Using f(x) = 3x - 3 and g(x) = 2x, what is f(4) - g(2) ?

Zielflug [23.3K]

Answer:

5

Step-by-step explanation:

evaluate f(4) by substituting x = 4 into f(x) and g(2) by substituting x = 2 into g(x)

f(4) = (3 × 4) - 3 = 12 - 3 = 9

g(2) = (2 × 2 ) = 4

f(4) - g(2) = 9 - 4 = 5

What is the answer to this math question 2 1/12-5 5/6

AleksandrR [38]

<em><u>The solution is:</u></em>

$2\frac{1}{12} - 5\frac{5}{6} = \frac{-15}{4} \text{ or } -3.75$

<em><u>Solution:</u></em>

We have to solve the given expression

<em><u>Given expression is:</u></em>

$2\frac{1}{12} - 5\frac{5}{6}$

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

Thus we get,

$2\frac{1}{12} = \frac{2 \times 12 + 1}{12} = \frac{25}{12}$

$5\frac{5}{6} = \frac{ 5 \times 6 +5}{6} = \frac{35}{6}$

<em><u>Thus the given expression becomes,</u></em>

$2\frac{1}{12} - 5\frac{5}{6} = \frac{25}{12} - \frac{35}{6}$

Make the denominators same for easier calculations

$2\frac{1}{12} - 5\frac{5}{6} = \frac{25}{12} - \frac{35 \times 2}{6 \times 2}\\\\2\frac{1}{12} - 5\frac{5}{6} = \frac{25}{12} - \frac{70}{12}\\\\2\frac{1}{12} - 5\frac{5}{6} = \frac{25-70}{12}\\\\2\frac{1}{12} - 5\frac{5}{6} =\frac{-45}{12}$

<em><u>Reducing to lowest terms, we get</u></em>

$2\frac{1}{12} - 5\frac{5}{6} = \frac{-15}{4}$

<em><u>In decimal form, we get</u></em>

$\rightarrow \frac{-15}{4} = -3.75$

<em><u>Thus the solution is:</u></em>

$2\frac{1}{12} - 5\frac{5}{6} = \frac{-15}{4} \text{ or } -3.75$

When playing the lottery game Cash4Life, you must choose a cash ball number from 1 through 4. What is the probability that the r

Butoxors [25]

Answer:

$P(At\ least\ 2) = 0.75$

Step-by-step explanation:

Given

Balls = 1 to 4

Required

Determine the probability of selecting ball numbered at least 2

Here, we'll assume that all numbers have the same probability.

The probability of each ball will be:

$Probability = \frac{1}{4}$

So:

$P(At\ least\ 2) = P(2) + P(3) + P(4)$

Recall that

$Probability = \frac{1}{4}$ --- for each ball

So, the equation becomes

$P(At\ least\ 2) = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}$

$P(At\ least\ 2) = \frac{3}{4}$

$P(At\ least\ 2) = 0.75$

iren2701 [21]

Answer:

88 inches

Step-by-step explanation:

The given bicycle has a tyre that is 28 inches in diameter.

How far the bicycle moves forward each time the wheel goes around is the circumference of the bicycle tyre.

This is calculated using the formula:

C =\pi \: d

We substitute the diameter and

\pi = \frac{22}{7}

C = \frac{22}{7} \times 28

This simplifies to

C =22 \times 4

88 \: inches
