Which ordered pair is a solution of the equation? x+7y=17

answer choices

a. only (10,1)
b. only (-4,3)
c. both (10,1) and (-4,3)

C. Both (10,1) and (-4,3)

Step-by-step explanation:

The equation is x + 7y = 17

Option A: x = 10, y = 1

Now, putting the value in the equation,

L.H.S.,

x + 7y

= 10 + 7*1

= 10 + 7

= 17

Therefore, L.H.S. = R.H.S.

The equation is correct.

Option B: x = -4, y = 3

Now, putting the value in the equation,

L.H.S.,

x + 7y

= -4 + 7*3

= -4 + 21

= 17

Therefore, L.H.S. = R.H.S.

The equation is also correct with this value.

As the option "A" and Option "B" shows the correct value, the answer is both A and B.

C.) Both the answers are true

Step-by-step explanation:

Simply plug it in

(10, 1) = 10 + 7(1) = 17

10 + 7 = 17

17 = 17

So A.) is true, but let's check B.)

-4 + 7(3) = 17

-4 + 21 = 17

17 = 17

B.) is also true

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
