Answer:

-2/5

Step-by-step explanation:

Slope of a line is also called gradient.

Let A(x₁,y₁) and B(x₂,y₂) be points on a certain line;

slope = (y₂ -y₁)/(x₂ - x₁)

In this question the 2 points that lie on the line are: (-5,5) and (0,3)

slope = (3 - 5)/(0 - -5)

         = -2/5

Two families visited an amusement park. The first family bought 2 hot dogs and 3 bottles of waters, which totaled $18. The secon
Ghella [55]

<u>Answer:</u>

$6.00

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

To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.

Let's consider <em>h </em>to represent the cost of 1 hot dog, and <em>w </em>to mean the cost of 1 water bottle.

• For the first family:

2h + 3w = 18

We can rearrange the equation to make <em>w</em> the subject:

⇒ 3w = 18 - 2h

⇒ w = \frac{18 - 2h}{3}

• For the second family:

4h + 2w = 28

Since we have previously obtained an expression for <em>w</em> in terms of <em>h</em>, we can substitute that expression for <em>w</em> in the above equation, and then solve for <em>h</em>:

⇒ 4h + 2(\frac{18 - 2h}{3}) = 28

⇒ 4h + \frac{36 - 4h}{3} = 28

⇒ 12h + 36 - 4h = 84      [Multiplying both sides of the equation by 3]

⇒ 8h + 36 = 84

⇒ 8h = 48

⇒ h = \bf 6

∴ The price of one hot dog is $6.00.

Write an equation of the circle with center,( −2,8) and radius <br> 4.
marta [7]
The equation of a circle is defined by:
(x-h)^2+(y-k)^2=r^2
Where (h,k) s the center and r is the radius.

We can translate the word problem into (x+2)^2+(y-8)^2=16
