Evaluate the function found in the previous step at X =-3
babunello [35]
x-5y=-4x-2y

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

-3-5y=-4(-3)-2y

<em>Multiply -4 and -3 in the function above.</em>

-3-5y=12-2y

<em>Add 3 on both sides of the equation.</em>

-3-5y+3=12-2y+3-5y=15-2y

<em>Add 2y on both sides of the equation.</em>

-5y+2y=15-2y+2y-3y=15

<em>Divide both sides of the equation by -3.</em>

\frac{-3y}{-3}=\frac{15}{-3}y=-5

Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.

Answer:

f(-3) = -5

3. Calvin has a bucket of marbles. The table shows the number of marbles of each color Color Amount Red Blue 3 Yellow 4 Green Ca
dalvyx [7]

The false statement is (c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

<h3>What are probabilities?</h3>

Probabilities are used to determine the chances of events

The table entry is given as:

  • Red  - 2
  • Blue - 3
  • Yellow  - 4
  • Green - 3

From the list of options, the false statement is

(c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

This is so because:

  • Blue or Yellow = 3 + 4 = 7
  • Red or Green = 2 + 3 = 5

Notice the count of blue or yellow marbles (7) is greater than the number of  red or green marbles (5)

This means that, the probability of selecting a blue or yellow marble is greater than the probability of selecting a red or green marble.

What is the best first step for solving the given system using substitution while avoiding fractions? =9x+4x=10 -9x+3y=3
aivan3 [116]

Answer:

  Solve for y in the second equation

Step-by-step explanation:

We assume your system is ...

  • -9x +4y = 10
  • -9x +3y = 3

Dividing <em>the </em><em>second equation</em> by 3 gives ...

  -3x +y = 1

so an expression for y without fractions can be found by <em>solving for y</em>, that is, by adding 3x:

  y = 3x +1

_____

<em>Comment on alternate solution</em>

We'd be tempted to solve the first equation for -9x and substitute for that.

  -9x = 10 -4y

  (10 -4y) +3y = 3 . . . . . substitute for -9x

  -y = -7 . . . . . . . . . . . . . simplify, subtract 10

  y = 7 . . . . . . . . . . . . . . multiply by -1
