Write an equation in slope intercept form that is perpendicular to 3x + 2y equals 12 and passes through the point (1,2)​
Zigmanuir [339]

Answer:

The equation is y = (2/3)x + (4/3).

Step-by-step explanation:

First, you have to change the equation into slope-intecept formula to find its gradient (slope) :

3x + 2y = 12

2y =  - 3x + 12

y =   - \frac{3}{2}x  + 6

Given that when a line is perpendicular to the other line, their slope value multiplied, will form -1. Next, we have to find the slope for line :

m1 \times m2 =  - 1

-  \frac{3}{2}  \times m2 =  - 1

m2 =  - 1 \div  -  \frac{3}{2}

m2 =  \frac{2}{3}

Lastly, we have to subatitute the x and y values into the equation, to find its intercept value :

y =  \frac{2}{3}x  + b

let \: x = 1,y = 2

2 =  \frac{2}{3} (1) + b

b = 2 -  \frac{2}{3}

b =  \frac{4}{3}

y =  \frac{2}{3} x +  \frac{4}{3}

What is the slope of (2,2) (-3,-3)
Fiesta28 [93]

Answer:

The slope is 1.

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of \displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run }.

y2= (-3)

y1=2

x2=(-3)

x1=2

Solve.

\displaystyle \frac{(-3)-2}{(-3)-2}=\frac{-5}{-5}=\boxed{1}

As a result, the slope is 1.

A worker wants to save enough money to buy new
allochka39001 [22]

Answer:

The least amount of numbers that he can work at his job to have enough for the headphones he wants is 17 hours.

Step-by-step explanation:

To find the number of hours you could divide the cost of the headphones by the amount he earns each hour so you would do $119/ 7 to get 17 and then you could check your answer with multiplication by multiplying 7 * 17 to get 119 which shows that he has to work at least 17 hours to get the headphones he wants.

$119 / 7 = 17

17 * 7 = 119

Clarence collected data from a random sample of 900 working residents in his town asking whether or not they commute less than 1
Alekssandra [29.7K]

Answer:

Sample is biased

Step-by-step explanation:

If data contains an outlier therefore it is not possible for a single outlier to demonstrate such a dominant outcome for the sample statistics.

It would seem that the sample is biassed, and therefore it contains peoples commuting to work for less than 10 miles. And this can be the consequence.

Although the sample size is 900 and therefore sufficient size is required to come to conclusions.
