Answer:
x = 13
Step-by-step explanation:
call the missing number x
8 - x = - 5 Subtract 8 from both sides
8-8 - x = -5-8 Combine
-x = - 13 Multiply by -1
x = 13
Answer:
B) consistent, dependent
Step-by-step explanation:
The given system is
45x - 30y = -90
-12x + 8y = 24
Let us make y the subject in both equations to get:
Top equation
Bottom equation
We can see that both equations are identically the same.
There is going to be infinitely many solutions.
We say the system is consistent and dependent.
The correct choice is B
I believe the answer is 22/12

When a line is parallel to another, it means they have the same slope. The equation of the line is y=my+b where m=slope. Our original slope is -2, and we need this line to pass through the points (2,2). So we simply plug the information in the point slope formula which says....
y-y1=m(x-x1) where m=-2, x1=2, and y1=2
Y-2=-2(x-2)... I am going to destitute the -2 into the x and 2.
Y-2=-2x+2.... now I am going to isolate the y to put it in y=my+b form by adding 2 to both sides and we see that it cancels on the left.
Y=-2x+4 I believe should be your answer but is not there. Further it should be noted that there must be a typo either in the answer choices, or in the wording of the question because this equation does not pass through (2,2)
