Answer:

m = -1 (answer A)

Step-by-step explanation:

We need the slope of the line segment connecting (-3, 5) and (5, -3). As you know, slope = rise / run. Here the rise (change in y) as we go from (-3, 5) to (5, -3) is -8 and the run is 8. Thus, the slope is m = -8/8 = 1 (answer A).

Y varies directly as x, y = 15 when x = 5. Find y when x= 6

Alona [7]

Answer:

Step-by-step explanation:

y=k×x

15=k×5

=>k=15/5=3

when x=6,

y=3×6

=18

4. When finding the intersection of two lines from both Algebra I and Geometry, you first "set the linear

Masteriza [31]

Answer:

The intersection point is (-4,-19)

Explanation:

The two given equations are:

y = 5x + 1

y = 2x - 11

To find the intersection point, we will start by equating the two given equations and solving for x

This is done as follows:

5x + 1 = 2x - 11

5x - 2x = -11 - 1

3x = - 12

x = -4

Then, we will use the x and substitute in any of the equations to get the value of y

Using the first equation:

y = 5x + 1 = 5(-4) + 1 = -19

Check using the second equation:

y = 2x - 11 = 2(-4) - 11 = -19 ................? checked

Therefore:

The intersection point between the two given equations is (-4,-19)

Hope this helps :)

A chemical plant has an emergency alarm system. When an emergency situation exists, the alarm sounds with probability 0.95. When

Katen [24]

Answer:

the probability that a real emergency situation exists is 0.16 (16%)

Step-by-step explanation:

defining the event A= the alarm sounds ,we have

P(A)= probability that an emergency situation exists * probability that the alarm sounds given that an emergency situation exists + probability that a emergency situation does not exist * probability that the alarm sounds given that an emergency situation does not exist = 0.004* 0.95+ 0.996 * 0.02 = 0.02372

then if we use the theorem of Bayes for conditional probability and define the event E= a emergency situation exists , then

P(E/A)= P(E∩A)/P(A)= 0.004* 0.95/0.02372 =0.16 (16%)

where

P(E∩A)= probability that an emergency situation exists and the alarm sounds

P(E/A) = probability that an emergency situation exists given that the alarm has sounded
