Answer:

slope: 2/5

y intercept: 1

equation: y=2/5x+1

Step-by-step explanation:

You can see that the line is positive. Using the rise/run method you can see that the slope is 2/5. The y intercept is found about by finding the point that the line as crossed on the y axis. Put this together to make your equation!

Serena estimates that she can paint 60 square feet of wall space every half-hour. Write an equation for the relationship with ti
Katarina [22]

Answer:

So, the relationship with i hours as the indecent variables would be  

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint =  

In i hours, she can paint =  

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

Now,  Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

<h2>Using the quadratic formula</h2>

The quadratic formula can help us solve for x in a quadratic equation:

x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}

We can use this when the given equation is organized in standard form: ax^2+bx+c=0

<h3>Applying this to the problem</h3>

2x^2+5x-4=0

First we can identify the values of a, b and c:

a = 2

b = 5

c = -4

Plug these values into the quadratic formula:

x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}

x=\dfrac{-5 \pm \sqrt{5^2-4(2)(-4)}}{2(2)}

x=\dfrac{-5 \pm \sqrt{25+32}}{4}

x=\dfrac{-5 \pm \sqrt{57}}{4}

<h2>Answer</h2>

Therefore, the two possible values of x are:

x=\dfrac{-5 +\sqrt{57}}{4}

x=\dfrac{-5 -\sqrt{57}}{4}
