Mai uses Triangle A and says the slope of this line is `\frac{6}{4}.` Elena uses Triangle B and says no, the slope of this line

nikdorinn [45]

Answer:

I agree with both of them because they are both correct

Step-by-step explanation:

See attachment for complete question;

Slope (m) is calculated using the following formula:

$m = \frac{Rise}{Run}$

Where

$Rise = Vertical\ Distance$

$Run = Horizontal\ Distance$

From the attachment, we have the following:

Triangle A

$Rise = 6\ units$

$Run = 4\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{6}{4}$

In this case, Mai is correct:

Triangle B

$Rise = 1.5\ units$

$Run = 1\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{1.5}{1}$

$m = 1.5$

In this case, Elena is also correct:

If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)

Lelu [443]

Hello :
If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)
(f+g)(x)= f(x) +g(x) = x/2-2 +2x²+x-3 = x/2 +2x²+x-5
(f+g)(x)= (x+4x²-2x-10) /2
(f+g)(x)= (4x²+3x-10)/2 = 2x²+3/2 x -5
