Question three (1 point)
laila [671]

Answer:

B. (-2,-3)

Step-by-step explanation:

we know that

If a ordered pair is a solution of  a linear equation. then the ordered pair must satisfy the linear equation

In this problem we have

7x-5y=1

<u>verify each case</u>

case A) (-3,-2)

substitute the value of x and the value of y in the linear equation and then compare

7(-3)-5(-2)=1

-11=1 -----> is not true

therefore

The ordered pair case A) is not a solution

case B) (-2,-3)

substitute the value of x and the value of y in the linear equation and then compare

7(-2)-5(-3)=1

1=1 -----> is true

therefore

The ordered pair case B) is a solution

case C) (0,4)

substitute the value of x and the value of y in the linear equation and then compare

7(0)-5(4)=1

-20=1 -----> is not true

therefore

The ordered pair case C) is not a solution

case D) (4,0)

substitute the value of x and the value of y in the linear equation and then compare

7(4)-5(0)=1

28=1 -----> is not true

therefore

The ordered pair case D) is not a solution

5+ 1/7b = -2<br>whats be and explanation<br>(don't get it cause its a fraction)
oee [108]
5+(1/7)b=-2

First subtract 5 from both sides. Our goal is to isolate b.
5+(1/7)b-5= -2-5
(1/7)b= -7

Now multiply both sides by 7 because (1/7)*7= 7/7 or 1.
7* (1/7)b= -7*7
1b= -49

Final answer: b= -49
