Answer:

A) (-4,-3), B) (-1,1.5), D) (0,3)

Step-by-step explanation:

First turn 4y - 6x = 12 to slope intercept form

(y = mx + b), by adding 6x on both sides in order to move it to the other side. So now you have

4y = 6x +12, next divide both sides by 4 in order to get y by its self. Now you have y = 6/4x + 3, since 6 can't be divided by 4 yet 12 can.

Lastly you graph it, here it is graphed for you above⤴⤴⤴

Hope this helped :)

There are eight shirts in your closet, three blue, two are black, one is green, and two are white. You randomly select one to we

Maru [420]

The probability of wearing blue shirts on both days is 3/28.

<h3>What is probability?</h3>

Probability is the measure of the likelihood of an occurrence.

Given:

8 shirts are available out of which 3 are blue, 1 is green and 2 are white.

P(blue on Monday) = 3/8

Now, 7 shirts are left to wear on Tuesday

P(blue on Tuesday) =2/7

So,

the probability of wearing blue shirts on both days = 3/8 * 2/7 = 3/28

What’s the answer to this?

Elina [12.6K]

Step-by-step explanation:

Line is passing through the points:

$(-2,\:3)=(x_1,\:y_1) \:\&\: (2,\:5)=(x_2 ,\:y_2)$

Equation of line in two point form is given as:

$\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -3}{ 3 -5} = \frac{x -(-2) }{-2 -2} \\ \\ \therefore \frac{y -3}{ - 2} = \frac{x -(-2) }{-4} \\ \\ \therefore \frac{y - 3}{1} = \frac{x +2}{2} \\ \\ \therefore \: y-3= \frac{x}{2} + \frac{2}{2} \\ \\\therefore \: y= \frac{x}{2} + 1 +3\\ \\ \huge \red{ \boxed{\therefore \: y= \frac{1}{2} \:x+ 4}}\\ is \: the \: required \: equation \: of \: line.$

Which is the graph of y = _0.4x? A. B. C. D.

cestrela7 [59]

Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.

The instructions on the bag on concrete mix say to add 2 gallons of water to each 8 pounds bag of conceit mix

tiny-mole [99]

Answer:

4 pound

Step-by-step explanation:

From the question :

2 gallons of water = 8 pound bag

Number of pound bag per gallon of water ;

Let the number of pound = x

Using cross multiplication, we'll have :

2 gallons = 8 pounds

1 gallon = x pounds

Cross multiply

2x = 8

x = 8 /2

x = 4

Hence, 1 gallon of water mixes 4 pound bag of concrete.
