Step-by-step explanation:

-2(x+3) =

According to the distributive property:

(-2*x) + (-2*3) =

-2x - 6

Answer: -2x-6

Explanation : we apply the distributive property which would mean -2 times x which would be -2x and then we would switch the positive to a negative since all of the numbers are negative and -2 times 3 equals -6 so that is why that is the answer have a nice day (:

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]

Answers

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

Which function is represented by the graph?

Answers

9514 1404 393

Answer:

f(x) = -2|x| +1

Step-by-step explanation:

The vertical translation is 1 unit upward, and there is no horizontal translation. So, the function will be something of the form ...

f(x) = a|x| +1

The slopes of the lines have a rise/run with a magnitude of 2/1, so the value of 'a' will have a magnitude of 2. The appropriate choice is ...

f(x) = -2|x| +1

Can someone please help me figure this out (trig) (pre calc)

Answers

Answer:

1. x = 1.5 rpm

2. x ≈ 0.8182 mi/hr

3. x = 6.6 feet

4. x = 4224 rpm

5. x = 390 rpm

Step-by-step explanation:

The relationship between angular speed and linear speed is given as follows;

Angular speed, ω = Linear speed, v/(Radius, r)

Therefore, we have;

1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm

2. When, ω = 4 rpm, and r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr

3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet

4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm

5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

Given a mean of 80 and a standard deviation of 3, label the normal curve below.

Answers

Answer:

The points from the left;

71, 74 , 77, 80, 83, 86 , 89

Step-by-step explanation:

Here, we want to label the normal curve given the mean and the standard deviation

From what we have, the central part is the mean while the other parts are deviations from the mean

We will label the graph starting from the left to the right

1 is 3 SD from the mean (negatively)

That will be 80-3(3) = 80-9 = 71

2 is 2 SD away

That will be;

80 -2(3) = 80-6 = 74

The 3rd part is 1 SD away

That will be 80-3 = 77

The midpoint is for the mean which is 80

The point after this will be;

80 + 3 = 83

The point after this will be;

83 + 3 = 86

Next is

86 + 3 = 89

Need help on number 5!

Answers

a. To find the mean, you first have to add all of the numbers together. Keep in note that if there is more than 1 dot above the number, such as 2 or 3 dots, then you must add the the amount of dots there are above it. Next, you want to divide the total amount of the numbers by the total amount of numbers you have added to get this. That will be the mean. The mean represents the average amount of wage the college students earn during a 1-week span.

b. Next, you want to find the median. Put all of the numbers together in a line, ranging from smallest to largest. Whatever number is in the middle is going to be your median. Keep note for this as well that if there is, for example, 2 dots above the number, you will have to write the number two times. The median helps interpret the middle, and separates the lower, and high values.

c. No, a box plot is not the same as a dot plot. It can interpret the median, but not the mean. A box-and-whisker plot is usually used when you want to find the IQR (interquartile range).

Answer:

D. x=1

Step-by-step explanation:

Image can be rewritten as 3x + 6 = 9.

Solve for x.

Isolate x by subtracting 6 from both sides.

3x = 3

Get rid of the 3 by dividing by 3 on both sides.

x+2/2x-6=3/8 solve using multiplication property of equality

Answers

The solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

What are expressions?

Expressions are mathematical statements that are represented by variables, coefficients and operators

How to solve using multiplication property of equality?

The equation is given as

x+2/2x-6=3/8

Apply the multiplication property of equality.

So, we have

8(x + 2) = 3(x - 6)

Open the brackets

8x + 16 = 3x - 18

Collect the like terms

5x = -34

Divide both sides by 5

x = -34/5

Hence, the solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

Answer:

y = 65x + 250

Step-by-step explanation:

Let the linear equation representing the relation between total pay and number of computers sold be,

y = mx + c

Here, m = commission on every computer sold = slope of the linear function

c = weekly salary

y = total pay

x = number of computer sold each week

Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table attached,

Slope of the line passing through (4, 510) and (6, 640),

m = [tex]\frac{640-510}{6-4}[/tex]

= 65

Equation of the line will be,

y = 65x + c

Since, this line passes through (4, 510),

510 = 65(4) + c

c = 510 - 260

c = 250

Therefore, equation of the line will be,

y = 65x + 250
