Answer: y=-2x+6

Step-by-step explanation:

$m=\frac{6-2}{0-2}=\frac{4}{-2}=-2$

So $y=2x+b$ . We can substitute (0, 6) to get:

6 = 2(0)+b

b=6.

Meaning y=-2x+6.

malfutka [58]

The average number of the gallons of milk consumed per week can be calculated below

number of weeks = 30

$\begin{gathered} average\text{ consume=}\frac{200+205+210+215+220+225+230+235+240}{30} \\ \\ \text{average consume per we}ek\text{=}\frac{1980}{30}=66\text{ gallons per w}eek \end{gathered}$

We are holding a 1k walk to raise money for walk across America. This organization provides shoes to people in need. It will be

Sveta_85 [38]

Answer:

The equations y=10x+250 and y=20x represent the situation.

Step-by-step explanation:

Given that:

Cost to rent the park = $250

Cost per person for t-shirt and snack = $10

Cost of participation = $20

y = cost

x = number of people

Cost for the organization;

y = 10x + 250

Amount generated from people's participation

y = 20x

Hence,

The equations y=10x+250 and y=20x represent the situation.

Find a ·<br> b. |a| = 60, |b| = 90, the angle between a and b is 3π/4.

sergey [27]

By definition, the dot product between two vectors is given by:

$a.b = | a || b | cos (\alpha)$

We have then that for this case:

$| a | = 60$

$| b | = 90$

$\alpha = \frac{3\pi}{4}$

Therefore, substituting values we have:

$a.b = | 60 || 90 | cos (\frac{3\pi}{4})$

$a.b = -3818$

Answer:

The product point of the vectors is:

$a.b = -3818$

Point B has coordinates (3,2). The x-coordinate of point A is negative 9. The distance between point A and point B is 15 uni

kumpel [21]

Answer:

(-9,9) or (-9,-7) are the possible coordinates

Step-by-step explanation:

We can use the formula for the distance between two points to get this

Mathematically, this can be;

d = √(x2-x1)^2 + (y2-y1)^2

Now let our point A be (x1,y1) = (-9,n)

let’s say y1 is n for now

For point B, we have (x2,y2) = (3,2)

and our d is 15 units

Inputing the values, we have

15^2 = (3+9)^2 + (2-n)^2

225 = 144 + (2-n)^2

225-144 = (2-n)^2

(2-n)^2 = 81

(2-n) = √(81)

2-n = -9

or 2-n = 9

n = 11 or n = -7

Now the possible coordinate values of point A are;

(-9,9) or (-9,-7)
