What is the equation to a line with a slope of -3 and a y-intercept of 8?

Answers

Answer:

y=-3x+8

Step-by-step explanation:

y=mx+b

(m=slope and b=y-intercept)

Answer:

Step-by-step explanation:

let’s use this equation y = mx + b

where m = slope

and b = y intercept

since slope is -3, m = -3

and since y intercept is 8, b = 8

so the equation is

y = -3x +8

what two numbers' sum=-4 and product=-2

Answers

Let a and b be the two numbers. Then

a + b = -4

a b = -2

Solve the second equation for b :

b = -2/a

Substitute this into the first equation:

a - 2/a = -4

Multiply both sides by a :

a² - 2 = -4a

Move 4a to the left side:

a² + 4a - 2 = 0

Use the quadratic formula to solve for a :

a = (-4 ± √(4² - 4(-2))) / 2

a = -2 ± √6

If a = -2 + √6, then

-2 + √6 + b = -4

b = -2 - √6

In the other case, we end up with the same numbers, but a and b are swapped.

Dr yang buys a violin for £13200 plus vat at 20% dr yang pays a deposit for the violin he then pays the rest of the cost in 12 equal payments of £360 each month find the ratio of the deposit dr yang pays to the total of the 12 equal payments give your answer in its simplest form

Answers

Answer:

8/3

Step-by-step explanation:

Given that:

Cost of violin = 13200 plus VAT at 20%

Cost of violin = (100 + 20)% * 13200

Cost of violin = 1.20 * 13200 = £15,840

Instalment pay = (360 * 12) = 4320

Therefore, deposit made equals ;

Total cost - Instalment pay

£(15,840 - 4320) = £11,520

Hence, ratio of deposit made to the total Instalment payment made ;

£11520 / £4320 = 8 / 3

The slope of the line below is 2. Which of the following is the point-slope form of the line?​

Answers

The correct point-slope form of the line is A. y + 1 = 2(x - 1).

The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.

Given that the slope of the line is 2 and the point on the line is (1, -1), we can substitute these values into the point-slope form to find the correct equation.

Using the point-slope form, we have:

y - (-1) = 2(x - 1)

Simplifying the equation, we get:

y + 1 = 2(x - 1)

Now we compare this equation to the answer choices:

A. y + 1 = 2(x - 1)

B. y - 1 = -2(x + 1)

C. y + 1 = -2(x - 1)

D. y - 1 = 2(x + 1)

Comparing the equation y + 1 = 2(x - 1) to the given point-slope form, we see that they match.

In this equation, the point (1, -1) lies on the line, and the slope of the line is 2. The equation represents a line with a slope of 2 that passes through the point (1, -1).

James is earning money to buy a bicycle for $100. For each dollar James earns, his mother gives him $1. So far he has earned $14 mowing lawns and $7 wash cars. How much more must James earn in order to but the bike??

Answers

Answer:

James needs to earn 78 more dollars.

Step-by-step explanation:

If you add up all of the money James has earned, (1 + 7 + 14), it equals 22. If you subtract 22 from 100, it equals 78. Therefore James needs to earn 78 more dollars.

Answer:

$58

Step-by-step explanation:

$14*2=$28 as her mum gives another dollar for each dollar he earns

$7*2=$14  as her mum gives another dollar for each dollar he earns

then 28 + 14 = 42

100 - 42=$58

A video posted on the internet is becoming very popular, and the total number of views is increasing by 40% every hour. If the video currently has 74,300 views, how many views will it have in 9 hours?

Answers

Answer:

74304 approx.

Step-by-step explanation:

Step one:

given data

current view of the video is marked at =74300

the rate of increase is 40%

let the number of hours be x

and let the total views be y

hence the linear function for the total is

y=0.4x+74300

Required is the value of y when  x=9

Step two:

substitute x=9

y=0.4(9)+74300

y=3.6+74300

y=74303.6

y=74304 approx.

Step-by-step explanation:

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

Then f(x - 2) represents a shift to the right of 2 units

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Then f(x - 2) + 3 is shift to the right of 2 and up by 3 units
