angle JAB,

dihedral angle is the angle between two intersecting planes. So, the angle with the same measure of the dihedral angle formed by plane DAJ and plane ABC is angle JAB

Which of the following is not a solution to the system of linear equations below? 5y=3x+15 6x=10y-30 A. (5, 6) B. (–15, 12) C. (

Alecsey [184]

Option B is not a solution.

5y=3x+15
5(12)=3(-15)+15
60=-45+15
60≠-30

Hope I didn't mess up for your sake!

PLEASE HELP ASAP!!!!

Answer:

y = -2x + 8

Step-by-step explanation:

The point slope form of an equation is written as

y = mx + c ...............(i)

Where m is the slope and c is the constant

Now we Know that the equation is

y + 2 = -2(x-5)

and the given points are

m= -2

x = 5

and y= -2

Putting these values in equation (i) to find the value of c

y = mx + c

it becomes

-2 = -2(5) + c

-2 = -10 + c

Adding 10 on both sides

-2 + 10 = -10 + 10 + c

8 = c

or c=8

Now we have the values of m and c

where m= -2 and c = 8

Point slope form of an equation is

y = mx + c

putting the values of m and c to get equation in slope intercept form is

y = (-2)x + 8

y = -2x + 8

Other method:

The given point slope form is

y + 2 = -2(x-5)

We have to change it in y= mx + c form

so solving it

y + 2 = -2x + 10

Subtracting 2 from both sides

y + 2 -2 = -2x + 10 -2

y = -2x + 8

which is same is

y=mx + c

so the required equation is

y = -2x + 8

Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey

shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)

as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8

the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6

Write out the sample space for the given experiment. Use the following letters to indicate each choice: M for mushrooms, A for a

MrMuchimi

Answer: {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

Step-by-step explanation:

Sample space is a set that contains all the possible outcomes for an event.

For salad:

Choices for extra toppings (mushrooms, olives) =2

Choices for meats (bacon, eggs) =2

Choices for dressings (vinaigrette, honey mustard.)= 2

By Fundamental counting principal .

The number of different salads can be made= (Choices for extra toppings) x (Choices for meats ) x (Choices for dressings)

= 2 x 2 x 2 = 8

All the possible outcomes = (MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)

Required Sample space would be : {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}
