Both Aiden's and Natalie's tennis balls can cover the same distance of the catapult length is 40.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

Given:

As, we know the linear intercept form,

y = mx + b

Where m is the rate of change (slope) and b is the initial value of y.

Now, From the graph of both Aiden's and Natalie's data, we can see that the point of intersection is at (-40, 90).

Also, which shows x axis at 40 is the distance.

So, Both of them Aiden's and Natalie's tennis balls can cover the length of 40.

The solution set of the given system is (5/7, 12/7).

Now, According to the question:

The given equations are:

5x + 2y = 7 …. (1)

y = x + 1 ….. (2)

Let us solve the system of linear equations using the substitution method.

Substituting equation (2) in (1)

5x + 2(x + 1) = 7

By further calculation

5x + 2x + 2 = 7

So we get

7x = 7 - 2

7x = 5

Divide both sides by 7

x = 5/7

Substitute the value of x in equation (2)

y = 5/7 + 1

Taking LCM

y = (5 + 7)/7

y = 12/7

Therefore, the solution set of the given system is (5/7, 12/7).

The factor of xy 3y − 7x − 21 is x − 3.

xy 3y − 7x − 21 = x(y 3y − 7) − 21 = x(y 3y − 7) − 3(7) = (x − 3)(y 3y − 7)

The expression xy 3y − 7x − 21 can be simplified by factoring out the greatest common factor, which in this case is x. We can factor out an x by dividing the entire expression by x. This gives us y 3y − 7 − 21/x. Now, we can look for a common factor between the two terms. In this case, the factor is -3. We can factor out -3 from both terms to get -3/x and y 3y − 7. This can be rewritten as (x − 3)(y 3y − 7). Therefore, the factor of xy 3y − 7x − 21 is x − 3.

To explain further, factoring is the process of breaking down an expression into its factors. A factor is a number, variable, or expression that can be multiplied to produce the original expression. In this case, we are looking for the factors of xy 3y − 7x − 21. To find these factors, we first simplify the expression by factoring out the greatest common factor, which in this case is x. We then look for a common factor between the two terms, which is -3. We factor out -3 and rewrite the expression as  

(x − 3)(y 3y − 7). This means that the factor of xy 3y − 7x − 21 is x − 3.

Based on the attached boxplot, approximate percentage of the people who entered the amusement park met the height requirement for the attraction is 50%.

A boxplot is a way to present a five number summary in a box chart. The main part of the box shows where the middle portion of the data, the interquartile range. At the ends of the box, we will find the first quartile (Q1 or the 25% mark) and the third quartile (Q3 or the 75% mark). The bottom of the box is the minimum (the smallest number in the set) and the top of the box is the maximum (the largest number in the set). And, the median is represented by a line in the center of the box.

From the boxplot can be seen that:

Minimum = 43

Maximum = 64

Q1 (first quartile) = 46

Q3 (third quartile) = 58

Median = 48

In the passage, given that a person must be at least 48 inches tall to ride the attraction. So, this is the same number as median value, that is 48. Thus, 50% the amusement visitors are eligible for the requirement, and the 50% others are not.

The scale factor of two similar circles is equal to the ratio of their radii.

This can be expressed mathematically as a fraction, where the numerator is the radius of the larger circle, and the denominator is the radius of the smaller circle. For example, if the radii of the two circles are 3 cm and 6 cm, then the scale factor is 3/6 or 1/2. To find the scale factor, divide the radius of the larger circle by the radius of the smaller circle. For example, if the radii of the two circles are 10 cm and 4 cm, then the scale factor is 10/4, or 5/2.

Isolating x in the second equation, the expression that would be replaced into the first equation to solve the system of equations is given as follows:

b. -3y + 12.

The system of equations for this problem, with variables x and y, is defined as follows:

The second equation of the system is given as follows:

-x - 3y = -12.

The first step to isolate x is move the -3y term to the opposite side of the equality, with an addition symbol, which is the inverse of the negative symbol, hence:

-x = 3y - 12.

As the leading coefficient of x is negative, the entire expression must be multiplied by -1, hence:

x = 12 - 3y.

x = -3y + 12(commutative property).

Meaning that the correct option is given by option b.

Answer: (b) -3y + 12.

To use the Substitution Method, we would isolate x in the second equation, which gives:

-x = 3y - 12

Multiplying both sides by -1, we get:

x = -3y + 12

We can then substitute this expression for x into the first equation, which gives:

2(-3y + 12) + y = 8

Simplifying this expression, we get:

-5y + 24 = 8

Subtracting 24 from both sides, we get:

-5y = -16

Finally, dividing both sides by -5, we get:

y = 16/5

Therefore, if we isolate x in the second equation, we would substitute x = -3y + 12 into the first equation.

So the expression we would substitute into the first equation is -3y + 12.

The probability of the two cards being A and A, P(A, A), is 1/9.

The correct option is the second option, one ninth.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

A set of 3 cards, spelling the word ADD, are placed face down on the table.

And we have to determine P(A, A) if two cards are randomly selected with replacement.

From the formula for probability, we have that

P(A) = Number of favorable outcomes / Total number of possible outcomes

P(A) = 1/3

Then,

The probability of selecting two cards that have A and A with replacement is,

P(A, A) = P(A) × P(A)

P(A, A) = 1/3 × 1/3

P(A, A) = 1/9

Therefore, the probability is 4/9.
