2-(-8)=10

When subtracting a negative number, you will actually add. You can double check this by counting on the number line. Make sure you count by 2.

HELPPPPPP SOLVE FOR X
Diano4ka-milaya [45]

Answer:

x = 6

Step-by-step explanation:

These are supplementary angles.

This means that the angles add up to 180 degrees.

The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.

6y = 90

y = 15

Now that we have found y we can solve for x.

Plug in the y to the 5x + 4y

5x + 4(15)

5x + 60

We can set this equal to 90 again

5x + 60 = 90

5x = 30

x = 6

Therefore x is equal to 6.

The slope of a line is –2 and its y-intercept is (0, 3). What is the equation of the line that is parallel to the first line and
Doss [256]

Answer:

The answer is A) 2x + y  = 6

Step-by-step explanation:

Since the first line has a slope of -2, we know that the second does as well. We know this because parallel lines have the same slope. Now we can use that slope along with the point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 2 = -2(x - 2)

y - 2 = -2x + 4

y = -2x + 6

In this case, to find an equation that is similar, we could put it into standard for.

y = -2x + 6

2x + y = 6

This is answer A

An experiment consists of choosing objects without regards to order. Determine the size of the sample space when you choose the
sdas [7]

Answer:

a

    n=  75, 582

b

  n=    2300

c

  n =   253

Step-by-step explanation:

     Generally the size of the sample sample space is  mathematically represented as

           n  =   \left N } \atop {}} \right.  C_r

Where   N is the total number of objects available and  r is the  number of objects to be selected

    So  for  a,  where N = 19  and r = 8  

         n  =   \left 19 } \atop {}} \right.  C_8 =  \frac{19 !}{(19 - 8 )! 8!}

                           =     \frac{19 *18 *17 *16 *15 *14 *13 *12 *11! }{11 ! \ 8!}

                           n=  75, 582

    For  b  Where  N  = 25 and  r  =  3

           n  =   \left 25 } \atop {}} \right.  C_3 =  \frac{25 !}{(19 - 3 )! 3!}

                             =     \frac{25 *24 *23 *22 !  }{22 ! \ 3!}

                             n=    2300

   For  c  Where  N  = 23 and  r  =  2

            n  =   \left 23 } \atop {}} \right.  C_2 =  \frac{23 !}{(23 - 2 )! 2!}

                              =     \frac{23 *22 *21!  }{21 ! \ 3!}

                              n =   253

The points (2, 3) and (6, 11) lie on a line. What is the slope of this line?
AveGali [126]

Answer:

8/4

Step-by-step explanation:

to do slope is y2 - y1 over x2 - x1, so it would be 11 - 3 for 8, then 6 - 2, leaving 8/4.
