C. You take the tip amount devided by 15%. Thats 0.15. You the get the answer 97.20
Answer:
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
Step-by-step explanation:
(h, k) (-9, -2)
Equation: (x+9)² + (y+2)² = 100
4 points: (1, -2) (-1, 4), (-3, -10) (-19, -2)
(-3, 6) is on the circle
check: (-3 + 9)² + (6 + 2)² = 36 + 64 = 100 = 10²
Answer:
Step-by-step explanation:
y+11<30
subtract 11 from both sides
y+11-11<30-11
y< 19
choice A
To solve for x, you undo what was done to x. The variable x is ...
- multiplied by y
- added to z
You "undo" these operations in the reverse order, so first we undo the addition of z. We accomplish that by adding the opposite of z:
... -10 -z = xy
Now, we undo the multiplication by y. We accomplish that by multipying by the reciprocal of y.
... (-10 -z)/y = x
We can rearrange this, if you like.
And, if you want, you can factor out the minus sign.
