creativ13 [48]3 years ago
3 0

Answer:

m=3/2

Step-by-step explanation:

The slope can be calculated using the following equation

m=\frac{y_{2}- y_{1} }{x_{2}- x_{1}}

Where

(x2,y2)=(4,-1)

(x1,y1)=(2,-4)

Amanda's school is due west of her house and due south of her friend Shereen's house. The distance between the school and Sheree
Blizzard [7]

The Amanda's house is 6.7 km far from her school.

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

From the given information,

  • The Amanda's school is due west of her house forms the base.
  • The school is due south of the Shereen's house forms the height.
  • The straight-line distance between Amanda's house and Shereen's house forms the hypotenuse.

Therefore, It can be determined that it forms the right angle triangle.

It is given that,

The distance between the school and Shereen's house is 2 kilometers.

That is, the height of the triangle = 2 km

The straight-line distance between Amanda's house and Shereen's house is 7 kilometers.

That is, the hypotenuse of the triangle = 7 km

Now, the distance between the Amanda's house and her school is the base of the triangle.

<u>To find the base :</u>

Base = \sqrt{(hypotenuse)^{2}-(height)^{2}  }

⇒ \sqrt{(7)^{2} -(2)^{2} }

⇒ \sqrt{49-4}

⇒ \sqrt{45}

⇒ 6.7 km

Therefore, the Amanda's house is 6.7 km far from her school.

Wolverine makes a $1000 down payment for a motorcycle and then pays $300 per month. James Bond makes a $2500 down payment for a
Delicious77 [7]

Answer:

Both Wolverine and James Bond will have paid the same amount after 10 months.

Step-by-step explanation:

Let x denotes the number of months after which both Wolverine and James Bond will have paid the same amount.

As Wolverine makes a $1000 down payment for a motorcycle and then pays $300 per month,

Amount paid by Wolverine in x months is equal to 1000+300x

As James Bond makes a $2500 down payment for a motorcycle and then pays $150 per month,

Amount paid by James Bond in x months is equal to 2500+150x

To find number of months after which both Wolverine and James Bond will have paid the same amount,

solve 1000+300x=2500+150x

1000+300x=2500+150x\\300x-150x=2500-1000\\150x=1500\\x=\frac{1500}{150}=10

So, both Wolverine and James Bond will have paid the same amount after 10 months.
