How to write a equation that passes through the points (-1,12) and (4,-8)

Mathematics

Answer:

y - 12 = (-4/5)(x + 1)

Step-by-step explanation:

Let's use the point-slope formula y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

1.  Find the slope.  As we go from (-1, 12) to (4, 8), x (the run) increases by 5 and y (the rise) decreases by 4.  Thus, the slope is m = rise/run = -4/5.

2.  Plug into the formula (given above) the following:

-4/5 for m, -1 for x and 12 for y:

y - 12 = (-4/5)(x + 1)

On Tuesday, Karen finished all her chores in 3/4 of an hour. On Wednesday, she finished her chores in 5/12 of an hour. How much
IRISSAK [1]
1 hour = 60 minutes

Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes

Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.

Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.

Hope this helps!

VARVARA [1.3K]

Answer:

6 samples

Step-by-step explanation:

Given :

Sample size, = n

Standard deviation, = 6000

Margin of Error = 2000

Confidence interval, α = 95%

Zcritical at 95% = 1.96

n = (Zcritical * σ) / margin of error

n = (1.96 * 6000) /2000

n = 11760 / 2000

n = 5.88

n = 6 samples
