Answer:

x=5, y=4. (5, 4).

Step-by-step explanation:

2x-3y=-2

4x+y=24

------------------

-2(2x-3y)=-2(-2)

4x+y=24

----------------------

-4x+6y=4

4x+y=24

--------------

7y=28

y=28/7

y=4

4x+4=24

4x=24-4

4x=20

x=20/4

x=5

Perpendicular lines intersect to form four right angles. never always sometimes
natima [27]

Answer:

Always

Step-by-step explanation:

The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.

The 12th term and the sim of 1+3+5+7+.....
zzz [600]

To find this, first find the factor or rate of which the numbers are moving. To do so do as follows.

subtract 1 from 3

3-1=2

So each number is having 2 added to it.

Now add two to 7 and the numbers afterwards till you get the 12th term

7+2=9

1+3+5+7+9

9+2=11

1+3+5+7+9+11

11+2=13

1+3+5+7+9+11+13

13+2=15

1+3+5+7+9+11+13+15

15+2=17

1+3+5+7+9+11+13+15+17

17+2=19

1+3+5+7+9+11+13+15+17+19

19+2=21

1+3+5+7+9+11+13+15+17+19+21

21+2=23

1+3+5+7+9+11+13+15+17+19+21+23

So 23 is the 12th term

How do you solve 21/4=1/2x+3x and whats the answer?
MissTica
Hi there!

To solve is pretty easy. First, simplify.

21/4=(1/2x+3x) -> Combine Like Terms
21/4=7/2x
FLIP
7/2x=21/4

Multiply both sides by 2/7.
(2/7)*(7/2x)=(2/7)*(21/4)
x = 2/3

Hope this helps!
