Answer: Michael has 87 comic books while David has 41 comic books.

Step-by-step explanation:

Let x represent the number comic books that Michael has.

Let y represent the number of comic books that David has.

Michael has 5 more comic books than double David's collection. The expression would be

x = 2y + 5

If together they have a total of 128 comics, it means that

x + y = 128- - - - - - - - - -1

Substituting x = 2y + 5 into equation 1, it becomes

2y + 5 + y = 128

3y + 5 = 128

3y = 128 - 5

3y = 123

y = 123/3

y = 41

Substituting y = 41 into x = 2y + 5, it becomes

x = 2 × 41 + 5

x = 87

Passes through (6 1) and is perpendicular to the line 3x-4y=2 standard form
Snowcat [4.5K]

Answer:

1⅓x + y = 9

Step-by-step explanation:

Convert the Standard Form of the given line to Slope-Intercept Form:

  1. -4y = -3x + 2 [Move -3x to the right side of the equivalence symbol]
  2. y = ¾x - ½ [Divide everything by -4]

Then, after getting your equation, take the OPPOSITE MULTIPLICATIVE INVERSE of ¾ [perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>(<em>SLOPES</em>)], which is -1⅓ [or -4⁄3]. After getting your slope, you can perform the action with your given ordered pair to find your y-intercept:

1 = -1⅓[6] + b

-8

9 = b

Now that you have your y-intercept, this is your new equation in <em>Slope-Intercept Form</em>:

y = -1⅓x + 9

We are not done just yet. The final step is to convert the Slope-Intercept Form of the line to Standard Form, and here is how it is done:

y = -1⅓x + 9

+1⅓x +1⅓x

--------------

1⅓x + y = 9 → Final equation

The function g(x)=-(x)^2+5. The function f(x)=-g(x+2).
Vitek1552 [10]
Short Answer f(x) down 5 units, left 2 units and right side up from g(x)
Step One

Find out what -g(x+2) is.
There are two steps to this. The first is to deal with the minus sign
(g(x)) = - x^2 + 5. Be very careful what you do next. 
Put brackets around both terms on the right.
g(x) = (-x^2 + 5) Now put the minus sign in front of g(x) and another one in front of the brackets.
-g(x) = - (-x^2 + 5) Remove the brackets.
-g(x) = x^2 - 5 

<em>Result</em>
So far g(x) moves down 5 units and opens upward. 

Step Two
The second step is to see what the x + 2 does.
-g(x + 2) = (x + 2)^2 - 5

The final result is that the graph opens upward, moves left 2 spaces and down 5.

There is a graph enclosed to show you the key steps.
The red graph is g(x) = x^2 - 5
The blue graph is g(x+2) = (x+2)^2 - 5
