The area of each figure can be calculated using the given dimensions. Which of the
figures has an area formula that is a linear function?

Answer:

  y = -3

Step-by-step explanation:

You want the equation of a line with slope 0 through the point (-2, -3).

The point-slope form equation for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Adding k to both sides gives the "y =" form ...

  y = m(x -h) +k

When m=0 and (h, k) = (-2, -3), this becomes ...

  y = 0(x -(-2)) + (-3)

  y = -3 . . . . . . simplified

__

Additional comment

Anything times 0 is 0. So, the product 0(x +2) is 0.

Anything added to 0 is unchanged. So, the sum y = 0 -3 is y = -3.

When the slope is zero we get y= -3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

As, the Point-slope form

The point-slope form equation for a line with slope m through point (h, k) is

y = mx + b

When m=0 and (h, k) = (-2, -3)

y = 0(x -(-2)) + (-3)

y = -3

Answer:

Step-by-step explanation:

Josslyn burns 7 calories per minute while swimming and 5 calories per minute while practicing yoga. Let x be the number of minutes she spends swimming and y be the number of minutes she spends practicing yoga.

The total number of calories burned, C, is given by:

C = 7x + 5y

To burn at least 500 calories each day, we can write the inequality:

7x + 5y ≥ 500

This inequality states that the total number of calories burned from swimming and practicing yoga, 7x + 5y, must be greater than or equal to 500. Josslyn can achieve this goal by spending a combination of x minutes swimming and y minutes practicing yoga.

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Given:

Two events take place.

Let event A be flipping a coin

Let event B be rolling a 6-sided die.

Now, a coin has two faces; one is the head and the other is the tail.

So, the possible outcomes of event A are: {H, T}

H → Head, T → Tail.

Now, a six-sided die has six faces each marked with a number. The numbers marked ranges from 1 to 6.

So, the possible outcomes of event B are {1, 2, 3, 4, 5, 6}

Now, each element of set A should match all the elements of set B.

Now, the tabular form should have a row of outcomes of B and a column of outcomes of event A. Thus,

Outcomes          1          2       3        4         5          6

Answer:

Step-by-step explanation:

I = prt

I = interest earned

p = principal = amount invested

r = interest rate; 5.25% = 5.25/100 = 0.0525

t = time in years; 6 months = 0.5 years

$4,000.00 at 5.25% interest

I = 4000 × 0.0525 × 0.5 = 105

$105 interest in 6 months

To show how c and b are related, we can draw a line through these points. A positive sloped straight line should appear on the graph.

Identifying the slope and y-intercept is necessary before putting the equation in y-intercept (y=mx+b) form and figuring out the equation of a graphed line. The slope is the y-to-x change ratio.

Plotting points on the coordinate plane with values for b and calculating the appropriate values for c is necessary to graph the equation c = 2b + 6.

Let's pick some b values and determine the matching c values:

c = 2(0) + 6 = 6 when b = 0.

If b = 1, then c = 2(1) + 6 = 8.

c = 2(2) + 6 = 10 when b = 2

These points can be used to plot the graph:

Set the scene (0, 6)

An equation is a mathematical statement that shows that two expressions are equal. It consists of two parts: the left-hand side (LHS) and the right-hand side (RHS), separated by an equals sign (=). The equals sign indicates that the two expressions are equal, and the goal of solving the equation is to find the value of x that makes this statement true. Equations can be solved using various algebraic techniques, such as simplifying and rearranging the expressions, applying operations to both sides of the equation, and factoring or expanding expressions. Solving an equation involves finding the values of the variables that make the equation true.

The size of each payment for the sinking fund must be $1586.87.

A sinking fund is a collection of funds that have been put up or saved to pay off bonds or debts. A corporation that issues debt will eventually have to pay that loan back, and the sinking fund lessens the burden of a significant outflow of revenue. The corporation creates a sinking fund so that it may make contributions to it in the years before the bond matures.

The sinking fund formula is given as:

A = P * ((1 + r/n)ⁿˣ - 1) / (r/n)

61000 = P * ((1 + 0.009833/6)⁽⁶⁽⁹⁾ ⁻ ¹⁾/ (0.009833/6)

In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another.

percent error is calculated as follows: 100% divided by (actual value - measured value).

Whereas, "|" stands for absolute value.

In this instance, the measured measurement is 8.5 inches, whereas the real value is 9.1. Hence, by entering these values into the formula, we may obtain:

What is verbal sentence ?

Verbal sentences consist of a verb + subject + object or adverbial phrase. The subject and object can be either nouns or pronouns.

After solving the equation we get square of n which is equal to three times of eight

If the subject is a pronoun, it is always a suffix; and if the object is pronoun, it is always a dependent pronoun. When the subject is a pronoun, the word order is normal, meaning that the subject follows the verb and precedes the object.

If the subject is a noun and the object is a dependent pronoun, the pronoun object is before the noun subject.

The dative has a special place in the word-order of verbal sentences. It is expressed by the preposition n in addition to a noun or pronoun referring to a person, if the subject is a pronoun. It assumes a third place following the verb and its subject. However, if the subject is a noun, the dative is allocated a forward position and occurs before the subject.

If the subject is a noun and the object is a pronoun and the sentence consists of a dative, the word order is thus:

The probability and the likelihood, that the marble drawn is not red is high which is 4/5.

To determine how likely something is gonna occur, use probability. Several things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty.

It is stated that there is a 2/10 chance of drawing a red marble at random.

We can deduct the likelihood of drawing a red marble from one to determine the likelihood that the drawn marble is not red (since the probability of an event and its complement add up to 1).

So, the probability of drawing a marble that is not red is -

1 - 2/10 = 8/10 = 4/5

Therefore, the probability that the marble drawn is not red is 4/5.

The likelihood of an event is a measure of how plausible it is, given some evidence or knowledge.

In this case, we can say that the likelihood of drawing a marble that is not red is high, since there are more marbles in the jar that are not red than those that are red.

Therefore, the likelihood of drawing a marble that is not red is high.
