How do you Subtract 9x^2 + 22x - 46 from 12x^2 - 8x + 12.
Luba_88 [7]

Subtract the x^2 terms from each other, then the x terms, then the ones without any x whatsoever.

(12x^2 - 8x + 12) - (9x^2 +22x-46)

First, we'll subtract 9x^2 from 12x^2

12x^2-9x^2- = 3x^2

Result: 3x^2

Next, we'll subtract 22x from -8x

-8x - 22x = -30x

Result: -30x

Finally, we'll subtract -46 from 12

12-(-46) = 12+46 = 58

Result: 58

Now, we can add these 3 results together.

First, we had 3x^2, then -30x, and finally 58.

Thus, our subtraction of

(12x^2 - 8x + 12) - (9x^2 +22x-46)

equals

3x^2-30x+58

Answer:

  (a)  $1430

  (b)  $1340

  (c)  Debit card

Step-by-step explanation:

(a) The debit card is funded by Jenny's checking account, so it cannot be used to spend more than her checking account balance. The most Jenny can spend using her debit card is $1430.

__

(b) Amounts purchased using her credit card add to the credit balance. The most Jenny can purchase is the difference between her current balance and her credit limit.

  Limit - balance = $2350 -1010 = $1340

The most Jenny can spend using her credit card is $1340.

__

(c) For a purchase of $1400, the amount available on Jenny's credit card is insufficient. She can make the purchase using her debit card.
