Treat (a, 9) as an x and y value

Set the equation equal to 9

9= 2x+1
8= 2x subtract one
4= x divide by 2

a must be equal to four

Stickers are made with the same ratio of width to length. A sticker 2 inches wide has a length of 4 inches. Complete the table.
aalyn [17]

Answer:

The explanation of this question is given below in the explanation section

Step-by-step explanation:

The data is given in form of length and width.

Then, we need to convert it into improper fraction.

As you know that, the improper fraction is a fraction where the numerator (top number) is larger than the denominator (bottom number).

So, we converted it into improper fraction i.e.

Improper fraction= lenght/width

Then we reduce the fraction into lowest form and shown in ratio as depicted in attached picture with this solution.

Last question I'm stuck on now.
Yanka [14]

Answer:

This is kind of late, but I hope I could help maybe for a later assignment or assesment.

The estimates of y have become increasingly more precise, with some of the earlier ones having a margin of error of more than 0.8

None of the estimates support newton's theory that y=0

Most of the estimate support Einstein, or at least have a margin of error that accounts for einstien.

HELP PLZ GUYS I BEG YOU 15 PTS ITS EASYYYYYYY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Aliun [14]

Answer:

1) The linear equation in point and slope form is y - 67 = -4 × (x - 14)

2) The variables are;

a) The number of candies available = y

b) The number of days Jennifer eats the candies =

c) The slope, m = -4

3) Jennifer received 123 pieces of candies on Halloween

Step-by-step explanation:

The given parameters are;

The number of candies Jennifer eats everyday = 4 pieces

The number of days for which Jennifer eats the daily 4 candies = 14

The number of candies left at the end of the 14th day = 67 candies

1) We note that the rate of decrease in the number of candies = 4 candies/day

Therefore, the slope of the linear equation is m = -4

The y-intercept = The initial amount of candies Jennifer has = c = 67 + 14× 4 = 123 candies

The linear equation in point and slope form is given as follows;

y - 67 = -4 × (x - 14)

2) The variables are;

a) The y-value represents the number of candies available on a specific day

b) The x value represents the number of days Jennifer eats the candies'

c) The slope = The rate of decrease in the number of candies per day = -4

3) The number of candies Jennifer receives on Halloween is given by the y-intercept of the straight line equation as follows;

y - 67 = -4 × (x - 14)

y - 67 = -4·x + 56

y = -4·x + 56 + 67 = -4·x + 123

y = -4·x + 123

Comparing the above equation, with the general form of the straight line equation, y = m·x + c, where, the constant term, c = The y-intercept, we have;

The y-intercept of the equation y = -4·x + 123 = 123 = The initial amount of candies Jennifer received on Halloween.
