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

algol [13]

Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median

12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value
Answer is B.

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]

Answer:

$6.00

Step-by-step explanation:

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 h to represent the cost of 1 hot dog, and w to mean the cost of 1 water bottle.

• For the first family:

$2h + 3w = 18$

We can rearrange the equation to make w 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 w in terms of h, we can substitute that expression for w in the above equation, and then solve for h:

⇒ $4h + 2(\frac{18 - 2h}{3}) = 28$

⇒ $4h + \frac{36 - 4h}{3} = 28$

⇒ $12h + 36 - 4h = 84$ [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 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
