Find the equation in standard form , of the line passing through points (2,-3) and (4,2)
Fudgin [204]

The form of linear equation that describes line is:

y=sx+n

First we must calculate the slope.

s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}

Now it looks a bit more like this:

y=\dfrac{5}{2}x+n

All we need now is to put in y and x from one point doesn't matter which. I'll pick A.

The equation now looks like this:

-3=\dfrac{5}{2}\cdot2+n

Solve for n.

-3=5+n \\n=-8

And finally write the equation.

f(x)=\dfrac{5}{2}x-8

Hope this helps.

Show that the equation x^2 +6x -5 has a solution between x=0 and x=1
Firdavs [7]

Answer:

f(0)= 0^2+0-5= -5

f(1)=1+6-5= 2

Step-by-step explanation:

To do this we just plug in 0 for x and then 1

if the sign of the answer changes that must mean that the line crosses the x axis (which obviously means there's a solution)

f(0)= 0^2+0-5= -5

f(1)=1+6-5= 2

True or False: In scientific notation a number is written m X 10^w where m is between 1.000 and 9.999...
Bogdan [553]

Answer: True

Step-by-step explanation:

We try to keep the number greater than 1 and lower than 10, so between 1, and 9.

For example: 3545346 would be 3.5x10^6

you can see 3.5 is between 1 and 9
