Answer:

The graph that shows the translation f(x) = f(x) + 1 is the graph that is shifted upward by one unit on the y-axis. All the points on the graph have been moved upward by one unit, but the shape of the graph remains the same as the parent function.

The dotted line graph that shows the translation f(x) = f(x) + 1 is the one where the graph is shifted upward by one unit on the y-axis.

In the expression 2 − 5x − 4 + 8, the coefficient of x is -5. Thus, option a is correct.

A number or quantity combined with a variable is referred to as a coefficient. The variable is usually multiplied by an integer, which is then written next to it. It is assumed that the variables with no associated value have a coefficient of 1. For instance, in the expression 3x, the coefficient of x is 3, whereas in the expression x2 + 3, the coefficient of x2 is 1.

A variable's coefficient is the number or letter that the variable contains. As an illustration, the coefficient of variable x in the formula 2x + 3y is 2, and the coefficient of variable y is 3 in the same formula.

Step-by-step explanation:

The periodic fixed costs of the company, based on the cost function, are $1,000.

The fixed costs refer to the period costs that do not change in total concerning the production or activity level and they relate to a financial period.

The fixed cost per unit decreases as more units are produced and vice versa.  However, within the relevant range, the fixed cost for the period remains the same.

A cost function is a model or formula that shows the total costs based on different cost behaviors (fixed and variable) and the relationship of costs to the production quantity.

Cost functions can be used to predict the total costs to be incurred under different production levels.

In this situation, the cost function, C = 1000 + 3.75q, shows that the fixed cost per period is $1,000 and $3.75 per unit (variable).

Thus, based on the cost function, the fixed costs are $1,000.

Answer:

Domain {-3, 6}

Range: 7, 12}

Not a function

Step-by-step explanation:

Domain

Domain is the set of all x values which result in real and defined values for y

Range

Range is the set of y values that are possible from the values of x in the domain

Both are expressed in the form {min-value, max-value}

For x we see the minimum is -3 and maximum is 6

So domain = {-3, 6}

For y values we see the minimum is 7 and maximum is 12

So range = {7, 12}

A function can have only one output(y) for a specific input(x)

Here we see that for different values of x, x = 4 and x = -3, we get the same y-value

Hence it is not a function

Therefore , as a result, after answering the question, we may state that the coordinates are -(68,-69); the answer is = x - y - 137 = 0.

When locating points or other geometric objects precisely on a continuum, such as Euclidean space, a coordinate system is a technique that uses one maybe more integers or coordinates.

Complete question is here;

Answer:

Step-by-step explanation:

Is there enough evidence to reject the researcher claim?

To determine if there is enough evidence to reject the researcher's claim, we can perform a hypothesis test with a null hypothesis of p <= 0.05 (at most 5% of working college students are employed as teachers or teaching assistants) and an alternative hypothesis of p > 0.05 (more than 5% of working college students are employed as teachers or teaching assistants).

Find the critical values and identify the rejection.

For a one-tailed test with a significance level of alpha = 0.05, the critical value for a z-test would be 1.645. This means that if the calculated z-score is greater than 1.645, we would reject the null hypothesis.

Find the standardized test statistic z

To find the standardized test statistic z, we can use the formula:

z = (p-hat - p0) / (sqrt(p0 * (1 - p0) / n))

where p-hat is the sample proportion of working college students employed as teachers or teaching assistants (6%), p0 is the proportion specified in the null hypothesis (5%), and n is the sample size (400).

z = (0.06 - 0.05) / sqrt(0.05 * (1 - 0.05) / 400)

z = 0.1 / 0.015811388300841898

z = 6.317

Decide whether to reject or fail to reject the null hypothesis and interpret the decision.

Since the calculated z-score (6.317) is greater than the critical value (1.645), we can reject the null hypothesis. This means that there is enough evidence

Answer:

Step-by-step explanation:

First, we will use the property of radicals that states that (a √b) * (c √d) = (ac) √(bd). Since the expression has both multiplication and addition, we will break the expression down into its components and simplify each component separately.

6√x+7√(54) = 6√x + 7√(27*2) = 6√x + 7√27 * 7√2 = 6√x + 7√27 * (2*√2) = 6√x + 14√27 * √2 .

Next, we will simplify the second component of the expression: 12√(6) = 12√(2*3) = 12√2 * 6√3 = (4*3)√2 * 6√3 = 12√2 * 6√3.

Finally, we can combine the two separate parts of the expression to get the simplified version: 6√x + 14√27 * √2 - 12√2 * 6√3 = 6√x + 14√27 * √2 - 12√6.

The simplified version of the expression is 6√x + 14√27 * √2 - 12√6, in exact terms (no decimals).

Answer:

the down payment of 20000 is 10% of the purchase price of 200000.

Step-by-step explanation:

To calculate the percentage of the down payment to the purchase price, you can use the following formula:

(down payment / purchase price) x 100

So in this case:

(20000 / 200000) x 100 = 0.1 x 100 = 10

Therefore, the down payment of 20000 is 10% of the purchase price of 200000.

The cafe served 49 regular coffees.

You can use the proportion of regular coffees to the total number of coffees to find out how many regular coffees were served.

If 70% of the coffees served were regular, that means that 100-70 = 30% of the coffees served were decaffeinated.

To find out how many regular coffees were served, you can use the following proportion:

(Number of regular coffees) / (Total number of coffees) = 70% / 100%

You can then cross-multiply and solve for the number of regular coffees:

Number of regular coffees = (70/100) * (Total number of coffees)

Given the Total number of coffees = 70, you can substitute that and get:

Number of regular coffees = (70/100) * 70 = 49

Therefore, the number of regular coffees which the cafe served was 49.

Overview

To answer the question given, we have to find the point on the line that goes through the points given in the table when the x-axis represents the month of the year (1 is Jan, 2 is Feb, etc.) and the y-axis represents the average temperature for that month.

Method 1

I've attached a graph of the line for reference.

When we look at the graph of the line that goes through the points given in the table, we can determine that its y-intercept is (0, 28).

Method 2

To determine the y-intercept of the line without actually graphing it, we can construct an equation using the given points.

We know that the line's slope is defined as [tex]\dfrac{\textrm{rise}}{\textrm{run}}[/tex].

Using that information, we can solve for the line's slope by using any two of the given points. I will use the points for January (1, 42) and February (2, 56).

[tex]\textrm{slope} = \dfrac{56-42}{2-1} = \dfrac{14}{1} = 14[/tex]

Then, we can plug this value into the point-slope form equation

[tex]y - b = m(x - a)[/tex]

along with one of the given points [tex](a,b)[/tex] -- I'll use January (1, 42):

[tex]y-42=14(x-1)[/tex]

Next, to solve for the y-coordinate of the line's y-intercept, we can plug 0 into the equation for x and solve for y.

[tex]y - 42 = 14(0 - 1)[/tex]

[tex]y - 42 = 14(-1)[/tex]

[tex]y - 42 = -14[/tex]

[tex]y = -14 + 42[/tex]

[tex]y = 28[/tex]

Finally, we can plug the solved y-coordinate and 0 for the x-value (because we solved for when y when x = 0) into the format of a Cartesian coordinate:
