What is the equation of the line that passes through (–2, 3) and is parallel to 2x + 3y = 6?

Zinaida [17]

2x + 3y = 6
3y = - 2x + 6
y = -2/3x + 2....slope here is -2/3
A parallel line will have the same slope

y = mx + b
slope(m) = - 2/3
(-2,3)...x = -2 and y = 3
now we sub, we r looking for b, the y intercept
3 = -2/3(-2) + b
3 = 4/3 + b
3 - 4/3 = b
9/3 - 4/3 = b
5/3 = b

ur equation is : y = -2/3x + 5/3 (slope intercept form)

y = -2/3x + 5/3
2/3x + y = 5/3
2x + 3y = 5 (standard form)

vichka [17]

Answer:

22x + 33y + 11z

Step-by-step explanation:

11(2x + 3y + z)

11 * 2x + 11 * 3y + 11 * z = 22x + 33y + 11z

Mortgage (monthly)

rodikova [14]

Answer:

Amount you could save per month if you take 25% of your discretionary monies and put it in a savings account is $209.68

Step-by-step explanation:

Expense Amount Per Month Expenses

Mortgage (monthly) $985.64 $985.64

Cell phone (monthly) $58.30 $58.30

Groceries (twice a month) $154.00 $308.00

Clothing (monthly with $180.00 $180.00

25% job–related )

Water & electric (monthly) $128.40 $128.40

Weekly dinner & movie $55.00 $220.00

Property taxes (6 months) $684.80 $114.133

Car insurance (quarterly) $330.00 $110.00

Groceries multiplied by 2 as you buy them twice a month. Dinner and movie on weekly basis, so you multiply it by 4. Car Insurance you pay for 4 quarters. 1 quarter has 3 months so, you divide 330 by 3, to find the amount paid per month. Rest of the data is monthly expense.

So, your total fixed expense per month = $ 2104.473.

Discretionary income = Income - Expense.

Discretionary income = $ 2,943.20 - $ 2104.47

= $ 838.73

Now, you are saving 25% of the discretionary income into your account. So, 25 % of $838.73 is your saving

Amount you could save = 25 % of $838.73

= 0.25 x $838.73

= $209.68

Insert a digit in place of each “…” to make numbers that are divisible by 6 if it

yarga [219]

Answer: Either 2, 5, or 8

This means the number 426 is divisible by 6. So are 456 and 486

===============================================================

Explanation:

A number is divisible by 6 if both of the following are true

The number is divisible by 2
The number is divisible by 3

This is simply because 6 = 2*3. So if 6 is a factor of a number, then 2 and 3 must be factors.

To have 2 be a factor, the units digit must be in the set {0,2,4,6,8} which is the case here (the units digit is 6 in this case). Therefore we know the number is a multiple of 2 regardless of what the other digits are.
To have 3 be a factor, the digits must add up to a multiple of 3. Through trial and error, we see that 0 doesn't work because 4+0+6 = 10 which is <u>not</u> a multiple of 3. Same goes for 4+1+6 = 11, but 4+2+6 = 12 is a multiple of 3.

Therefore, 426 is a multiple of 6

Increment that middle digit 2 by 3 and we jump from 426 to 456. Those three digits add to a multiple of 3 as well (4+5+6 = 15). Following that line of logic, we go from 456 to 486 as the last possible three digit number that has these conditions of having 4 first and 6 last, and the number is a multiple of 6.

-------------------------------

In short,

The numbers 426 and 456 and 486 are all multiples of 6 since they are multiples of 2 and 3 at the same time.

So we could replace that middle digit with either 2, 5 or 8.
