Answer:
B
Step-by-step explanation:
Okay, so this is a fairly challenging problem.
Parallel lines have the same slop, but different y-intercepts.
The new equation is y = 4/3 x + b
Now substitute x and y for the point's coordinates...
-4 = 4/3 (3) + b
(solve for b)
-4 = 12/3 + b
-4 = 4 + b
b = -8
The final equation is:
y = 4/3 x - 8
In point-slope form, this is B
X² + 6x + ____ - (y² + 4y + ____ ) = -4 + ____ + ____
x² + 6x + 9 - (y² + 4y + 4 ) = -4 + 9 + -4
(x + 3)² - (y + 2)² = 1
Answer: B
Answer:
1. A 2. B
Step-by-step explanation:
I'm not certain, but I'm thinking it's right
Total of $7.75
13 more quarters than nickels
15 nickels = $0.75
28 quarters = $7.00
28 - 15 = 13 coins
$7.00 + $0.75 = $7.75
She has 15 nickels and 28 quarters.
