Answer:
(-5, 2)
Step-by-step explanation:
<u>plug x into the equation x - 5y = -15</u>
-5 - 5y = -15
add 5 to both sides: -5y = -10
divide by -5: y = 2
It equals 6 21/79 aaaaaaa
Answer:
4 layers with <u><em>$2.84</em></u><em> </em>left over
Step-by-step explanation:
You start off with the cost of the cake which is <em>$12.96</em>, then add<em> $3.55</em> (in this case 4 times) until you get the closest number to <em>$30</em> without going over (<em>$27.16</em>) . You find the amount of money that is left over by subtracting you original amount <em>($30)</em> with the amount you spent total on the cake <em>($27.16) .</em>
I got the answer (-1, 1) hope this helps
The center (h, k) is (3, -1), and the radius r is 3. When you put those values into the formula
(x -h)² + (y -k)² = r²
you get
(x -3)² + (y +1)² = 9
This formula matches that of ...
C) (x-3)² +(y+1)² = 9
