We can still use point-slope form on this question (even though others will use the standard form) We plug in the points: (0, -4) and (6, 0)

Remember the format? We can get the slope like this: y1-y2/x1=x2

Them we get -4-0/0-6 = -4/-6= 4/6=2/3

So 2/3 is the slope, and the y-int is -4

so we get y=2/3x-4

Can u show me common core way this problem how to do 5/9 ×3 1/2
ololo11 [35]
1.) you want to make 3 1/2 an improper fraction. so multiply 3 times 2 (your denominator) then add 1 (numerator). 
3x2= 6  6+1=7, then put 7 over your denominator which would be 7/2.
2.) multiply 5/9 times 7/2
5 times 7 is 35
9 times 2 is 18
your answer is 35/18
3.) make it a proper fraction
18 times 2 is 36 so that would't work to have two!
so you only can put 18 into 32 once so subtract 32-18 so you know what is left over after you take a whole out. 32-18=14. 14 is now the numerator and so put your whole number first then put your numerator over your denominator: 1 14/18
4.) simplify
1 14/18=  1 7/9, I divided 14 and 18 by 2 to simplify


The answer is 1 7/9

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. T
Julli [10]

Answer:

m= 4.8 months

Step-by-step explanation:

by taking  x as the money the International Business Club has at any time of the year,250.5 for their initial money, 35 as the money they spend every month and m being the month that have passed since the beginning of the school year; it all can be related to the following equation:  

x= 250.5 - (35*m)

And doing the same thing with the money from the Future Agricultural Leaders Club, associating their money to the variable y, the equation would be:

y=300 - (45.25*m)

as it is wanted to know at what month does both clubs have the same amount of money, x and y, must be the same, so:

250.5 - (35*m)  =300  - (45.25*m)

this equation can be solved by putting both terms that are related to m on the same side of the equality, and those who aren’t related on the other side:

(45.25*m)  - (35*m)= 300  -250.5

then, on the first side of the equation, m  can be taken out as common factor:

(45.35-35)*m=49,5

and solving for m:

m=\frac{49.5}{10.25}

m=4.8

show that 1/2 ÷ 3 =1/6 by using a model.Explain why the result is less than the number you started with 1/2
aleksklad [387]

Answer:

True

Step-by-step explanation:

Let's see if it is true....

                  1/2 ÷ 3

Rewritten,

                =1/2 ÷ 3/1

(All numbers have a denominator of 1)

Flip the pancake!

                =1/2 * 1/3

(When dividing fractions you flip one of the fractinons numerator and denominator)

The answer is,

                 =1/6

Therefore, the original statement  1/2 ÷ 3 = 1/6  is true!

Now the model is in the link below!

Hope this helps!
