Write an equation in point slope form for the given line

Mathematics
1 answer:
PtichkaEL [24]3 years ago
7 0

Answer:

\large\boxed{y-4=-\dfrac{1}{2}(x-1)}

Step-by-step explanation:

Look at the picture.

The formula of a slope:

The point-slope form of an equation of a linear function:

y-y_1=m(x-x_1)

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (1, 4) and (-3, 6). Substitute:

m=\dfrac{6-4}{-3-1}=\dfrac{2}{-4}=-\dfrac{1}{2}\\\\y-4=-\dfrac{1}{2}(x-1)

A.
the y intercept is where x=0
x represents the number of months
when the number of months is 0, that is the initial number of games won

that looks to be a little below y=2, so maybe y=1.8?
the y intercept is y≈1.8
it represents the number of games won with 0 months of practice



B.
we can use y=mx+b
m=slope
b=y intercept
we know the y intercept
find the slope
slope=rise/run
the I'm going from x=0 to x=10
the rise is about 18.95 (from 1.8 to 20.75)
the run is 10
so slope would be 18.95/10=1.895

the equation would be y=1.895x+1.8
the points were (0,1.8) and (10,20.75)

Twelve round gold medals each with a radius of three inches just fit inside a box with four medals in each of the three rows a r
Anna35 [415]

Answer: The answer is 84 inches.


Step-by-step explanation:  It is given that twelve round gold medals fit inside a box where 4 medals are placed in one ray. So, the number of rows in the box is 3.

The radius of each gold medal = 3 inches.

Therefore, diameter of each gold medal = 2 × 3 = 6 inches.

The box is obviously in the rectangular form where

\textup{length} = 6\times 4=24~\textup{inches}\\\textup{and}\\\textup{Breadth}=6\times 3=18~\textup{inches}.

The red tape fits snugly around the sides of the box, so it will cover whole of the box.

Therefore, the length of the tape = 24+18+24+18 = 84 inches.

The sum of three numbers is 57
Katarina [22]
The first number is 15. The 2nd number is 30 cuz it’s double the first. The third number is 18 less than 30 so it is 12. They all add up to 57. Third # = 12
