If you're completing the square the answer is in the image.

expression

x^2 + 5x - 5=ax^2+bx+c

a=1, b=5, c=-5, and you can solve it that way.

Help please !!!!!!!!

Answer:

y = -4

x = 3

Step-by-step explanation:

Let's first explain when x = 0

Find where x = 0 on the graph. We are finding what the y-value would be. Trace down the y-axis along the vertical line x = 0. Where does the line intersect the y-axis when x = 0? The answer would be -4

The y-intercept is -4, and the x-value for this is 0, of course. So the correct answer for when x = 0 would be y = -4.

Next, we are told to find x when y = -2. Find where y = -2. Now, staying at y = -2, go horizontally along the x-axis at y = -2 until you reach the line. Boom! You should have connected up with the line at around x = 3. Therefore, when y = -2, x = 3

Please tell me, how do i solve percentages? And yes, i know there is more than one way. Please tell me the methods to solve all
Bumek [7]
I'll give a practice problem to help explain it a bit better.

Here, let's try to solve 45% of of 60.

First, we convert the percentage into a decimal. To turn any percentage into a decimal you move the point two spaces to the left.

That means 45% as a decimal is .45.

Next, we multiply our number, 60, by the decimal .45.

60×.45=27.

That means 45% of 60 is 27.

To sum it all up, you have to get the percentage, move the decimal point two spaces to the left, and multiply it by the number you were trying to find the percentage of.

Have a wonderful day! :)
