Answer:
you pay $69.74
Step-by-step explanation:
total cost without coupon: 15+65+14 = 94
apply the 30% discount ⇒ 94 × .30 = 28.20
subtract the savings ⇒ 94.00 - 28.20
total, after coupon, before tax ⇒ 65.80
apply 6% tax to 65.80 ⇒ 65.8 × .06 ⇒ 3.94
add tax to cost after coupon ⇒ 65.80 + 3.94
you pay $69.74
Answer:
a=-1
Step-by-step explanation:
6a+5a=11a
11a/11=-11/11
a=-1
x2 + y2 + 6x - 6y + 2 = 0
To complete square to a quadratic equation in its standard form we have:
ax2 + bx + c
Completing squares:
P (x) = (x + b / 2) ^ 2 - b ^ 2/4 + c
Keeping this in mind, we can complete square then:
x2 + y2 + 6x - 6y = -2
(x2 + 6x) + (y2 - 6y) = -2
((x + b / 2) ^ 2 - b ^ 2/4 + c) + ((y + b / 2) ^ 2 - b ^ 2/4 + c) = -2
((x + 6/2) ^ 2 - 6 ^ 2/4 + 0) + ((y + (-6) / 2) ^ 2 - (-6) ^ 2/4 + 0) = -2
((x + 3) ^ 2 - 9) + ((y - 3) ^ 2 - 9) = -2
((x + 3) ^ 2) + ((y - 3) ^ 2) - 9 - 9 = -2
((x + 3) ^ 2) + ((y - 3) ^ 2) - 18 = -2
((x + 3) ^ 2) + ((y - 3) ^ 2) = -2 + 18
((x + 3) ^ 2) + ((y - 3) ^ 2) = 16
((x + 3) ^ 2) + ((y - 3) ^ 2) = 4 ^ 2
Answer:
center: (-3, 3), r = 4
Answer:
x =
Step-by-step explanation:
Well first you have to isolate x so divide by 3/4 on both sides. when you divide a fraction by another fraction you multiply by the reciprical.(I think i spelled reciprical wrong, tell me if i did) Therefore you must multiply
1/7 by 4/3 giving you 4/21 which is equal to x.
