There are three exams in your linear algebra class, and you theorize that your score in each exam (out of 100) will be numerical
Romashka [77]

Answer:

a) 40 hours

b) 60 hours

C) 100 hours

Step-by-step explanation:

0.2a + 0.3b+0.5c = 76

Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76

0.38 λ =76

λ = 76/0.38 =200

Thus : 40, 60, 100

Write a linear equation. Explain it in number please! 20 points!!!
juin [17]

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

    (-6,12)    and    (-5,14)

Now let us find the slope of the linear line:

 m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6}  = 2

   So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

      let us use the point (-6,12) and the slope of 2

      y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4

So the linear line is y = 2x + 4.

Hope that helps!
