Step-by-step explanation:

y=mx+b

5y=10x-15   dived all by 5

y=2x-3----------2 is the slope

y=mx+b

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

x - y = 1 ( add y to both sides )

x = y + 1 ( subtract 1 from both sides )

x - 1 = y , that is

y = x - 1 ← in slope- intercept form

Answer:

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Step-by-step explanation:

Hamish and Harry work as plumbers. Harry earns a dollar more than 5/4 the amount Hamish earns per hour. The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour. How much does each of them earn per hour?

Hamish earnings per hour = x

Harry earnings = 1 + 5/4x

The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour

Harry also earns = 7/5x - 2

Equate both Harry's earnings

1 + 5/4x = 7/5x - 2

Collect like terms

1 + 2 = 7/5x - 5/4x

3 = 28x-25x/20

3 = 3/20x

Divide both sides by 3/20

x = 3 ÷ 3/20

= 3 × 20/3

x = 20

Hamish earnings per hour = x

= $20

Substitute Harry's earnings into 7/5x - 2

= 7/5 × 20 - 2

= 28 - 2

= 26

Harry's earnings = $26

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Answer:

68.268%.

Step-by-step explanation:

Let \mu be the mean pregnancy length.

The given standard deviation, [tex]\sigma=7[/tex] days

The z-score:

z=\frac{x-\mu}{\sigma}

where x is any pregnancy length.

The range of x within 7 days of the mean pregnancy length is

[tex]\mu-7<x<\mu+7.[/tex]

z-score for this range is:

[tex]\frac{\mu-7-\mu}{\sigma}<z<\frac{\mu+7-\mu}{\sigma}[/tex]

[tex]\Rightarrow -1<z<1[/tex]

So, the area on the normally distributed curve for the above range of z-score will give the expected percentage of birds to occur within 7 days of the mean pregnancy length.

Now, from the z-score table:

The area from [tex]z = -\infty[/tex] to z=1 is 0.84134

and the area from [tex]z = -\infty[/tex] to z=-1 is 0.15866.

So, the area for -1<z<1

=0.84134 - 0.15866

=0.68268

Hence, the percentage of births would be expected to occur within 7 days of the mean pregnancy length=68.268%.

Answer:

8.50 divided by 1.25 then when u get the answer subtract 40

Answer:

25

Step-by-step explanation:

so instantly 40-8.50=31.5

The question is very vague because it doesn't state the number of rides he wants to go on in minimum.

if you do 1.25x25=31.25

According to that, he will leave with a change of 0.25 and obv u cannot go on half a ride...

So in about 2 mins i guess it is 25???

Answer:

The dimensions that result in the maximum area are therefore;

Width = 3.5

Height = 3.5

Step-by-step explanation:

The given parameters are;

The area of the rectangle, y = x × h

Where;

x = The width of the rectangle

h = The height of the rectangle

By examination, we have;

x + h = 7

Therefore, x = 7 - h

Which gives;

y = x × (x - 7) = x² - 7·x

y = x² - 7·x

At x = 0, y = 0

At x = 7, y = 0

However, at x = 1, y = -6

Therefore, the function should be, y = -(x² - 7·x)

The maximum occurs where dy/dx = 0, which gives;

dy/dx = d-(x² - 7·x)/dx = 0

dy/dx = 2·x - 7 = 0

2·x - 7 = 0

x = 7/2 = 3.5

On second derivative, we have;

d²y/dx² = 2, which gives a local minimum

x = 3.5 at maximum height

Which give, the maximum height, [tex]y_{max}[/tex] = -(x² - 7·x) at x = 3.5

∴ [tex]y_{max}[/tex] = -(3.5² - 7×3.5) = 12.25

The maximum height = 12.25

The dimensions that result in the maximum area are therefore;

Width, x = 3.5

Height, h = 7 - x = 7 - 3.5 = 3.5

Height, h = 3.5.

Step-by-step explanation:

Answer:

The difference is 3.97 inches of rainfall

Step-by-step explanation:

Here, we want the difference between the wettest and driest months.

From the question, we can see that the wettest month has a rainfall height of 2.3 inches

The driest month has a rainfall of -1.67 inches

So the difference between the two will be;

2.3 - (-1.67)

= 2.3 + 1.67 = 3.97 inches

Answer:

4.03

Step-by-step explanation:

Have to add 2.36 and 1.67 and it would be a positive.

D)y=5x³ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌

Answer:

y = 5x^3

If there is an exponent other than 1 on a variable, then it is not linear.

Answer: y = 5x^3 since the exponent on x is 3.

Answer:

She used an average of (115/30) gigabytes of data per day

Step-by-step explanation:

To get the average data usage per day, we simply divide the total data used by the number of days

Mathematically, that will be

115 gigabytes/ 30 days = 3.83 gigabytes per day

Answer:

5 adults went on the trip.

Step-by-step explanation:

There are 14 children ($75 each) and the total was $1475. We need to find out how many adults were there ($85 each)

c is for children and a is for adults

equation:  $75c+ $85a = $1475

$75(14)+ $85a= $1475

$1050 + $85a = $1475

-1050                   -1050

$85a = $425

85a/85 = 425/85

a = 5

5 adults went on the trip. Hope this helps! :)

There were 5 adults that went on the trip.

Unitary method is finding the value for a single unit.

According to the given question During spring break, a class of 14 children went to Walt Disney World in Florida the price for each child’s ticket was 75 dollars.

So, Cost of tickets of 14 children is

= (14 × 75) dollars.

= 1050 dollars.

Total amount spent on tickets for children and adults is 1475 dollars.

∴ Total amount spent for tickets for the adults is

= ( 1475 - 1050 ) dollars.

= 425 dollars.

Given price of one ticket for adult is 85 dollars, So for 425 dollars the no. of tickets will be

= 425/85 dollars.

= 5 tickets which states there were 5 adults.

The transformation y = 7f(x - 8) has two effects on the graph of the original function y = f(x): a horizontal shift to the right by 8 units and a vertical stretching by a factor of 7.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The transformation to the graph y = f(x) if it is transformed to y = 7f(x−8)

The horizontal shift to the right by 8 units means that each x-value in the original function is decreased by 8. This has the effect of shifting the entire graph of the function 8 units to the right along the x-axis.

The vertical stretching by a factor of 7 means that each y-value in the original function is multiplied by 7. This has the effect of stretching the entire graph of the function vertically by a factor of 7.

Together, these two effects cause the graph of the transformed function y = 7f(x - 8) to be a vertically stretched version of the original graph, shifted 8 units to the right along the x-axis.

The shape of the graph will remain the same, but it will be taller and shifted to the right compared to the original graph.
