y+16= -8
Another Question heheh

Answers

Answer:

y = -24

(mark me brainliest)

y=-24
To solve this you need to get y by itself so you have to move 16 to the other side. To do this you are doing to do the opposite of what it says so since on that side it’s addition you are going to subtract. Subtract 16 from 16 which cancels it out, then subtract 16 from -8 to get -24. Now you have y=-24

For what value of b, would the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions?

b = ____

Answers

B=23
It may even be wrong

When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.

When does a system of linear equation have no solution?

When both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.

If they are coincident, then there will have infinite solution since in that case, they will have infinite points in common.

Thus, if two lines are not in any of above case, they intersect at single point and in that case, the considered system of equation has unique single solution.

The equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.

When b = 23 ,

3/4(12x−9)+b/4=5−3(2−3x)

When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.

This is a simple graph, but I want to know if I’m right. If the line goes through the origin does that automatically mean it’s positive?
And when it doesn’t go through the origin does that mean it’s automatically negative?
THANK YOU.!

Answers

Answer: This is a negative graph and it is proportional because it goes through the origin.

Step-by-step explanation:

Just beacause it goes through the origin does not mean it will be positive nor negative, if the line goes from the top left of the grid slanted down, it is negative. If the line goes from the top right of the graph slanted down, it is positive. It is proportional because it is a straight line that goes through the origin.

Answer:Under↓↓↓

Step-by-step explanation:

Ok so in this case it's a negative slope, because the line is going from left to right.

If the line was going form right to left then It would be a positive slope.
