Hello!

3x + 4 = 1

3x + 4 - 4 = 1 - 4

3x = -3

3x/3 = -3/3

x = -1

The solution of the equation 3x + 4 = 1 is -1.

The answer is:

C) x = -1

Work/explanation:

To solve this equation, I subtract 4 from each side:

\(\sf{3x+4=1}\)

Subtract :

\(\sf{3x=-3}\)

Divide each side by 3:

\(\sf{x=-1}\)

Hence, C is correct.

Answer:

12.   m∠C = 100° and m∠F = 100°

13.   m∠S = 89° and m∠U = 89°

Step-by-step explanation:

Question 12

The two triangles ΔABC and ΔDEF have two of their angles equal:
m ∠A = m ∠D

m∠B = m∠E

Therefore the third angles must be equal:
m∠C = m∠F

m∠C = (4x²)° and m∠F = (3x² + 25)°

Setting these two right side expressions in parentheses equal to each other gives
4x² = 3x² + 25
4x² - 3x² = 25
x² = 25
x = ±√25 = ±5

Ignoring the negative value we get
x = 5

Therefore
m∠C = (4x²)° = (4 · 5²)° = (4 · 25)° = 100°

Since, m∠F = m∠C ,
m∠F  = 100°

But we can double check
m∠F = (3x² + 25)° = (3 · 5² + 25)° = (3 · 25 + 25) = (75 + 25)° = 100°

Question 13

This is similar to question 12

The quadrilateral RSTU is divided into two triangles ΔRST and Δ RUT

We are given
m∠RTS = m∠TRU

m∠TRS = m∠RTU

Therefore the third angle of ΔRST must be equal to the third angle of Δ RUT

In other words,
m∠S= m∠U

Plugging in the expressions for each of these angles we get

(5x - 11)° = (4x + 9)°

Set the expressions inside parens equal to each other and solve for x:
5x - 11 = 4x + 9

5x - 4x - 11 = 9    (subtract 4x from both sides)
x - 11 = 9

x = 11 + 9  (add 11 both sides)

x = 20

m∠S= (4x + 9)° = (4 · 20 + 9)° = (80 + 9)° = 89°

Therefore m∠RUT is also 89°

but we can double-check
m∠U= (5x - 11)° = (5 · 20 - 11)° = (100 - 11)° = 89°

The inverse of the linear function, f(x), f(x) = (2x - 3)/5 is f⁻¹(x) = (5·x + 3)/2. The correct option is option A

A. f⁻¹(x) = (5·x + 3)/2

The inverse of a function is a function that reverses the effect the original function.

The original function is; f(x) = (2·x - 3)/5

The inverse of f(x) can therefore be found by making x the subject of the equation as follows;

f(x) = (2·x - 3)/5

5 × f(x) = (2·x - 3)

5 × f(x) + 3 = 2·x

2·x = 5 × f(x) + 3

x = (5 × f(x) + 3)/2

Plugging in x = f⁻¹(x) and f(x) = x, in the above equation, we get;

f⁻¹(x) = (5 × x + 3)/2

The correct option that is an inverse of f(x) is therefore, option A

Answer:

R = (0,-8)

Step-by-step explanation:

Let's look at the difference between S, and the midpoint M.

S(6,0) - M(3,-4) = N(3,4) This will help us find R(x,y)

Next, take M, and subtract N from it.

M(3,-4) - N(3,4) = (0,-8). This is the value of R.

Answer:

\(x<4\text{ or } x>4\)

Step-by-step explanation:

Solve we have the inequality:

\((x-4)^2>0\)

Let's solve it like a normal equation first. So, pretend the inequality is an equal sign:

\((x-4)^2=0\)

Solve for x. Zero Product Property:

\(x-4=0\text{ or } x-4=-0\)

Add 4 to both sides for both equations:

\(x=4\text{ or } x=4\)

So, our roots are at x=4 and x=4.

Since our original inequality is greater than, this means that our solution will be all values to the left of our first zero and all values to the right of our second zero.

Therefore, our solution is:

\(x<4\text{ or } x>4\)

Simply put, our x can be anything except for 4 itself.

And we're done!

Answer:

x<4 or x>4

Step-by-step explanation:

(x - 4)^2 > 0

Solving the first inequality

Add 4 to each side

x>4

Answer:

The least three-digit number which leaves a remainder of 1 when divided by 5 or 6 is 101.

