Nataly [62]

Answer:

Option D.

Step-by-step explanation:

The given quadratic equation is

$y=x^2+7x+10$

We need to draw the graph of given equation by using graphing calculator as shown below.

From the graph it is clear that the parabola intersect the x-axis at points (-2,0) and (-5,0). So, the x-intercepts are (-2,0) and (-5,0).

Therefore, the correct option is D.

2/5 of a number is what percentage of that number?

Law Incorporation [45]

Answer:

40%

Step-by-step explanation:

In order to find percent, you can set up the fraction 2/5 to the equation x/100.

$\frac{2}{5}=\frac{x}{100}$

Then solve using algebra to cross-multiply.

$(2*100)=(x*5)$

$200 = 5x$

$x = \frac{200}{5} = 40$

so the answer is 40%.
