Answer:

f(x) = -5/3x + 5/3

Step-by-step explanation:

if x = 4 ; f(x) = -5

if x = -2 ; f(x) = 5

f(x) = ax + b

-5 = 4a + b <em>(</em><em>1</em><em>)</em><em> </em>

and

5 = -2a + b <em>(</em><em>2</em><em>)</em>

<em>(</em><em>1</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em>

2a + 2b = 0

a = -b

<em>(</em><em>1</em><em>)</em><em> </em>-5 = 4a - a

-5 = 3a

a = -5/3

<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u> </u><u>:</u>

f(x) = -5/3x + 5/3

Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
yuradex [85]

When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.

We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped

15P/50

8B/50

2G/50

18C/50

7S/50 for a total of 50 marbles

Now we use the chart to decide our awnsers  

A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.

B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely

C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these

D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of  these and gives us an even to likely chance of getting one of these.

E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

What is the simplest form of
11111nata11111 [884]

Answer:

  1. 15 = -3c +12
  2. -3n +8 = -7
  3.  5z -40 = 10
  4. 3.4s -35 = 50

Step-by-step explanation:

Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.

We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

__

1. 15=-3(c-1)+9

  15 = -3c +3 +9

  15 = -3c +12 . . . . . simplified form of the given equation

  -1 = c . . . . . . . . . . "simplest" form

__

2. 2(1.5n+4)-6n=-7

  3n +8 -6n = -7

  -3n +8 = -7 . . . . . . simplified form of the given equation

  n = 5 . . . . . . . . . . . "simplest" form

__

3. 2(z-20)+3z=10

  2z -40 +3z = 10

  5z -40 = 10 . . . . . . simplified form of the given equation

  z = 10 . . . . . . . . . . "simplest" form

__

4. 2/5s -2+3(s-11)=50

  0.4s -2 +3s -33 = 50

  3.4s -35 = 50 . . . . simplified form of the given equation

  s = 25 . . . . . . . . . . "simplest" form