Step-by-step explanation:

This is because 101 is the smallest three-digit number which is not a multiple of either 5 or 6. To see that 101 is the smallest such number, you can check that 100 and 99 are both multiples of both 5 and 6, and 98 is a multiple of 6.

Answer:

\(f(x) > \sqrt{1 -x}\)

which is the third choice

Step-by-step explanation:

We could just plot each and see which plot corresponds to the given graph

However, that is not necessary.

First note that the plot is a dotted line. This means the inequality is either a < inequality or a > inequality. If it were a ≤ or  ≥ inequality, the plot of the line would be a solid line

That eliminates first and last choices

To see which of the remaining two options fits the graph, take a point in the shaded region and see which one satisfies which inequality .

Checking second choice....

Point (0, 2) is in the shaded region
Does (0, 2) satisfy the second choice:  \(f(x) < \sqrt{1-x}\;\; ?\)
Let's check by substituting 0 for the value of x
\(1-x = 0\; so \; \sqrt{1-x} = \sqrt{0} = 0\)

But the corresponding value of y should be 2, not 0 so this inequality is not satisfied for a point in the shaded region. Eliminate second choice

Third choice is the correct answer

The box plots for Class A and Class B data show similar shapes and spreads. However, Class B has a slightly higher median, indicating students in that class may have more siblings on average.

To create box plots for the given data, we first need to sort the data in each class in ascending order.

Class A data: 0, 2, 2, 3, 4, 6, 9

Class B data: 2, 3, 3, 4, 5, 6, 6, 7

Now, let's create the box plots.

Class A Box Plot:

Minimum: 0

First Quartile (Q1): 2

Median (Q2): 4

Third Quartile (Q3): 6

Maximum: 9

Class B Box Plot:

Minimum: 2

First Quartile (Q1): 3

Median (Q2): 4.5

Third Quartile (Q3): 6

Maximum: 7

To compare the shape, center, or spread of the data between the two classes:

Shape: Both box plots appear to have a roughly symmetric shape, with similar box lengths and whisker lengths. This suggests that the distributions of the number of siblings in both classes are relatively similar.

Center: The median (Q2) for Class A is 4, while the median for Class B is 4.5. This indicates that the center of the data in Class B is slightly higher compared to Class A, suggesting that, on average, students in Class B may have slightly more siblings than those in Class A.

Spread: The spread of the data can be observed by comparing the interquartile ranges (IQR). The IQR for Class A is 4 (Q3 - Q1 = 6 - 2), and the IQR for Class B is also 3 (Q3 - Q1 = 6 - 3). This suggests that the spread of the data in both classes is relatively similar.

Overall, the two classes have similar shapes and spreads, but Class B appears to have a slightly higher center (median) compared to Class A.

a)The total expected waiting time is 37.5 minutes.

b)The total variance is 52.05 minutes^2.

c)The expected value of the difference between the total evening waiting time and the total morning waiting time over all 5 days is 12.5 minutes.

d)The variance of the difference between the total evening waiting time and the total morning waiting time over all 5 days is 28.95 minutes^2.

(a) To find the expected waiting time for the Caltrain in the morning, we calculate the expected value of the uniform distribution on [0, 5], which is (0 + 5) / 2 = 2.5 minutes. In the evening, the expected value of the uniform distribution on [0, 10] is (0 + 10) / 2 = 5 minutes.

So, the total expected waiting time for one morning and one evening trip is 2.5 + 5 = 7.5 minutes. For 5 days in a row, the total expected waiting time is 5 * 7.5 = 37.5 minutes.

(b) The variance of the waiting time for one morning trip is (5 - 0)^2 / 12 = 25 / 12 = 2.08. The variance of the waiting time for one evening trip is (10 - 0)^2 / 12 = 100 / 12 = 8.33. The total variance of the waiting time for one morning and one evening trip is 2.08 + 8.33 = 10.41. For 5 days in a row, the total variance is 5 * 10.41 = 52.05 minutes^2.

(c) The expected value of the difference between the total evening waiting time and the total morning waiting time over all 5 days is 5 * (5 - 2.5) = 12.5 minutes.

(d) The variance of the difference between the total evening waiting time and the total morning waiting time over all 5 days is 5 * (8.33 - 2.08) = 28.95 minutes^2.
