The equation of a line is X+3Y=14
what is the y-intercept of the line?

Answers

X+3y=14
-x. -x
3y=-x+14
Divide them all by 3
Y=-x/3+14/3
Y-intercept= 1/3

Answer:  The required y-intercept of the given line is [tex]\dfrac{14}{3}.[/tex]  

Step-by-step explanation:  We are given to find the y-intercept of the following equation of a line :

[tex]x+3y=14~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

The slope-intercept form of the equation of a line is given by

[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.

From equation (i), we have

[tex]x+3y=14\\\\\Rightarrow 3y=-x+14\\\\\Rightarrow y=-\dfrac{1}{3}x+\dfrac{14}{3}.[/tex]

Comparing the above equation with the slope-intercept form, we get

[tex]\textup{y-intercept, c}=\dfrac{14}{3}.[/tex]

Thus, the required y-intercept of the given line is [tex]\dfrac{14}{3}.[/tex]

In the number 8,888.888, how does the 8 in the hundredths place compare to the 8 in the place to its left? A. The 8 in the hundredths place represents of what the 8 to its left represents. B. The 8 in the hundredths place represents of what the 8 to its left represents. C. The 8 in the hundredths place represents 100 times what the 8 to its left represents. D. The 8 in the hundredths place represents 10 times what the 8 to its left represents.

Answers

Final answer:

In the number 8,888.888, the 8 in the hundredths place is one-tenth of the value of the 8 in the tenths place, reflecting the structure of the decimal system where each place to the right of the decimal point is a tenth of the value of the position to its left.

Explanation:

When comparing the 8 in the hundredths place to the 8 in the tenths place (the place to its left), we need to remember that in our decimal numbering system, each place to the left is ten times greater than the place to its right. This is a fundamental property of the powers-of-ten notation, which our counting system is based on.

Therefore, the 8 in the hundredths place is one-tenth the value of the 8 in the tenths place. In other words, each 8 in the decimal part of the number 8,888.888 represents ten times less the value of the 8 to its immediate left. This reflects the structure of the decimal system, where each place to the right of the decimal point represents a fraction of 10 of the position to its left.

Multiply. 7x3/4 Enter your answer as an improper fraction, in simplified form.

Answers

[tex] \frac{7x3}{4} [/tex]

[tex] \frac{21}{4} [/tex]

The simplified form of fraction 21/4 is 3 4/7.

We have,

To multiply 7 by 3/4, you can multiply the numerator (7) by the numerator (3) and the denominator (4) by the denominator (1):

= 7 x 3 = 21 (numerator)

= 1  x 4 = 4 (denominator)

So, the result is 21/4.

However, we can simplify this improper fraction further.

Since 21 and 4 have a common factor of 7, we can divide both the numerator and denominator by 7:

21 ÷ 7 = 3 (numerator)

4 ÷ 7 = 4/7 (denominator)

Therefore,

The simplified form of fraction 21/4 is 3 4/7.

Tyler orders a meal that cost $15 if the tax rate is 6.6% how much will the sales tax be on Tyler's Meal?

Answers

Answer:

There would be $ 0.99 sales tax on the meal.

Step-by-step explanation:

Given,

The cost of the meal ordered by him = $15,

sales tax rate percentage = 6.6%,

Thus, the amount of the sales tax = 6.6% of the cost of the meal

= 6.6% of 15

[tex]=\frac{6.6\times 15}{100}[/tex]

[tex]= \frac{99}{100}[/tex]

[tex]= \$ 0.99[/tex]

The sales tax will be $0.99 on Tyler's meal.

How many times can 2 1/2 be subtracted from 12 1/2

Answers

2 1/2 = 2.5

This means you can calculate how may times it goes in by dividing it and rounding the number down:

12.5 / 2.5 = 5

*5 can not be rounded down so it stays the same

This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)

What is 24.678 rounded to two decimal places?

Rounding off to two decimal place means that you are rounding to the nearest hundredths. For this, you need to check whether the number next to the thousandth place is greater than 5, or lesser than 5, If its greater than 5, you need to round up. If its lesser than 5, you need to round down.

8 is sitting in the thousandth place, therefore, we will be adding+1 to the hundredth place.

In basketball some baskets worth two points others worth three points.in one game the ratio of three point baskets to three point tries for one team was 5:8 if team scored 60 points from three point baskets,how many three point tries did the team have?

Answers

5 actual baskets made and 8 3-point tries. The ratio is 5:8.
You can make a proportion as follows,
5/8=60/x
5 and 60 are equivalent since both are 3-point tries.
What times 5 will equal 60? 12.
So if you multiply 5*12 you will get 60. And if you multiply 8*12 you will get 96.
X=96.
The team tried 96 three-point baskets.
The team tried 96 three point baskets.
