For the first 3 images.

a) The linear equation is the  one in option A:

y = x

b) The linear equation is the one in option B:

y = (1/2)*x + 3

c) The correct option is C, the slope of scenario 1 is 60

A general linear equation is:

y = a*x + b

So we have a polynomial of degree 1, this means that there can be at most two terms, one that depends of x, and other that is a constant.

From the first list the only linear equation is y = x.

none of the others depend linearly with x.

From the second list the only option that is a linear equation is B.

y = (1/2)*x + 3

Where you can see two terms, the first one depends linearly of x and the second one is a constant.

For the third image.

If you evaluate the equation for scenario 2 in x = 1, you get:

y = 50*1 = 50

So in one hour, you travel 50 miles.

While on scenario 1, on one hour you travel 60 miles.

Then the speed is greater on scenario 1, where the slope is 60, so the correct option is C.

The percentage she spends on books from her total edducational expenses is 0.17

What is Percentage?

A percentage is a fraction of a whole represented as a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent. To calculate a percentage, divide the share of the total by the total and multiply by 100.

Solution:

Assuming there are only these two expenses on education,

the total expenses are 1100 + 225 = $1325

amount the student pays on books = $225

Percentage = (225/1325) * 100

Percentage = 16.98% = 17% (approx)

So, the final answer is 0.17

Miguel has a higher unit rate of change than Donna because 53mph is greater than 48mph.

The unit rate is used to show the relationship between the variables illustrated. Since Miguel drove for 8 hours at a constant rate and drove a total of 424 miles. The rate will be:

= 424 / 8

= 53 miles per hour.

The unit rate for Donna will be:

Miles / Time

Answer:

  A. The number of pages in the assignment

Step-by-step explanation:

You want to know which of several possibilities the amount of time it takes to complete a reading assignment might be a function of: pages, cost, age of the book.

We expect that an assignment to read more pages will result in a longer completion time. While there might be different completion times for the same number of pages in different assignments (relation not a function), the relation might be a function for assignments in the same book.

There are many factors affecting the cost of a book, including the materials it is made of, the number of printed copies, the difficulty of providing the necessary typesetting and illustrations. These factors may also affect the time it takes to read an assignment. In general, we don't expect that a given number of pages in a book costing $20 will take longer to read than in a book costing $10 or $50. That is, we don't expect completion time to be a function of the cost of the book.

As with book cost, the year of publication may also have a relationship with readability. Older books may use different language, unfamiliar terminology, more (or less) complex illustrations, different typography. These may have a bearing on the time it takes to complete a reading assignment. However, if the same material is presented in the same way in a book published in 1900 versus 2000, we don't expect the assignment completion time to change.

The time it takes to complete a reading assignment is most likely to be a function of the number of pages in the assignment (other factors being equal).

The interest rate is 6%.

What is an interest rate?

The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate. The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.

Here,

It is given the initial amount was $1100 and after 51  days, it was worth $1110.44.

The interest can be calculated as follows:

Interest = $1110.44 - $1100

= $ 10.44

Now, we find the simple interest

I = PRT

I =  10.44

P =  $1100

T = 51 days

R =?

We put the given value in the formula and get

10.44 = (1100 ×51 ×R)/360

R = 0.066 × 100%

R = 6%

Hence, the interest rate is 6%.

The options that are partial products for 43 × 17 include:

B. 21

E. 400

We want to find the partial products of 43 x 17

Since 43 = 40 + 3

and 17 = 10 + 7

Then

43 x 17 = (40 + 3) x (10 + 7)

We find all the partial products by multiplying one term of the first addition with one term of the second:

43 x 17 = (40 + 3) x (10 + 7)

= (40 x 10) + (40 x 7) + (3 x 10) + (3 x 7)

The scenario with the greater speed is scenario 1, then the correct option is C

"Scenario 1 because the slope is 60"

Remember that speed is defined by:

distance = speed*time

On scenario 2 we have the linear equation:

y = 50*x

Where y is distance and x is the time in hours, so the speed is 50 miles per hour.

If we look at the graph, we can see a proportional relationship also of the form y = k*x

Where the slope k is the speed.

The first graphed point is (1, 60), then:

60 = k*1

60/1 = k

So here the speed is 60 miles per hour.

Step-by-step explanation:

If 5y-1=x

then you can substitute x into the first equation

x-4y=-8

as we know x=5y-1 then

(5y-1)-4y=-8 is true

5y-4y is just y

so we are left with y-1=-8

add 1 to both sides

y=-7

substitute this into other equation

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A lawyer charges a proper expense for an underlying gathering and an hourly charge for the entire hours worked after this gathering. She charges $1750 for an underlying gathering and $300 consistently worked.

Let 'x' be the number of hours and 'y' be the total cost. Then the equation is given as,

y = 300x + 1750

The total cost after 1 hour of work will be

y = 300 (1) + 1,750

y = 2,050

The total cost after 20 hours of work will be

y = 300 (20) + 1,750

y = 7,750

The equation is y = 300x + 1,750. And the total cost after 1 hour and 20 hours of work will be $2,050 and $7,750, respectively.
