Please help me with this -2 - (-0.7)

Mathematics
1 answer:
Amanda [17]3 years ago
8 0

Anytime you subtract a negative number, it changes it to adding a positive number.

-2 + 0.7

Since we are adding, we will have an arrow going to the right

-2 + 0.7 = -1.3

Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3

Best of Luck!

What is the radius of a circle whose equation is x^2+y^2-10x+6y + 18=0
rjkz [21]

Answer:

Explanation:

We must write this equation in the form

(

x

−

a

)

2

+

(

y

−

b

)

2

=

r

2

Where

(

a

,

b

)

are the co ordinates of the center of the circle and the radius is

r

.

So the equation is

x

2

+

y

2

−

10

x

+

6

y

+

18

=

0

Complete the squares so add 25 on both sides of the equation

x

2

+

y

2

−

10

x

+

25

+

6

y

+

18

=

0

+

25

=

(

x

−

5

)

2

+

y

2

+

6

y

+

18

=

0

+

25

Now add 9 on both sides

(

x

−

5

)

2

+

y

2

+

6

y

+

18

+

9

=

0

+

25

+

9

=

(

x

−

5

)

2

+

(

y

+

3

)

2

+

18

=

0

+

25

+

9

This becomes

(

x

−

5

)

2

+

(

y

+

3

)

2

=

16

So we can see that the centre is

(

5

,

−

3

)

and the radius is

√

16

or 4

10. 4:5....added = 9
     4/9 (1800) = 7200/9 = 800 (red)
     5/9 (1800) = 9000/9 = 1000 (green)
     there were (1000 - 800) = 200 less red ones then green ones.

11. 7/4 = 21/r
      cross multiply
      (7)(r) = (4)(21)
      7r = 84
       r = 84/7
       r = 12....Rod has 12 stickers

12. 14/4 = 3.5 eggs per cup
      for 16 cups...16 * 3.5 = 56 eggs
