid dot is.  It's the value of the function at x=2.

state the angle pair relationship then find the value of x

Answers

Answer:

x = 11

Step-by-step explanation:

The given angles are corresponding angles and are congruent, then

12x - 9 = 10x + 13 ( subtract 10x from both sides )

2x - 9 = 13 ( add 9 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11

According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?

Answers

Answer: 24%

Step-by-step explanation:

First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.

This is:

= 5/25 + 1/25

= 6/25

Then convert this to a percentage:

= 6/25 * 100

= 24%

What is the solution to the system of equation of 2x+3y=6 and x-3y=9

Answers

Answer:

x = 5

y = -4/3

Step-by-step explanation:

Solve by elimination by adding the two equations together:

2x + 3y = 6

x - 3y = 9

3y and -3y will cancel out. Then, solve for x:

3x = 15

x = 5

Plug in 5 as x into one of the equations, then solve for x:

x - 3y = 9

5 - 3y = 9

-3y = 4

y = -4/3

So, the answer is x = 5 and y = -4/3

A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?

Answers

Answer:

$70 is the regular price of the shirt.

Step-by-step explanation:

One way in which to find the regular price here is to write the equation

0.60s = $42.  A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.

If 0.60s = $42, then the regular price of the shirt is

s = ($42)/0.60 = $70

Answer:

$70.00

The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what speeds are the two trains traveling?

Answers

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58

52=x

To prove that x=52 you can input 52 as x in the equation

Answers

Answer:

(9x, 9y) dilation

(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.
