Help me round to the nearest tenth 5x^2-27=6x
Ray Of Light [21]

Answer:

-1.8,3

Step-by-step explanation:

This type of problem often results in two answers for X, and to get it, I often like to rearrange the formula to look like this: 5x^2-6x-27. There are various ways to answer this question, but since this is a quadratic equation, I commend using the quadratic formula! It may look scary, but it is actually really simple. I will attach a picture of this formula for reference when you need it.

looking at our modified formula, a= 5, b=-6, and c= -27. With these values in mind, you can go ahead and plug them in the formula. So it will look like (6±√(-6)²-4(5)(-27) )÷2(5).

Let’s break this down a bit, what this formula is saying is that you’ll have 2 operations to do now, the first one will look like this:

(6+\sqrt{576})/10, this will result in 3, which is one of your values for x

the second operation will be exactly the same, but instead of adding 6 to the square root of 576 (pssst, it is 24 btw), you will be subtracting. This second operation once done will result in -1.8, which is rounded to the nearest tenth!

If you are told the y-intercept is -4, what is the ordered pair for the y- intercept?
jek_recluse [69]

Answer:

(0,-4)

Step-by-step explanation:

The y-intercept is where the line intersects the y-axis. The y-intercept is written in the form (0,x), where x = y-coordinate/y-intercept. Thus, the answer is (0,-4).

\mathfrak {last \:option }

\mathfrak\blue{ {option \: 2} }

Step-by-step explanation:

x intercept of a function is the point where it's graph intersects the x axis.

or

simply that value x, where the value of y is 0.

since at x = 2; f(x) =0 that point <u>(2, 0)</u> is the x intercept of the function.
