I'm going to set up an equation to find the amount of momey Elisa has, then we can check our answer

e + 2e + 2e + 5 + 2e + 5 · 3 + e + 2e = 69
Simplify:
10e + 30 = 69
Subtract 35 from each side:
10e = 39
Divide by 10 on each side
e = 3.9

We can check our answer by putting the value in the simplified equation.
10 · 3.9 + 30 = 69
Yep! The equation is correct. Now for the answer.

Elisa
3.9
Jacob
7.8
Sandra
12.8
Damian
38.4
Martin
11.7

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)

Answer:

  • f(x) = x
  • g(x) = -2x+1
  • f(x) -(-g(x)) = -x+1
  • f(x) +g(x) = -x+1
  • f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not

Step-by-step explanation:

We can define a couple of linear functions as ...

  f(x) = x

  g(x) = -2x+1

Then the reflected function -g(x) is ...

  -g(x) = -(-2x +1) = 2x -1

And the difference from f(x) is ...

  f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))

We want to compare that to the sum of the functions:

  f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)

The two versions of the function expression have the same value.

These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.

linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4
RoseWind [281]

Answer:

  (c)  y-2 = -4(x-3)

Step-by-step explanation:

The point-slope equation of a line is ...

  y -k = m(x -h) . . . . . . line through point (h, k) with slope m

For (h, k) = (3, 2), and m = -4, the equation of the line is ...

  y -2 = -4(x -3)
