Answer:

x=-5 and y=-3

Step-by-step explanation:

-6y+2=-4x convert this into standard form

  y=x+2

  plug in the slope intercept form in to y

  -6(x+2)+4x=-2

  -6x-12+4x=-2

  -2x-12=-2 now solve for x

  -2x-12+12=-2+12

  -2x=+10

  x=-5 now solve for y

  y=-5+2

  y=-3

  so basically x=-5 and y=-3

Azmir's checking account pays 0.75% interest monthly and has a $7.50 service fee. If Azmir's balance last month was $825, find t
svetlana [45]

Answer:

Debit of $ 1.31

Step-by-step explanation:

Here, the initial amount in the account = $ 825,

Monthly interest on the amount = 0.75 % of initial amount

=\frac{825\times 0.75}{100}

=\frac{618.75}{100}

=$ 6.1875

And, the service charge = $ 7.50,

Thus, the final amount = Initial amount + Monthly interest - Service charge

= $ 825 + $ 6.1875 - $ 7.50,

= $ 823.6875

So, the total changes in the amount = final amount -  Initial amount

=  $ 823.6875 - $ 825 = -1.3125 ≈ - 1.31

Since, negative sign shows the amount is debited,

Hence, the amount of debit to his account is $ 1.31.

Can someone pls tell me if this is correct? For the properties, <3 and the bottom one too
saul85 [17]
1. Commutative property of multiplication This is because it represents a*b=b*a
2. Associative property of multiplication. Multiplication problems end with the same product no matter the order of factors.
3. Correct
4. Correct
5. Associative property of addition. Even though the grouping symbols are different, it is equivalent because you are adding all the terms together.
6. Correct

The last one should also be associative property since it applies every time you combine like terms.
Just a reminder: Distributive property is only when you multiply in the form of a(b+c)=ab+ac
