Answer:

(-2,8)

Step-by-step explanation:

3x+3y = 18

2x+y = 4

Multiply the second equation by -3

-3(2x+y) = -3*4

-6x-3y = -12

Add this to the first equation

3x+3y = 18

-6x-3y = -12

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

-3x = 6

Divide each side by -3

-3x/-3 = 6/-3

x = -2

Now solve for y

2x+y = 4

2(-2) +y = 4

-4+y =4

Add 4 to each side

-4+4+y = 4+4

y =8

Answer:

(-2,8)

Step-by-step explanation:

3x + 3y = 18 (1)

2x + y = 4 (2)

(1) - 3(2)

3x + 3y = 18

-(6x + 3y = 12)

-3x = 6

x = -2

Using (2)

2(-2) + y = 4

-4 + y = 4

y = 8

prisoha [69]

Answer:

Step-by-step explanation:

1²+16²=1+256=257≠289(17²)

2²+16²=4+256=260≠17²

3²+16²=9+256=265≠17²

4²+16²=16+256=272≠17²

5²+16²=25+256=281≠17²

6²+16²=36+256=292>17²

6²+15²=36+225=261≠17²

7²+15²=49+225=274≠17²

8²+15²=64+225=289=17²

9²+14²=81+196=277≠17²

10²+14^2=100+196>289

10²+13²=100+169=269≠17²

11²+13³=121+169=290>17²

11²+12²=121+144=265≠17²

12²+12²=144+144=288≠17²

so only integer values are 8²+15²=17²

(x+4)²+(y-7)²=17²

if x+4=8

x=8-4=4

y-7=15

y=15+7=22

so q is (4,22)

if x+4=15

x=15-4=11

y-7=8

y=8+7=15

point is (11,15)

Select all the fractions that are equivalent to 30%.
choli [55]
30% is equivalent to 3/10
So any fraction that can be simplified to 3/10.
Another way to to think about it if you multiply 3/10 by any number over it self because that is equivalent to 1.
Like 3/10 * 2/2 =6/20 is also equal to 30%

Please help when there are two x's i get confused. answer #3 with an answer!
igomit [66]

Answer:

x = 1

Step-by-step explanation:

We know that the two angles must be equal to each other. So:

65x - 12 = 43x + 10

First add 12 to both sides:

65x - 12 + 12 = 43x + 10 + 12

65x = 43x + 22

Then subtract 43x from both sides:

65x - 43x = 43x - 43x + 22

22x = 22

x = 1
