Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).

Mathematics

sattari [20]3 years ago

Answer:

y + 9 = \frac{1}{5}(x + 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = \frac{1}{5} and (a, b) = (- 4, - 9) , thus

y - (- 9) = \frac{1}{5}(x - (- 4) ) , that is

y + 9 = \frac{1}{5}(x + 4)

An outside thermometer reads -4 degrees at 7:00 a.m. By 2:30 p.m. the temperature outside has increased by 11 degrees. At 2:30 p
Gnesinka [82]

Answer:

-169 degrees

Step-by-step explanation:

It doesn't make much sense... but let's answer the question anyway.

First task is to determine what's the temperature outside at 2:30 PM.

We know that it's 11 degrees cooler than it was at 7 AM, so -4 - 11 = -15 degrees.

Abram's house is 4 degrees less than 11 times the outside temperature, so we can express that as:

House = 11 x - 4    - where x is the temperature outside.

If we replace the numbers we get: 11 * (-15) - 4 = -165 - 4 = -169 degrees

Abram's house is an extremely cold freezer!

Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat.
skad [1K]

Correct answer is 200(25)(\frac{1}{3})  or , 200×25÷3 . Given answer is not in any of option! kindly match this answer with your options available!

<u>Step-by-step explanation:</u>

Here we have , Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats. We need to find Which expression shows a correct way to find  how many yards of rope he needs. Let's find out:

Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat , i.e. for 1 doormat he uses 200 feet of rope

⇒ 1 Doormat=200 ft

So , for 25 Doormat he uses :

⇒ 25(1 Doormat)=25(200) ft

⇒ 25 Doormat=25(200) ft

But , 1 yard = 3 ft ⇒ 1 feet = \frac{1}{3} yard  .Hence ,

⇒ 25 Doormat=25(200) (\frac{1}{3})yards

Hence Correct answer is 200(25)(\frac{1}{3})  or , 200×25÷3 . Given answer is not in any of option! kindly match this answer with your options available!

Two hockey teams, the Winnipeg Jets (yay!) and the Toronto Maple Leafs (boo!), miraculously make it to
monitta

Answer:

There is a 54% chance that the Jets will win the Stanley Cup.

Step-by-step explanation:

Since two hockey teams, the Winnipeg Jets and the Toronto Maple Leafs, miraculously make it to the Stanley Cup finals, where as soon as a team wins 3 games, the championship is over, and the schedule for the playoffs for home games is: Jets - Leafs - Jets - Leafs - Jets; since if the Jets are playing at home, there is a 60% chance they'll win, while if they are playing on the road, there is a 45% chance they'll win, to find the probability that the Jets win the Stanley Cup the following calculation must be performed:

(0.60 + 0.45 + 0.60 + 0.45 + 0.60) / 5 = X

2.70 / 5 = X

0.54 = X

Thus, there is a 54% chance that the Jets will win the Stanley Cup.
