Solve x^2 - 3x - 10 = 0

Mathematics
1 answer:
Pachacha [2.7K]2 years ago
6 0

Answer:

5 and -2

Step-by-step explanation:

{x}^{2}  - 3x - 10 = 0

{x}^{2}  - 5x + 2x - 10 = 0

x(x - 5) + 2(x - 5) = 0

(x - 5)(x + 2) = 0

x - 5 = 0

x = 5

or

x + 2 = 0

x =  - 2

How do you write the equation of a line (in slope intercept form) with three given points?​
Mrrafil [7]

With even just two points, you can find the equation of a line in slope-intercept form.

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept

<u>1) Solve for the slope (</u>m<u>)</u>

The equation to solve for the slope is m=\frac{y_2-y_1}{x_2-x_1} when the two points are (x_1,y_1) and (x_2,y_2). Plug the coordinates of these points into the equation and solve for m.

Then, plug m into y=mx+b.

<u>1) Solve for the y-intercept (</u>b<u>)</u>

Then, take any of the given points and plug it into y=mx+b along with the slope. Isolate b to get the y-intercept. Then, plug both m and b back into y=mx+b to get your final equation.

I hope this helps!

Which interval contains a local minimum for the graphed function?
DochEvi [55]

Answer : Option D is correct i.e [2.5,4]

Explanation :

Suppose our function is f(x)

then the value of f(x) is minimum where

it reaches -0.44 and 3 with two different intervals .

As we know that for finding the local minimum ,

the criteria is that  f'(x)=0 .

So, here

f'(-0.44)=0 and

f'(3)=0

both are the local minimum point for the function f(x)

but -0.44 is the global minimum point .

In our case for [2.5,4] is the required interval where f(x) reaches its  local minimum.
