Question

Choose the ordered pair (x,y) that is a solution of the equation.

-8x + 5y = 96

Answer 1

solve for x first,equate y=0 and solve

Answer 2

how

Answer 3

let x=0 first and then solve.

Answer 4

i need help

Answer 5

do you have a list of ordered pairs, or are you only supposed to find one?

Answer 6

A.

(-3,11)




B.
(1,-19)




C.
(3,19)




D.
(-2,16)

Answer 7

i thought so
since you have a list, you have to replace \(x\) and \(y\) by the numbers in each ordered pair \((x,y)\) and see if the equality is true or not

Answer 8

what do you mean

Answer 9

pick one of the points and i will show you
choose one

Answer 10

c

Answer 11

(3,19)
equation is \(-8x + 5y = 96 \) you replace \(x\) by \(3\) and\(y\) by \(19\) and you get
\[-8\times 3+5\times 19=96\] which is either true or false, so we have to compute

Answer 12

\[-8\times 3+5\times 19=96\]
\[-24+95=96\]? no it does not
pick another one

Answer 13

a

Answer 14

(-3,11)
\[-3\times (-3)+5\times 11=96?\]
\[9+55=96?\] i don't think so
pick another one

Answer 15

d

Answer 16

If it was choice d, then...

-8x + 5y = 96

-8(-2) + 5(16) = 96

16 + 80 = 96

96 = 96

which is true

So (-2,16) does lie on the line, which makes it a solution

Answer 17

thanks
