Which equation represents a line that has a slope of One-third and passes through point (–2, 1)?
y = one-third x minus 1
y = one-third x + five-thirds
y = one-third x minus five-thirds

Answer: 60%

Step-by-step explanation:

(5 × p) / 100 = 3

((5 × p) / 100) × 100 = 3 × 100

5p = 300

5p / 5 = 300 / 5

p = 60

Percent Increase = 60

The equations that represent the left side, right side, top side and bottom side are y = 3x+2, y = 3x-10, y = 5 and y = -1 respectively

The slope-intercept form of the equation of a line is y =mx+c,

where m is the slope and c is the y-intercept

slope(m) = y2-y1 / x2-x1

Left side

The line moves from point 1 (-1, -1) to point 2 (1,5)

x1 = -1, y1 = -1 and x2 = 1, y2 = 5

Slope(m) = 5-(-1) / 1-(-1)  = 6/2 = 3

Using the equation of a line for 2 points:

y-y1 = m(x-x1)

y-(-1) = 3(x-(-1))

y+1 = 3(x+1)

y+1 = 3x+3

y = 3x+2

Right side

The line moves from point 1 (3, -1) to point 2 (5,5)

Slope(m) = 5-(-1) / 5-3  = 6/2 = 3

y-(-1) = 3(x-3)

y+1 = 3x -9

y = 3x-10

Top side

y = 5

Bottom side

y = -1

Therefore, equation for the left side : y = 3x+2, equation for the right side: y = 3x-10, equation for the top side: y = 5 and equation for the bottom side: y = -1

The monthly installment to be paid is $17.85.

Given:

A washing machine is priced at $450. A man buys the washing machine on HP according to the following terms: A deposit of 15% and the remaining to be paid in monthly installment over 2 years at a simple interest rate of  12 % per annum.

Remaining amount = 450 - 450*15/100

= 450 - 9*15/2

= 450 - 67.5

Answer:

B. 1 over 3 x 12 hours

Step-by-step explanation:

The oil company fills 1/12 of a tank in 1/3 an hour. So, you multiply 1/3 times 12, since 12 is a full tank. It'll take 4 hours to fill the tank at this rate.

1/12 tank: 1/3 hour

2/12 tank: 2/3 hour

3/12 tank: Full hour

3/12 is equivalent to 1/4, meaning 1/4 of the tank is filled after 1 hour. Thus, it'll take 4 hours.

y=-x+16

Step-by-step explanation:

let’s put this equation in slope intercept form: y=mx+b

2x+2y=-8

-2x.      -2x

2y=-2x-8

/2.  /2.  /2

y=-x-4

We know parallel lines have the same slope as each other so let’s fill in the equation with the given point

10=-(6)-4

10=-10

We need to add 20 more to the y intercept to make this true like this

y=-x-4+20

y=-x+16

Now let’s see if it works

10=-(6)+16

10=10

It works so this is the equation

Hopes this helps please mark brainliest

Answer: y = -x +16

Step-by-step explanation:

rearrange the equation to make y the subject

2y = -2x -8

y = -x-4

equation of line parallel to the line (gradient will be the same)

y = -x +c

Substitute the x and y values into the parallel line equation

10 = -6 + c

10 + 6 = c

16 = c

Therefore, the equation of the line parallel to 2x + 2y = -8 is y = -x +16

The slope of a line that is parallel to the line y = x + 2 is 1.

What is slope?

A line's steepness is determined by its slope. In mathematics, the slope is determined by "rise over run" (change in y divided by change in x).

Given the equation of line: y = x + 2

We have to find the slope of a line that is parallel to the given line.

Since any line parallel to the given line  y = x + 2  will have the same slope as that of a given line

The general equation of line is given as y = mx + c

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

Thus for given equation of line y = x + 2

Comparing , we get

slope is m=1

Thus, any line with slope 1  is parallel to the given line y = x + 2

Now the value of x will be,

→ 8x + 16 = 2x + 16

Hence, the value of x is 0.

The smallest number of people when one could have been at the party is 211 people.

This is a least common multiple question, also known as an LCM. We know this because all groups would have formed evenly if the one extra person had not arrived at the party. This means that there are 1 more people at the party than a number 2, 3, 5, or 7.

In this case, the number will be:

= (2 × 3 × 5 × 7) + 1

= 210 + 1

= 211

Applicable multiples of 7

(7 × 10) = 70 → 70 + 1 = 71 → 71/3 = 23 R2 → not possible

(7 × 20) = 140 → 140 + 1 = 141 → 141/3 = 47 → not possible

Answer: 0.555555556

Step-by-step explanation:

15/27=0.555555556

Checking work by plugging it in: 27x0.555555556=15

======================================================

Work Shown:

a = old value = 15

b = new value = 27

c = change in values

c = b-a

c = 27-15

c = 12

The positive c value tells us that we have an increase.

Then divide over the starting value a = 15

c/a = 12/15 = 0.80

Move the decimal point two spots to the right to go from 0.80 to 80%

Or multiply 0.80 with 100% to get 0.80*100% = 80%

We have a percent increase of 80%

-------------------

Check:

80% of 15 = 0.80*15 = 12

If the stock increases by 80%, then it has increased by $12 to go from $15 a share to 15+12 = 27 dollars a share. This confirms the answer.

A slight shortcut would be to say 1.80*15 = 27

The multiplier 1.80 represents an increase of 80% since 100% + 80% = 1 + 0.80 = 1.80

As per the concept of counting problem, the reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.

Counting Problems

Basically, counting refers the process of finding the number of elements of a finite set of objects.

Given,

Suppose you have a nickel, two dimes, and a quarter. One of the dimes was minted in 1976, and the other one was minted in 1992.

While we looking into the given problem,

For A) states that,  If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins. Let us label the dime as D, the penny as P, the quarter minted in 1976 as Q1 and the quarter minted in 1992 as Q2.

Here in this process if you choose one coin, you could choose either D, P, Q1, or Q2. This gives us 4 possible sets.

And If you choose two coins, you choose the following sets of coins: DP, DQ1, DQ2, PQ1, PQ2, Q1Q2. This gives us 6 possible sets.

Then If you choose three coins, you could the following sets of coins: DPQ1, DPQ2, DQ1Q2, PQ1Q2. This gives us 4 possible sets.

So, If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible set.

So, the total number of different sets of coins you can form is 4 + 6 + 4 + 1 = 15 different sets of coins can be formed.

Similarly, for b) If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins.

Then If you choose one coin you could choose either D, P, Q1, or Q2. However, since Q1 and Q2 give us the same sum, they are effectively the same set. This gives us 3 possible sums.

So, If you choose two coins, you could choose the following sets of coins : DP, DQ, PQ, Q1Q2.And this gives us 4 possible sums

Then If you choose three coins, you could choose the following sets of coins: DPQ, DQ1Q2, PQ1Q2. And this gives us 3 possible sums

Then If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible sum.

So, the total number of different sums of coins you can form is 3 + 4 + 3 + 1 = 11 different sums of money can be produced.

Finally, c) The reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.
