Step-by-step explanation:
1.Get the equation in the form y = ax2 + bx + c.
2.Calculate -b / 2a. This is the x-coordinate of the vertex.
3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
I need help my self lol XD sorryyyyyyyyy88898
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.
Answer:
Step-by-step explanation:
x+1/2x=5-1/5x
combine like terms on left side
3/2x=5-1/5x
add 1/5x on both sides
17/10x=5
multiply by 10 on both sides to get rid of fraction
17x=50
divide 17 on both sides witch leaves
x=50/17
If Brainiest is earned its Greatly Appreciated
The answer is the number that 'Y' must be in order for
the equation to be true.
That number is called the 'solution' to the equation.
Here's one way to go about finding it:
You said that - 6y - 3 = 3 - 6y
Add 6y to each side: - 3 = 3
Let's stop right here.
Is there any value of 'Y' that can make -3 = 3 ?
I don't think so.
Your equation has NO SOLUTION.
There is NO NUMBER that you can write in place of 'y'
in your equation
- 6y - 3 = 3 - 6y
and have it work out to be true.
That's OK. There are lots of equations that have no solution.
