Question

Determine which ordered pair in the form (x, y) is a solution of the given equation.

(x + 3)y = 14 (Points : 1)
(11, 1)
(3, 2)
(5, 2)
(7, 2)

Answer 1

Which pairs are solutions to the equation?

5xy + 9 = 44
(Points : 1)
(1, 7) and (4, 11)
(1, 7) and (7, 1)
(7, 1) and (2, 3)
(4, 11) and (2, 3)
this is the last Q of the test

Answer 2

so the first question:
you have 4 choices of x and y, if you substitute those into the equation, it is a solution if it makes it true, such as 2x=2, a solution to this is x=1 because then 2=2

Answer 3

ok

Answer 4

what about the second?

Answer 5

so if you start with the first one put 11 in for x and 1 in for y. does (11+3)(1) = 14? if so then that is the answer

Answer 6

do the same for the second. just now you have more numbers to try.

Answer 7

ya it does

Answer 8

for the second one. look at the first one
5xy + 9 = 44
x = 1 y = 7 and the pair
x = 4 y = 11
5(1)(7) + 9 = 44 and 5(4)(11) + 9 = 44
5*7 + 9 = 44 and 5* 44 + 9 = 44
35+9 = 44 and 220+9 = 44
then you ask do both of these make sense? if not then go to the next set of pairs

Answer 9

by first one here i mean the first ordered pairs

Answer 10

to me it kinda makes sense does it make sense to you

Answer 11

it doesnt because 220+9 =44 isnt true. 229 =44 and 229 does not equal 44. but you do get some help here though. after looking at those first pairs you found that x=1 and y = 7 works to have 44=44. so if you try others with that ordered pair you already know one of those works.
looking at the second set
x=1 y=7 and x=7 y=1

Answer 12

man!donts you wish math and algebra and all kinds of math wasnt invented so hard

Answer 13

haha i like math, i wish english wasnt here. i mean i like speaking and all but get rid of the nouns and verbs. english isnt my thing

Answer 14

math isnt my thing AT ALL

Answer 15

ok my test thing says i only have a minute to finsh or it will be turned in and i have tow Qs left but im not done ugh

Answer 16

two**

Answer 17

do you know the answer to the 2nd question you asked

Answer 18

no

Answer 19

i have 30 seconds left

Answer 20

okay so you know x=1 and y=7 works and since it is multiplication y=7 and x=1 works as well

Answer 21

so b

Answer 22

my math grade is low thats why i want some good correct answers

Answer 23

and the first one was the first option

Answer 24

ok thank you so much for helping me

Answer 25

no problem
