Ana and Ling are solving |3x + 14| = -6x.
Is either of them correct?...............................
Explain your reasoning.

Answers

Answer:

No! Both are wrong!

Step-by-step Explanation:

the value of absolute function, (|.|) is always positive

that means -6x always has to be positive

and for -6x to be positive x has to be negative

(since, two negatives make a positive)

therefore, the value of x to the equation will be a negative value and not a positive one.

Ana thinks both positive and negative values of x will be the solution, whereas Ling thinks negative value of x can't be a solution. So, they're both wrong.

ONLY negative value of x will be the solution.

(a) Draw a secant line on the graph above from x = 0 to x = 4. (copy the graph if you are writing your answers on a separate paper)

(b) What is the average rate of change of f (x) from x = 0 to x = 4? Show how you get your answer.

Answers

Answer:

Step-by-step explanation:

a. To draw a secant line, just draw a straight line connecting the 2 points at x = 0 and x = 4.

b. The average rate of change of this line is going to be the change in y / the change in x. The equation will be (f(4) - f(0))/(4 - 0) = (0 - 3) / 4 = -3/4.

compare the expressions
3 X 10 and 15 x 20 without multiplying them. Explain how she
could compare the factors to compare the expressions without
multiplying them.

Answers

Answer:

yes

Step-by-step explanation:

Well 3 is a factor of 15, and 10 a factor of 20. So 15/3 is 5, and 20/10 is 2.

5*2 is 10, which means that 15*20 is 10 times greater than 3*10.

If you actually did multiply them, 15 by 20 is 300 and 3 by 10 is 30. It would logically be correct.

Steven uses a
caliper that has an absolute error of 0.02 millimeters. An object's width is measured
using the caliper, which records a width of 14.5 millimeters. What equation would represent the situation?

A. |x-0.02|=14.5
B. |x-14.5|=0.02
C. |0.02-x|=14.5
D. |14.5-0.02|=x

Answers

The relationship between the measured value, error and actual width of the object is |x - 14.5| = 0.02

The measurement error = 0.02 millimeters The measured width of caliper = 14.5 millimeters

If the actual width of the caliper is represented as x

The measurement error is an absolute value which can be calculated thus :

|Actual value - measured value| = absolute error

|x - 14.5| = 0.02

Therefore, the equation which represents the scenario described is |x - 14.5| = 0.02

he product of two whole numbers is 864 and their sum is 60 . What are the two numbers?

Answers

Answer:

Step-by-step explanation:

xy = 864

x + y = 60                     Solve for y in the second equation

y = 60 - x                      

x * (60 - x) = 864          Remove the brackets.

60x - x^2 = 864           Put in order of powers and subtract 864

-x^2 + 60x - 864 =0    Multiply through by -1

x^2 - 60x + 864 = 0

This factors

(x - 36)(x - 24) = 0

Either

x - 36 = 0    in which case

x = 36

or

x - 24 = 0

x = 24

The two numbers are x = 36 and y = 24

of x = 24 and y = 36

whats 4(-2-9.2x)=3(2-7.6x) solve for x

Answers

Answer:

x = -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

[tex](4)(-2) + (4)(-9.2x)=(3)(2)+(3)(-7.6x)[/tex] [tex]-8 - 36.8x = 6 - 22.8x[/tex] [tex]-36.8x - 8 = -22.8x + 6[/tex]

Step 2: Add 22.8x to both sides.

[tex]-36.8x - 8 + 22.8x = -22.8x + 6 + 22.8x[/tex] [tex]-14x - 8 = 6[/tex]

Step 3: Add 8 to both sides.

[tex]-14x - 8 + 8 = 6 + 8[/tex] [tex]-14x = 14[/tex]

Step 4: Divide both sides by -14.

[tex]\frac{-14x}{-14}=\frac{14}{-14}[/tex] [tex]x = -1[/tex]

Therefore, x = -1.

The solution to the equation 4( -2 - 9.2x ) = 3( 2 - 7.6x ) is x = -1.

What is the solution to the equation?

Given the equation in the question:

4( -2 - 9.2x ) = 3( 2 - 7.6x )

To solve the equation 4(-2 - 9.2x) = 3(2 - 7.6x), distribute the constants and then isolate the variable x:

4( -2 - 9.2x ) = 3( 2 - 7.6x )

4 × -2 + 4 × -9.2x  = 3( 2 - 7.6x )

-8 - 36.8x = 3( 2 - 7.6x )

-8 - 36.8x = 3 × 2 + 3 × -7.6x

-8 - 36.8x = 6 - 22.8x

Collect like terms:

-8 = 6 - 22.8x + 36.8x

-8 - 6 = - 22.8x + 36.8x

Add like terms:

-14 = 14x

14x = -14

Divide both sides by 14:

x = -14/14

x = -1

Therefore, the value of x is -1.

A line with a slope of -3 passes through (-8,p) and (2,3p).
Find the value of p.

Answers

(3p-p)/(2-(-8))= -3

2p/10= -3

2p= -30

p= -15

Answer:

-15

Step-by-step explanation:

Given that a line has a slope of -3 and passes through the points (-8,p) and (2,3p) . And we need to find out the value of p . As we know that the slope is ,

[tex]\longrightarrow\sf slope = y_2-y_1/x_2-x_1[/tex]

Substituting the respective values ,

[tex]\longrightarrow[/tex] -3 = (p - 3p)/(-8-2)

Simplify ,

[tex]\longrightarrow[/tex] -3 = -2p/-10

[tex]\longrightarrow[/tex] -3 = p/5

[tex]\longrightarrow[/tex] p = 5 * -3

[tex]\longrightarrow[/tex] p = -15

Hence the value of p is -15 .

The tallest living man at one time had a height of 224 cm. The shortest living man at that time had a height of 97.8 cm. Heights of men at that time had a mean of 174.21 cm and a standard deviation of 5.56 cm. Which of these two men had the height that was more​ extreme?

Answers

Answer:

the shorter man

Step-by-step explanation:

224 cm minus 174.21 = 49.79

49.79/5.56= approximately 9 standard deviations from the mean.

174.21 minus 97.8= 76.41

76.41/5.56= approximately 14 standard deviations from the mean.

bc the shorter man's height is more SD's away from the mean (average) height his height difference is more extreme.
