7. The Steps Below Show Cam's Work In Solving An Equation. Circle The Line Where He Makes A Mistake.

Answers

Answer 1

Answer:

Error was at the fourth line: 12 = 16x

Correct solution: x = ½

Step-by-step explanation:

Let's solve the equation step by step to find the correct solution, and also, to find out at which line Cam made a mistake.

10 - 2x = 19x + 2 - 5x (given)

10 - 2x = 19x - 5x + 2

10 - 2x = 14x + 2

Add 2x to both sides

10 - 2x + 2x = 14x + 2 + 2x

10 = 14x + 2x + 2

10 = 16x + 2

Subtract 2 from both sides

10 - 2 = 16x + 2 - 2

8 = 16x (this is where Cam made an error, at the fourth line. He wrote: 12 = 16x. It seems Can only subtracted 2 from the right, then added 2 to the left. Subtraction property of equality was not properly done.)

Proceeding further with our calculation, we would divide both sides by 16

8/16 = 16x/16

½ = x

x = ½.

Let A (10, 11, 12, 13 and B (a, b, c, d) Let g be a function from A to B defined by f(10, a), (11,a), (12, b), (13,b)) What is the inverse image of d?

Answers

Answer:

d does not have an inverse image

Step-by-step explanation:

From the question we are told that

    The  first set is    A (10, 11, 12, 13 )

     The  second set is     B (a, b, c, d)

      The function that from A to B is  f(10, a), (11,a), (12, b), (13,b))

Generally for a function defined by (x,y), y is the image of x while x is the inverse image  of  y

Now considering the function we are given and the value d we see that and inverse image is not defined for d in the function

hence d does not have an inverse image

The 13 moose are the individuals. There are four categorical variables and one quantitative variable.
Next

Answers

The correct answer is C. The 13 moose are the individuals. There is one categorical variable and four quantitative variables.

Explanation:

In research, the individuals refer to the participants or population that is being analyzed. For example, if the purpose of the research is to know how many hours highschool students sleep, the individuals are high school students. In this context, the individual or population of this study ae the 13 moose.

Moreover, this research focuses on different variables such as gender, height, the number of hours each moose spends in the water, the weigh of the food eaten on average by each moose, and the average weight of food eaten every day. From these variables, the last four variables are quantitative because they can be measured using numbers, for example, the height is measured in inches. On the other hand, the first variable is categorical because each moose can be classified in only two categories: male or female.

Step-by-step explanation:

add 4x to both sides of the equal sign so then you'd have -2x + 14 = 32

then subtract 14 from both sides to where you have -2x = 18

then divide both sides by -2 and get x= -9

solve for z: 11=6|-2z| -5

Answers

Answer:

the roots are {-4/3, 4/3}

Step-by-step explanation:

Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:

11=6|-2z| -5 becomes 16 = 6|-2z|.

Dividing both sides by 12 yields

16/12 = |-z|

There are two cases here:  first, that one in which z is positive and second the one in which z is negative.

If z is positive, 4/3 = -z, and so z = -4/3, and:

If z is negative, 4/3 = z

Thus the roots are {-4/3, 4/3}

What are domain and range?

The domain means all the possible values of x and the range means all the possible values of y.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

From the graph, the maximum value of the line segment will be 3 and the minimum value of the line segment will be negative 3. Then the range can be given as,

R = [-3, 3]

- 3 ≤ y ≤ 3

The range of the line segment will be - 3 ≤ y ≤ 3. Then the correct option is A.

given f(7)=4, f'(7)=10, g(7)=-1, g'(7)=8, find the values of the following: 1. (fg)'(7) = 2. (f/g)'(7) =

By the product rule,

What is the slope of the line that passes through the points (-2,8) and (-22,8)? Write your answer in simplest from

Answers

Answer:

[tex]\boxed{\tt m=0}[/tex]

Step-by-step explanation:

The slope formula is:

[tex]m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

where (x₁, y₁) and (x₂,y₂) are the points on the line.

The points given are (-2,8) and (-22,8). Therefore,

[tex]x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8[/tex]

Substitute the values into the formula.

[tex]m=\frac{8-8}{-22--2}[/tex]

Solve the numerator. Subtract 8 from 8.

[tex]m=\frac{0}{-22+2}[/tex]

Zero divided by any number is zero, so we automatically know the slope is zero.

[tex]m=0[/tex]

The slope of the line is 0

Answer: 0

Step-by-step explanation:

To find the slope, you need to use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You use the given points to plug in and solve.

[tex]m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0[/tex]

Now, we know that the slope is 0 meaning this is a horizontal line.

At least one of the numbers must be 0.
