Answer:

D.

Step-by-step explanation:

Rate of change is another way of saying "find the gradient".

Sub any value into the gradient formula.

The rate of change = 55 / 1

The rate of change gives the cost per person to rent a fishing charter boat.

Rate of change = change in y / change in x

Therefore,

Rate of change = 165 - 110 / 3 - 2

Rate of change = 55 / 1

Rate of change = 55 / 1

The rate of change in this situation simply explains the change in the cost of renting a fishing charter boat per the change in the number people.

Answer:

The product of two numbers is 0 - hypotheses

At least one of the numbers must be 0 -conclusion

Step-by-step explanation:

The statement given in the question is a conditional statement because of the if and then factors attached to it. From this conditional statement, a hypothesis and conclusion can be derived. A hypothetical statement unlike a conclusive statement does not have a tone of finality to it. A hypothetical statement is subject to tests to prove its trueness after which a conclusion can be made.

It is indeed true that one of the numbers must be zero if the product of two numbers is zero.

Answer:

[tex]x=-1/8[/tex]

Step-by-step explanation:

Since this is a vertical line, our x-value stays constant no matter what y is.

So, the x is constant while the y changes.

Therefore, the equation of our vertical line will simply be the x-value of our coordinate point.

Our point is (-1/8, 4/3).

The coordinate is -1/8.

Therefore, our equation is:

Step-by-step explanation:

x=2:(-3)2=(-6)

not (-3)(-2) negative times negative is always positive, negative times positive is always negative

The coordinates of B are (-2, -6).

Given that the midpoint of AB is M(3, -1) and coordinates of A(8, 4).

We need to find the coordinates of B.

In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. The formula for the midpoint of a line segment with coordinates is (x, y)=((x1+x2)/2, (y1+y2)/2).

Let the coordinates of B be (a, b)

Now, (3, -1)=((8+a)/2, (4+b)/2)

⇒3=(8+a)/2 and -1 =(4+b)/2

⇒6=8+a and -2=4+b

⇒a=-2 and b=-6

Therefore, the coordinates of B are (-2, -6).

Answer:

Step-by-step explanation:

Answer:

The first step on how to solve the ratio is to write the values you want to compare and you can write such values in any given form like using colon or through division sign or by writing isto. Let’s understand the steps through an example. Suppose you want to take out the ratio of your maths and physics marks. You have got 90 marks in maths and 70 marks in physics. So firstly I will write it in the form of a ratio.  

90 is to 70 or 90:70 or 90/70.

Second step on how to solve the problem is to reduce the values into their simplest way. So for that you can take out the common factors from the numbers. And then we can divide both of the numbers from such a common factor so that we can get the numbers in their simplest form. For example we have a number 90 : 70 then after writing it in the format of ratios now you have to bring out the common factors between the terms of ratios. So in this example we have 10 as a common factor. Thus you will divide both the numbers 90 and 70 by 10 so that you get the numbers in their simplest form so you will get 90/10:70/10 = 9:7.

Thus the ratio is 9:7.

Let’s take another example of three digits and three digits are 75 marks in biology, 25 marks in physics and 100 marks in maths. So let’s first write it in the form of ratio that is  

75 : 25 : 100

Now we need to follow the next step of how to solve ratios. That is to find out the common factor from all the numbers thus we can clearly see that 25 is the common factor so you will have to divide each number with 25.  

75/25 : 25/25 : 100/25  

= 3 : 1 : 4

Thus the answer is 3:1:4.

The important point to learn in ratio is that it does not change with the multiplication or division of same numbers. It will remain the same. For example if you multiply the above number with 2 then they will become 75 x 2 : 25 x 2 : 100 x 2 = 150 : 50 : 200. Now also the ratio is same if you convert it to the smallest form then like first you have to divide it by 50 then you will find get the same ratio that is 3:1:2.  

You can also find the value of variables if two ratios are equal. Let’s take an example to understand it better. Suppose you have one ratio 3:2 and other ratio 5:x and these two ratios are equal and now you are required to find the value of x song the equation will be  

3 / 4 = 3/X

3 x X = 3 x 2  

X = 6/3

X= 2.

Answer:

16

Step-by-step explanation:

Using PEMDAS, anything in the parenthesis must be solved first which would make 8/2(2+2) turn into 8/2(4). Next for this equation according to PEMDAS, you must divide, turning 8/2(4) into 4(4), and 4 times 4 is 16. :)

Answer:

The initial distance between Wade and Alexandra is 240ft.

They walk towards each other.

Alexandra walks twice as fast as Wade.

Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.

Then:

if Wade walks z ft, Alexandra walks 2*z ft.

So we have the equation:

Distance that Wade walked + Distance that Alexandra walked = 240ft

z + 2*z = 240ft

3*z = 240ft

z = 240ft/3 = 80ft

They will meet when Wade walks 80ft.

Complete question :

Wade and Alexandra are 240 feet apart when they start walking toward one another. Alexandra walks twice as fast as Wade so whenever Wade travels x feet, Alexandra travels 2x feet. Let z represent the number of feet Wade has

traveled since he started walking toward Alexandra.

Write an expression in terms of z to represent the total number of feet Wade and Alexandra have walked toward one another.

b. Write an expression in terms of z to represent the distance (in feet) between Wade and Alexandra

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Initial distance between Wade and Alexandra = 240 feets

Alexandra walks twice as fast as wade :

Feets traveled by Wade = x

Feets traveled by Alexandra = 2x

Let z = feets traveled by wade since he started walking towards Alexandra

A.) Number of feets they've traveled towards one another in terms of z:

Number of feets traveled by wade = z

Number of feets traveled by Alexandra = 2z

Hence, total feets traveled towards one another :

(distance covered by Wade + distance covered by Alexandra)

= ( z + 2z) = 3z feets

B.) Distance between Wade and Alexandra:

Initial distance - distance covered

(240 - 3z) feets

extra part: -49+65=16

Answer:

The answer is 16

Step-by-step explanation:

equation of the line: y = -x-2

Step-by-step explanation:

First we need to find the slope of the line. In order to do that, we need to select 2 points.

I selected (-2, 0) and (-1, -1)

slope formula is:

[tex]m = \frac{y2-y1}{x2-x1}[/tex]

m = (-1 - 0)/(-1 - (-2))

m = -1/1

m = -1

We have the slope and now we need to find the y-intercept. According to the graph, the y-intercept is (0, -2) so the y-intercept which is "b" in the equation is -2.

So the equation of the given line is y = -x-2
