What is the question I don’t understand

The points are ( -4,6) , (-2,0) and (0,-6).

As we can see that as x value increases by 2 points , the y value correspondingly decreases by 6 points , constantly.

It means the date is linear.

So we can model the data using a linear model , or linear equation.

In the form y=mx+b

where , m is the slope of line and b is the y intercept .

y intercept is already given by the point (0,-6)

It means b=-6

to find the slope we use the formula

m=\frac{(y_2 -y_1)}{(x_2-x_1)}= \frac{(-6-0)}{(0-(-2))} = \frac{-6}{2} = -3

So m=-3

So we get the equation as

y=-3x-6

But she is using letter v

So the equation should be

v= -3x-6

3/y =6/y-2<br>I need help on this please<br>worth 15 points
Leto [7]

Multiply both sides by y...

(3/y)y-(6/y)y-2y

Simplify it...

(3/y)y=3

(6/y)y=6

3=6-2y

Subtract 6 from both sides...

-2y=-3

Divide both sides by -2...

y=3/2


The solution is y=3/2

Find quadratic equations with roots -5 and -2
algol13

Answer:

y=(x+5)(x+2)

Step-by-step explanation:

Intercept form of quatratics is the best way to solve this equation, since you're given the roots needed.

The intercept form equation is y=a(x-p) (x-q) [where p and q are your roots/intercepts].

So, you input the intercepts and get y=(x-(-5))(x-(-2)), so your final answer should be y=(x+5)(x+2).

June will spin the arrow on the spinner 5 times. What is the probability that the arrow will stop on A, then B, then C, then D,
inessss [21]
Ok so assuming the board only has 4 spaces to land on (A,B,C,D) all we need to do is weight the probability, 

1/4 x 1/4 x 1/4 x 1/4 x 1/4 = 1/1024 

To solve I put the number of favorable outcomes over the number of total outcomes, in this case we had 1 favorable outcome each time and a constant of 4 possible outcomes.

A cylinder has a volume of 132x cubic feet and height of 4 feet. What is the area of the base?
Bogdan [553]

Answer:

33π square feet

Step-by-step explanation:

Volume = base area × height

132π = base area × 4

or, base area = 132π/4

or, base area = 33π
