Answer:

No, No, Yes, Yes

Step-by-step explanation:

We can simply substitute the pairs as x and y in the equation:

(5, 0)

7*5 + 5*0 = 35 + 0 = 35

35 \ne 9

(-4, -3)

7*(-4) + 5*(-3) = -28 - 15 = -43

-43 \ne 9

(2, -1)

7*2 + 5*(-1) = 14 - 5 = 9

9 =9

(-3, 6)

7*(-3) + 5*6 = -21 + 30 = 9

9 = 9

Llana [10]

Answer:

  k = 6

Flora made 7 withdrawals of $75 each from her bank account. What was the overall change in her account?
ZanzabumX [31]
Withdrawals are when cash is taken out from the account
Flora withdraws an amount of $75 at a time from her bank account
she makes 7 such withdrawals 
one withdrawal she takes out - $75
then seven withdrawals leads to - $75 x 7 = $525 
then overall change in her account has been a net withdrawal of $525
so the overall change in the account is -$525

In the game of euchre, the deck consists of the 9, 10, jack, queen, king and ace of each suit. players are dealt a five card han
Oksana_A [137]
0% because the deck only has 9s, 10s, jacks, queens, kings, and aces. There is no others cards accept those. So you cannot get a 4 of hearts because it’s not in the deck.

Find the slope of the line that passes through each pair of points. (-3, 1 )and (-17, 2)​
ASHA 777 [7]

Answer:

1/-14 or 1 over - 14

Step-by-step explanation:

The equation you need is: y2-y1  over x2-x1

So if you plug it in it becomes 2-1 over -17 -(-3) so 2 - 1 is 1 that's the easy part, 17 - (-3) is the hard part because you can't minus a negative. So it becomes -17+3 which is still -14 because you take the sign of the bigger number. Sorry if it's hard to understand :(
