Answer:

k = 11

Step-by-step explanation:

Given the points are collinear then the slopes between consecutive points are equal.

Using the slope formula

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

with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)

m = \frac{-1-1}{1-5} = \frac{-2}{-4} = \frac{1}{2}

Repeat with another 2 points and equate to \frac{1}{2}

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)

m = \frac{4+1}{k-1} , then

\frac{5}{k-1} = \frac{1}{2} ( cross- multiply )

k - 1 = 10 ( add 1 to both sides )

k = 11

Ipatiy [6.2K]

Answer: ||q_{A}||=5, ||q_{B}||= 3, ||q_{C}|| = 0.

Step-by-step explanation:

The magnitude is an absolute value by definition. Hence, each element has the respective value:

||q_{A}|| = 5\\||q_{B}|| = 3\\||q_{C}|| = 0\\

You bought a magazine for $3 and two notepads. You spent a total of $13. How much did each notepad cost? *
sweet-ann [11.9K]

Answer:

$5

Step-by-step explanation:

We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,

⇒ Form the equation

→ 2n + 3 = 13

⇒ Minus 3 from both sides to isolate 2n

→ 2n = 10

⇒ Divide both sides by 2 to find the cost of one notepad

→ n = 5

The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.

Between 10 a.M. And 11 a.M., 48 people came into Brad's store. 40 of them made a purchase. What is the experimental probability
irina [24]

Answer: The required probability is \dfrac{5}{6}

Step-by-step explanation:

Since we have given that

Number of people came into Brad's store = 48

Number of them made a purchase = 40

So, the experimental probability that the next person to come into the store will make a purchase would be

\dfrac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\dfrac{40}{48}\\\\=\dfrac{5}{6}

Hence, the required probability is \dfrac{5}{6}

What is the slope of this line? <br> The coordinates are: (-4,5),(0,6), and (8,8).
Elodia [21]

Answer:


Step-by-step explanation:

we have to use the formula of slope here.

we know,

slope of the line passing through (x1,y1) and (x2,y2) is-

\frac{y2-y1}{x2-x1}

Here, the first two points are -

(-4 , 5) and (0,6)

So, the slope will be-

\frac{6-5}{0-(-4)}=\frac{1}{0+4}=\frac{1}{4}


So, the slope is-

\frac{1}{4}
