Answer:
4) yes, the rate is 3
5) no
6) yes, the rate is 5
Step-by-step explanation:
Direct variation is y = kx.
4.
First, substitute your values into the equation for direct variation to find K, the rate.
3 = k(1)
3 = k
Now let's see if this holds true.
6 = 3(2)
6 = 6
This looks true, but let's do another one from the table.
9 = 3(3)
9 = 9
And another just to check.
12 = 3(4)
12 = 12
So, #4 is direct variation.
5.
1 = k(2)
1/2 = k
Let's test for all of the other values to be sure.
2 = (1/2)(3)
2 ≠ 1.5
3 = (1/2)(4)
3 ≠ 2
This is not true. #5 is not an example of direct variation.
6.
5 = k(1)
5 = k
Time to check.
10 = 5(2)
10 = 10
Again.
15 = 5(3)
15 = 15
Again.
20 = 5(4)
20 = 20
One last time...
25 = 5(5)
25 = 25
#6 is an example of direct variation.

Edward paid $4.77 in sales tax on an item that cost $53.00 before tax. At that rate, how much would he pay in sales tax for an item that costs $61.00 before tax?
Answers
Answer:
He would pay $5.49
Step-by-step explanation:
edward would pay $5.49 on sales tax for an item that costs $61.00.
net price: $61.00
sales tax rate: 9.00%
the formula for finding sales tax is sales tax amount = net price x (sales tax percentage / 100).
total price = net price + sales tax amount.
so,
$61.00 x (9 / 100) = $5.49
total = $61.00 + $5.49 = $66.49
because this question is not asking for the total price, we can dismiss that.
input $5.49 as your answer. you've then completed this question.
if you have any confusion, please reach out to me and i'll try to help you as best as i can :).

The better estimate of the number division is 700 ÷ 7 = 100 and it is an over estimate
How to carry out number division?In division, we divide a number by any other number to get another number as a result.
The number which is getting divided here is called the dividend.
The number which divides a given number is the divisor.
The number which we get as a result is known as the quotient.
We want to divide: 678 ÷ 7
This gives us: 96 remainder 6
Looking at the options:
630 ÷ 7 = 90
700 ÷ 7 = 100
The initial answer could be approximated to 100 and so 700 ÷ 7 = 100 is a better estimate

Explain the placement of the decimal point when dividing by a power of 10.
Answers
Answer:
You end up moving each digit in the number one place to the right.
Step-by-step explanation:
move all digits in the ones place to the right.
like for example: 31÷10
The 1 moves to the tenths column making that 3.1
If that makes sense :)
The power of ten is a bit more you will count the zeros in the divisor (number by another number that is divided) then move the decimal in the dividend (portion) to the left.
Maybe this will help ¯\_(ツ)_/¯
srry if this ends up making no sense, it is quite hard to explain and confusing.
:)
Answer:
We know that the decimal point goes to the right of the ones place. So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. ... So if you divided a number by one hundred (10^2 or 10*10), you would move two places to the left.

Answers
Answer:
Unit Price= $1.18
The error is that the contractor divided $99.12 by 7 and didn't multiply the 7 by the dozen (12) first, which lead to a mistake.
Step-by-step explanation:
To find the unit price:
1) multiply 7x12 = 84

What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?
2 x + y - 8 = 0
x + 2 y - 8 = 0
2 x - y + 8 = 0
Answers
Answer:
The first one plz brainliest
Step-by-step explanation:
2x + y - 8 =0
- 2x from both sides
Y - 8 = -2x
Then add 8 to both sides
Y = -2x + 8
The second one = -1/2x + 4 when its in slope intercept form
And the third one = y = 2x + 2
So it’s the first equation that ve slope of -2 and y intercept of 8
