Question

Which ordered pair in the form (a, b) is a solution of this equation?

7a – 5b = 28


A.
(0, 4)

B.
(–2, –3)

C.
(–3, –2)

D.
(4, 0)

Answer 1

tell me your answer !

Answer 2

maybe ether a or d

Answer 3

The answer is D

Answer 4

k

Answer 5

A is not possible because if a = 0 then the whole part (7a) becomes zero
According to the equation 7a - 5b = 28 if 7a becomes zero 28 = -5b then b should have a negative value. But in the answer A u have a positive value for b with the zero for a so that's wrong.
D is correct because when u substitute it to the equation
7*4 - (5*0) = 28
28 - 0 =28
Then u get the answer right!

Answer 6

For which points is the sum of their x- and y-coordinates greater than 4 [for example, (5, 2) since 5 + 2 = 7, or (–3, 9) since –3 + 9 = 6]?

A.
E, X

B.
Z, J

C.
X, L

D.
D, L

answers r b, d, or c

Answer 12

it would be better if you made a new post for your question :)

Answer 13

ok

Answer 14

C - the x co-ordinate = -4
the y co-ordinate = +5
That sums up to +1 (5-4 = 1)

D - the x co- ordinate = -9
The y co-ordinate = -9
that sums up to 0

Answer 15

E - the x co-ordinate = +5
the y co-ordinate = 0
that sums up to +5 which is greater than 4 so that's in

Answer 16

j- the x co-ordinate = -9
the y co=ordinate = 0
Sums up to -9

Answer 17

L - the x- co-ordinate = +9
the y co=ordinate = -9
sums upto 0

Answer 18

p - the x co-ordinate = 0
the y co-ordinate = -9
sums up to -9

Answer 19

x - the x co-ordinate = 0
the y co-ordinate = +5
that sums up to +5 which is greater than 4 so an answer

Answer 20

Z - the x co-ordinate = 10
the y co-ordinate = 10
sums up to 20 so that can be included in to the answer too.

Answer 21

But in the given answers Z is paired up with j which is not greater than 4 so there one answers is wrong therefore we can't take that answer as the correct one :)

Answer 22

Oops I didn't see the new question cumn. Sorry this is the explanation for the 2nd question u posted here

Answer 23

its ok

Answer 24

can u open up a new question for that. I'll check that :)

Answer 25

yeah
