Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100  

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase

Answer:

<u>Problem 4:</u>  Option C, 32

<u>Problem 5:</u>  You need to have the 2 and the x combine.  Make the table 2x than 16.

<u>Problem 6:</u>  x = 17

<u>Problem 7:</u>  She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Step-by-step explanation:

<u>Problem 4</u>

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

Answer:  Option C, 32

<u>Problem 5</u>

You need to have the 2 and the x combine.  Make the table 2x than 16.

Answer:  You need to have the 2 and the x combine.  Make the table 2x than 16.

<u>Problem 6</u>

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

Answer:  x = 17

<u>Problem 7</u>

She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Answer: She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Please help me with these 5 questions!
kipiarov [429]

Answer:

Part 2) Option D. yes; k = 1/4 and y = 1/4x

Part 6) Option D. y = 1/5x-1

Part 8) Option C. line b

Part 11) Option D. -1/5

Part 15) Option A. line a

Step-by-step explanation:

Part 2) we know that

A relationship between two variables, x, and y, represent a directly variation if it can be expressed in the form  y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Yes. y varies directly with x

Let

A(4,1)

The constant k is equal to

k=y/x

substitute

k=1/4

the equation is equal to

y=(1/4)x

Part 6) we know that

The y-intercept of the trend line is -1 (For x=0)

The slope of the trend line is positive

The x-intercept of the trend line is 5 (For y=0)

therefore

the equation is equal to

y=(1/5)x-1

Part 8) we have

y+4=-\frac{2}{3}x

This is the equation of a line into point slope form

The slope is negative m=-2/3

Pass through the point (0,-4) ----> y-intercept

The x-intercept is equal to

0+4=-\frac{2}{3}x

x=-4*3/2=-6

therefore

Is the line b

Part 11)

What is the slope of the line through the points (–2, –1) and (8, –3)?

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-3+1}{8+2}

m=\frac{-2}{10}

simplify

m=-\frac{1}{5}

Part 15) we have

y=3x-2

The slope is positive m=3

The y-intercept is -2 (For x=0)

The x-intercept is  (For y=0)

0=3x-2

3x=2

x=2/3

therefore the line is a
